Big Sur Update The month of January was surprisingly temperate here in Big Sur. Some rain drifted through here and there, but the interludes were nothing but warm, sunny, breezy days. The condors responded by moving leisurely through the Big Sur area. A current activity area is the regal stand of redwoods at the mouth of Pfeiffer Big Sur State Park. A brief climb up the Valley View trail inside the park will give a wonderful view of the condors in the tops of the trees. Other viewing possibilities are the sea lion beaches south of the Big Sur valley along the sheer and rocky coastlines. Condors fed on a sea lion that washed up dead near Coast Gallery this month, and they are still overflying that area. Gray whale migration is nearing its peak, and the view from a high coastal cliff could yield both a whale spout and a condor. Courtship displays continue, and pairs of condors can frequently be seen flying closely in formation, a sign that the two birds may become mates. Ventana biologists are monitoring the increased condor activity along the Highway 1 corridor. If you are passing through the area and see someone waving an antenna about, stop and say hi. We have recently added an new intern, Katy, who has been a huge help; there are now 4 people to monitor 18 condors! Pinnacles Update Last month's condor release at Pinnacles National Monument was quite a transition for both the newly released condors and for the biologists watching them. A couple of the condors had to be recaptured for brief "time-outs" in the Pinnacles flight pen, but as of January 24, all six condors are back out in the wild and doing great. They are all becoming skilled at landing in trees, and are refining their other flying skills. Condor 287 is still the most adventurous, expanding his range into the famed pinnacles inside the monument that gave the park its name. The prominent and striking rock faces in that area make wonderful perches for the condors and many hikers have seen condor 287 in the High Peaks area of the park. The other condors are sticking closer to the release area, but have recently been exploring Chalone Creek. This drainage has many large trees, and is a good roosting spot. The recent rains have also formed some pools, good drinking and bathing areas for condors. All of the wild condors at Pinnacles have black tags with white numbers painted on them. Since they are all young birds, their heads are gray and their white underwings are mottled with brown. There are quite a few Golden Eagles at the park, so look for the darker coloration, the wing tags, and the larger wingspan of the condor. The next group of condors to be released at Pinnacles will be transferred to the Pinnacles flight pen next month. The tentative plan is to release them next fall. By the time they are released, the condors in the wild now will be wonderful leaders for the new cohort. Until next time... --Jessica Koning, Big Sur Field Supervisor with input from Eric Stover, Interim Coordinator for Pinnacles
Big Sur Update In the grand tradition of February in Big Sur, there were some immense storms rolling off the famed pineapple express this month. High winds, heavy precipitation and power outages were the result. These conditions seem to inconvenience people far more than condors even though we live inside! Condors have feathers that are waterproofed by an oil gland at the base of their tail. Frequent and careful preening helps distribute this oil evenly over all feather surfaces. The water beads up and rolls right off of them! Condors also have an adjustable "hood" of delicate feathers they can use to keep their heads dry. The condors' favorite bad weather roost in the big redwoods at the mouth of Pfeiffer Big Sur State Park was used often this month. They like the top third of the biggest trees. A few condors have also been venturing further north, into the East Molera and Little Sur River drainage area. February is traditionally a month that has a lot of reproductive activity for breeding age condors. This February we received the news that two female condors released by Ventana Wildlife Society are behaving as though they are incubating eggs! These condors are currently residing in southern California. It has taken 5 years in the wild for our condors to reach breeding age, and we are very pleased that they are making this important life step. A wild condor chick has not fledged from its nest in California since the early 1980's, so we have great hopes for this breeding season. The condors overwintering in Big Sur are courting and showing pairing behaviors, but there is no sign as yet of reproduction. . Pinnacles Update The Pinnacles release site is progressing very well. Recent additions to the Ventana Wildlife Society staff monitoring that population have made the huge amount of work that goes into a new release site much more manageable. In future months, Curt Mykut will be writing the Pinnacles update, since he puts in so much quality field time there. The big news is that all 6 condors have been using the famous Pinnacles rock formations accessible via the High Peaks trail. This is evidence that their flying skills have improved and their range has increased. The High Peaks trail is an excellent way to enjoy the national monument and view condors. We have received many reports of people hiking in this area and getting fabulous views of the birds. Since condors are endangered please keep in mind that condors should never be fed or approached closely. Stay on the trails and respect signs that say "Closed area". Vultures are often curious, but condors that get comfortable around people often need to be recaptured. Please help keep all of the Pinnacles condors in the wild! Feel free to report your sighting to Pinnacles ranger staff or send us an email. Early in March, young condors from southern California will be transferred to Pinnacles. These condors will probably be released next fall, doubling the Pinnacles population to 12 condors. We are looking forward to the wild condors' response to the new birds in the flight pen. They are always interested in meeting new condors. --Jessica Koning, Big Sur Field Supervisor with input from Eric Stover, Interim Coordinator for Pinnacles Visit www.ventanaws.org to see photos and to get more information about the Condors. |
Big Sur Update March was warm and dry in Big Sur. These are conditions for excellent flying. Tracking the condors often involved following them in a vehicle as they flew up and down the coast within sight of Highway 1. Keeping up with them would be more or less impossible if they were not stopping frequently to circle in the thermals. These upwellings of warm air occur most often in the heat of midday. A thermal full of condors resembles nothing so much as a lazy tornado. People often remark on how infrequently condors flap their wings. Powered flight is generally only necessary on takeoff and landing, unless the condor is a novice flyer or the weather is nasty. However, the springtime is the season when condors are most likely to attempt some pretty daredevil flying maneuvers. Sometimes this is necessary when a condor blunders into a hawk's breeding territory and is chased out. During the breeding season, condors will chase each other at high speed, or line up for a head-on flyby that looks something like "chicken". With summer fast approaching, condor activity is increasing in Julia Pfeiffer-Burns State Park, about 10 miles south of Big Sur. Try getting up above to tree canopy on the left fork of the Ewoldsen trail for the best viewing! The condors overwintering in Big Sur are courting and showing pairing behaviors, but there is no sign as yet of reproduction. --Jessica Koning, Big Sur Field Supervisor Pinnacles Update Dear Ventana members and loyal visitors to "Notes from the Field": I would like to take this opportunity to introduce myself as the new condor program coordinator for the Ventana Wildlife Society. It really is an honor to be part of the Ventana team, and be involved with such a monumental endeavor. I would also like to express my gratitude to our former coordinator, Joe Burnett, for all of his service to Ventana's condor restoration program over the years. His dedication and innovative ideas are second to none and I am certain he will continue to make positive contributions to the recovery program from his new post at the Oregon Zoo. My recent move to California is proving to be a welcome change from the blustery, subzero winters of Michigan. Please visit the staff profile section of the website to gain a better perspective of my background and interests. I would like to devote the remainder of the text to the Pinnacles site and the condors. Before I proceed with the updates, I would like to welcome Katy McCune aboard as our new rearing specialist. She will be spending most of her time closely observing our young birds in the release facility and monitoring their progress. I would also like to recognize Liva Coe and Rachel Richardson, our field interns, for their dedication to the project. Field interns are an integral part of our condor program and contribute greatly to our daily field operations. Whether it is tracking birds, observing feedings, placing calf carcasses for the condors, or assisting with interpretation to park visitors, they keep things going. As Jessica Koning reported last month, the Pinnacles release site continues to progress extremely well. I am happy to report that we successfully transferred two young condors from the Hopper Mountain facility to our Pinnacles release facility in early March. This brings our Pinnacles population to eight individuals (6 free-flying and 2 captive). We plan to transfer four more young condors from the Los Angeles Zoo in late April. The two young females currently in the release facility are adapting extremely well to their new surroundings and have been interacting with Hoi (the adult mentor) and the six free-flying males on a regular basis. This was quite apparent during the first two weeks following the transfer as the free-flying birds were very curious about the new arrivals and spent more time around the facility. I look forward to observing, and reporting to everyone, the social hierarchy that will develop as four more young birds are brought into our release facility. Although the release facility, and tall pines in close proximity to the facility, are favored perch and roost sites of the birds, they continue to use areas within the park away from the release site. It is not uncommon to see the birds soaring over the high peaks in such locations as Hawkins Peak, Scout Peak, and Mt. Defiance. The birds have frequently utilized tall rock spires and grey pines in these areas as perches and roost sites. Although the condors' presence in the high peaks area of the park offers a unique viewing opportunity to park visitors, I can't stress enough the importance of maintaining your distance in the event that you come across a perched bird while using the trail system. These young birds can be very curious, so while your temptation may be to approach out of your own curiosity, or to get the perfect snapshot, this could have long term negative effects on the bird's behavior and potentially puts you and the bird at risk of injury. Our goal is to prevent the birds from developing any positive association with humans, so your cooperation will keep the birds wild and most certainly contribute to the long term success of the Pinnacles release site. A general rule of thumb is to maintain a minimum of 100 feet between yourself and a bird spotted while visiting the park. Further information can be acquired from the National Park Service's Pinnacles website and by paying a visit to the park and catching a glimpse of the birds first hand. Within the last two weeks of March the birds have begun to make movements outside of the park boundaries and have been using perch and roost sites on private and BLM land. This is evident from the GPS locations we have been receiving from condor 287 and from our daily radio tracking of VHF-marked condors. We currently have one GPS tag deployed and it belongs to condor 287, while the remainder of the birds are marked with conventional VHF radiotransmitters. It was quite fortuitous that 287 was chosen to wear a GPS tag since he seems to be the most adventurous individual in the group. He has made movements of up 20 miles to the east and south of the park. We suspect that other birds have recently made movements of this magnitude based on 287's locations and the fact that we have had two occasions where signals for the other five have disappeared to the east and south. 287, however, has been making these flights since release. Unfortunately, I do not have pictures to share with you for the month of March; however, I will include photos of the new birds in the release pen and hopefully some shots of our 6 free flying birds in the high peaks in the next edition of the field notes. I'm sure my format for the field notes will change as I settle into my new position, so please bear with me and feel free to offer suggestions. I will do my best to respond and make changes. Until next month! Cheers -- Curt Mykut, Condor Program Coordinator
Big Sur Update April was an exciting month to be a condor biologist. We were thrilled to learn that female condors 161 and 192 both had eggs hatch around Easter Sunday! These two condors were released in Big Sur by VWS, but have spent most of the last 2 years living at the USFWS condor release site near Fillmore, CA. They are first-time mothers, and we have high hopes for both of them and their new chicks. On April 16, condor biologist Greg Gryniewicz discovered a dead sea lion washed up on a beach south of Big Sur. He watched it for almost a week, and eventually saw condors 164 and 242 feed on the marine mammal. Big Sur is the only area in the U.S. where there is a coastal condor population, and we are always excited to see them finding food here just like their ancestors did hundreds of years ago. Greg also saw over 50 whales (some of them breaching completely out of the sea!) and sea otters while he watched over the beach. We would like to welcome Joy Retzlaff, Amelia Brower, and Melanie Hibbard to the condor crew, and say goodbye to Melanie Banville and Greg Gryniewicz, who will be continuing their training as field biologists on the sky islands of southern Arizona. Thanks for all the hard work, and good luck! --Jessica Koning, Big Sur Field Supervisor Pinnacles Update Peak visitor traffic at the park certainly occurred during the month of April, and understandably so. Blooming wildflowers, mild temperatures for the first three quarters of the month, and of course the presence of California condors, drew quite a few people to the park. April was also an eventful month for the condor crew. Most notably condors 278 and 265 were recaptured and brought back into the release facility for temporary holding, and a new feeding site was established for the free-flying birds. So, much of our attention was drawn to observing the interactions amongst the various age classes within the release facility and determining how quickly the free-flying birds would find the new feeding site. The transfer of the four juvenile condors from the L.A. Zoo was postponed and will occur during the week of May 10th, so stay tuned for updates next month. The recaptures of 278 and 265 occurred on April 2nd and 6th, respectively. Condor 278 had been at the low end of the dominance hierarchy for sometime and was frequently observed being displaced during feeding events, had been seen using less than ideal perch sites on private land, and prior to his recapture had not been observed feeding for about 10 days. When he did finally attempt to feed he was pursued by a coyote and flushed from the feeding slope. To air on the side of caution we made the decision to recapture him, obtain a weight, ensure that he fed, and allow him to interact with the two younger females, possibly elevating his status amongst the older cohort once he is re-released. Since recapture, he has been doing quite well. He has been feeding consistently, has a solid weight of 19 lbs., and has interacted very well with Hoi, the mentor bird, and the two young females. His release date is pending, but should occur by the end of May. Condor 265 on the other hand was recaptured for the unfavorable behavioral patterns he was developing. More specifically, he was falling into a consistent pattern of being drawn towards human activity at the park. On three occasions he was observed perched at the top of popular rock climbing routes as climbing parties ascended. Instead of flushing he exhibited a sense of curiosity towards the climbers in all three instances. On two other occasions he was observed perching on low lying rocks adjacent to popular hiking trails as large groups of visitors observed him. Again, he appeared more curious than threatened and held his ground as the park visitors took pictures. In both instances he was hazed with a super-soaker water gun, but this did not seem to deter him since two of the interactions with climbers occurred after the hazing incidents. We felt that recapture and short term holding was the next step in an effort to break this behavioral pattern. This has been a successful technique used in the past and will hopefully prove effective for 265. Although 265 has been feeding well and maintaining a solid weight he will in all likelihood be held until the end of May. Not much new to report with regards to the two young females, 306 and 317. As expected, they are at the bottom of the pecking order with 265 and 278 now in the release facility, but this close social interaction with older birds will hopefully prove to be a positive experience for the youngsters. The remaining four free-flying birds continue to do well and have established consistent patterns with regards to diurnal and nocturnal habitat selection. Similar to what I reported in March, the birds continue to frequently use the high peaks area of the park as well as the ridge closest to the release facility as both perching and roost areas. 287 was the only bird that disappeared on a routine basis. I have included a map that was completed earlier in April which gives you an idea of the extent of his range thus far. Due to the presence of coyotes at our original feeding area, which seemed to be deterring the birds from feeding there, and the close call that 278 had with a coyote at the old site, we established a new feeding area. To ensure the exclusion of terrestrial predators we erected an electric fence around the new site and it took the birds about 4 days to locate the new area. They have been visiting the new site frequently and feeding there on a consistent basis. Our next step is to mount a camera that is activated by motion to 1.) confirm that terrestrial predators are not breaching the fence and 2.) photograph condor feeding events at close range. We have observed a number of other birds at the new area interacting with the condors, including turkey vultures, ravens, golden eagles and red-tailed hawks. However, none of the interactions have been aggressive. The May update should be an exciting one with the arrival of the 4 new juveniles! So be sure to check back in. Until next month! -- Curt Mykut, Condor Program Coordinator
Big Sur Update
Big Sur Update The biggest news for the month of June is that we will be releasing birds in Big Sur again in the fall! The USFWS brought us 6 chicks and a mentor bird on the 29th. They had a long drive from southern California but are now in the flight pen and doing well. Millie Brower, VWS intern, has accepted the position of our rearing specialist over the next several months. She will be monitoring the birds closely and making sure they are ready for release. The month of June was a little crazier than last month for the condor crew. There was also lots of training to finish with the three newest interns and it was the start of the busy summer time. Jessica Koning has certainly had her hands full with training us all at the same time and we are very grateful for all that she has taught us in such a short time! Joy Retzlaff, VWS intern, has also accepted the position of crew leader and will be taking on more responsibilities as well. Last month there were very few condors around, 3 or 4 at the most at one time. This month our numbers nearly doubled and we had 7 or 8 condors here through most of the month. A number of our previously released birds that were residing at Hopper Mountain in southern California came back to join us for a while. It was nice to have them back! It seemed though that the more birds we had here the harder it was to keep them out of trouble. They all started concentrating in one area along Highway 1, probably due to a nearby feeding site at the time as well as a favorite perching spot. We started having problems with the birds getting too close to the highway, near cars and people. Because of the captive breeding process, the birds are not as "wild" as they should be and they do not seem to have the natural instinct of fearing humans yet. This is why it is important that people do not approach the birds and keep their distance. However, we had several incidents of people getting too close to the birds when they were up near the highway. Please remember they are endangered and to protect them we need to minimize human contact when at all possible. Along with keeping your distance, there are also laws against approaching, feeding or harassing endangered wildlife. If you see a condor in a situation that is unsafe, please call and notify us. We greatly appreciate getting calls from concerned people! During mid-June we were asked by the USFWS to go down to Southern California for a trap up of the birds. Many of the birds we have released here like to go down to that area and they currently had many of the Ventana birds down there, so we were glad to help out. The entire Big Sur crew and two condor people from the Pinnacles site joined us. The trap up went very well and they had many in the trap already by early morning. It was a great chance for the newer interns to get some close encounters and real hands-on activity. Mike Stockton from the USFWS, who has a long history of working with condors, gave us tips on how to handle the birds and keep safe. They had biologists and vets from the L.A. and San Diego zoos to check health of the birds, give shots and take blood. All the birds were also tested for lead poisoning. The levels were all relatively low. We also changed radio and GPS transmitters and put on new tags because they only last just so long. The birds did very well despite the hot temperatures and we kept them cooled down with ice water. It was really wonderful to see so many condors flying free in one area! We had an unfortunate incident happen recently that involved potential lead poisoning with the wild birds. There was an injured horse that had to be put down in the area and after a couple of days the condors found it and were flying above, circling it. The animal had been shot with lead bullets, which could have cost us the lives of the entire population of condors had they fed on the dead animal. Luckily, we were called in time and were able to get rid of the lead before they got to it. This incident can be a reminder to all of us that using bullets made with lead is deadly to any animal that could come across it and ingest it. Along with a variety of online resources, there are many stores that carry non-lead alternatives. However, the majority of ammunition still used is made with lead. It takes only a small fragment of lead to kill a condor and they die a slow and painful death. This situation could have been a lot worse than it was and I hope that it will bring about more awareness of the issue of lead poisoning. Education and awareness are the keys to protecting our wildlife! --Melanie Hibbard, VWS Intern Pinnacles Update June temperatures at Pinnacles surprised me. We had a shift in late May to hot temperatures, but for the better part of June we remained below 90. I'm told that it won't last though, so heed my warning from May and be prepared for dry, hot conditions if you plan to visit Pinnacles and the condors. The first three quarters of June were relatively uneventful. The captive birds continued to progress and should be fully prepared for a fall release. We have chosen October 15 as the release date and will provide further details regarding the release by early September. 265 and 278 remained in the release facility for yet another month, but decisions have been made regarding their immediate future. 265 will continue to be held at our Pinnacles release facility and re-released at the end of October. I know for two months now I have stated that 278 would be re-released and it hasn't occurred. And while the retrices (tail feathers) that were causing concern have molted and he has made significant progress with regards to his reluctance to feed in a group setting we plan to hold him and re-release him just prior to the release of the second cohort. At this stage we feel that by continuing to expose him to the young cohort he may serve as a free-flying mentor to the youngsters when they are released. Prior to the last week in June all was well with our four free-flying birds and aside from an increased frequency in the number of significant flights outside of park boundaries we did not observe any aberrant behavior. By June 26th, however, things changed drastically and the crew had to respond to our first lead poisoning scare. On Saturday June 26th, one of our crew members made the first observation of Pinnacles condors feeding on a non-proffered carcass. Our initial reaction was not one of concern since the birds were feeding on what appeared to be a dead calf on one of the local ranches. Upon further investigation, however, we learned that not only had the calf allegedly been poached, but five wild pigs that were scattered throughout property may have been poached and possibly fed upon by the birds. Upon learning this from a local landowner we made the decision to trap the four free-flying birds and test them for lead exposure. Before we had a chance to begin the trapping process we observed 287, 270 and 266 feeding on a large cow carcass to the east of the park on private land. The cow may have been euthanized with a firearm (personal communication with a local landowner), so our concerns were heightened. By July 2nd we captured all four birds via the double-door trap at the flight facility and had field test results for lead completed by noon of that day. I am pleased to report that blood lead levels were low for all four birds and that all of them were subsequently released. Although it was a relief to learn that the birds had probably not been exposed to lead during these feeding events we understand that a significant threat still exists. Condors being obligate scavengers have a very high propensity for ingesting lead bullet fragments from poached animals or animals that are shot and un-recovered. This is one reason why it is so important for us to monitor the birds on a daily basis and make as many visual observations as possible. This allows us to better understand the frequency at which the condors are finding food on their own and to what degree the non-proffered food is posing a lead exposure risk. While lead ammunition is currently legal to use for hunting upland game, there are non-lead alternatives available that are not acutely toxic to condors, turkey vultures, and golden and bald eagles when they ingest bullet fragments from carcasses. Addressing the lead issue through education and awareness and working with the hunting community (which I am a part of) will be a critical component to successful recovery of the California condor. Until next month...Cheers! -- Curt Mykut, Condor Program Coordinator
Big Sur Update The month of July has been a hot one here in the foothills of Big Sur. It is often foggy down by the coast and we now welcome tracking in the clouds on these hot days. Despite the high temperatures, we are pleased to announce that the new chicks in the flight pen are doing well and are eagerly awaiting their release. The wild condors have been hanging around the pen most of the month and getting acquainted with the captive birds. We like this to happen because when the young ones are out in the wild these visitors will be important role models. A few weeks back, one of the chicks, 294, had somehow injured her eye while in the flight pen. Millie Brower, our rearing specialist, noticed she was keeping one of her eyes closed most of the time. When it did not get better, we had to take her into the vet for an exam. After treatment, she gradually got better as the days went on and now she is using both eyes normally and seems to be recovered 100%. We are very grateful she recovered because an injury that impairs vision can be deadly for condors. The chicks are all ready to go and have designated white tags with numbers already. It looks like the release may happen earlier than expected, sometime in the end of September. It will be a very exciting time but also worrisome for us as they go out on their own for the first time. Along with having our hands full with the chicks, we also had lots of wild condors in the area this month. We had 164, 167, and 171 from the blue tag or oldest cohort. We also had 190 and 194 from the yellow tags, and 204, 208, and 209 from the orange tags. The rest of the birds we had included 219 and 231 of the white tags and 236, 242 and 251 of the red tags. The red tags were most recently released and they have not ventured too far out of the area yet. The condors continue to move and perch along the Highway 1 corridor. Certain birds in particular have been utilizing coastal habitat and allowing close approach of people. Blue tag condor 171 was especially a problem getting too close to people on the highway. We made the decision to temporarily hold her in the flight pen with the chicks. Temporary holdings like these have been helpful in the past because they can break a pattern of concerning behavior. The main area of concern along Highway 1 is adjacent to a marine mammal colony where the condors have fed. The highway is simply a convenient place for a condor to survey the colony for food. It is also cooler down by the ocean and the coastal cliffs are perfect for the air currents helpful for easy take-offs. The problems arise when the condors get too close to the heavy traffic on Highway 1 and people see the birds and stop only to get too close. We had an incident in the beginning of the month where we were out tracking the birds along the highway and saw 208 flying low across the road and coming very close to being hit by an oncoming car. Millie and I pulled over to find a dead deer off the side of the road. 204 and 208 had found the deer and were probably feeding on it. Even though we supply food for the birds on a regular basis, they are by nature very curious birds and we have to keep a close eye on them when they are in areas of human development. With how busy we have been, it is a good thing that we hired a new intern to help out on the condor crew! Mike Tyner has had experience working with condors at Hi Mountain and has been a very valuable contribution to the team already. He will be with us for only a short time since he will return to school in September for graduate work. We look forward to next month and are optimistic about the future for the new birds. We plan on enjoying the rest of the summer in the presence of the condors! --Melanie Hibbard, VWS Intern Pinnacles Update July at Pinnacles was a relatively uneventful month considering the flurry of activity that occurred in June. A great deal of effort goes into rounding up condors for lead testing, not to mention the anxiety we all experienced waiting for results. So, I can speak for the whole field crew when I say that the lack of excitement this past month was welcomed and has given all of us a chance to re-energize and prepare for the upcoming fall release. Speaking of field crew, Ventana added two new interns to the field efforts at Pinnacles over the last month, Jennifer Mannas and Rebecca Rubin. Jen arrived from Florida where she recently completed her B.S. in wildlife ecology from the University of Florida and Rebecca from British Columbia where she has been working as a wildlife rehabilitator. They are welcomed additions to the Pinnacles crew and will be with us through January. While the free flying birds spent a large percentage of their time at the flight facility and the high peaks we did document a new condor use area in July. The first discovery was made via the use of 287's GPS tag. We knew that the birds had disappeared from the immediate park area, but did not realize the extent of the movement until receiving a map from our GIS specialist Eric Stover. 287 made his way approximately 40 miles south of the park to the Charley Mountain area south of highway 198. Upon initiating a conventional VHF telemetry search using 287's GPS coordinates we discovered that the other birds were using the same area. This is yet another example of the utility of GPS tracking technology. By relying solely on conventional telemetry we would probably never have discovered this area, because by the time we organized a search and identified search zone transects the birds would have likely made their way back to the release site. Our GPS tags on the other hand are programmed to collect data points once per hour, sixteen hours per day on a daily basis. Ventana currently has seven GPS tags deployed, with six of them attached to birds at our Big Sur site. By this fall we will have five more tags to deploy and plan to distribute a couple more to the Pinnacles site. With the increased usage of GPS tracking technology we will not only have a more effective means of locating our birds on a daily basis, but we will now have the ability to more effectively identify condor flyways, and roost and foraging sites. This, in turn, allows us to more easily identify threats or new use areas that may need to be protected and will ultimately allow us to implement the most effective conservation management strategies for condors. I would like to thank Cathy Keeran, our administrative assistant, and executive director Kelly Sorenson for putting together a new page on the web site regarding lead ammunition, so be sure to check it out. Until next month...Cheers! -- Curt Mykut, Condor Program Coordinator
Big Sur Update August was a little cooler than average here in Big Sur. Locals are starting to suspect an El Niño event for this winter. We are hoping that the weather remains calm for a while at least so the release goes well and the chicks can have time to adjust to their new environment. I am not sure who is more anxious for the release of the chicks in the flight pen, the condor biologists or the chicks. We have been spending many long days watching the birds to make sure their health remains good and they are demonstrating appropriate behaviors. According to our rearing specialist they are more than ready and can't wait to be out and flying free. The release is scheduled for Saturday, September 25th, but will be a very small event due to its remote location. There were fewer wild birds in the area this month than last. They also seem to be staying away from trouble and the highway. We had 10 different condors here throughout the month as they traveled back and forth from here and the USFWS site in southern California. For the oldest birds or blue tags we had 164, 167 and 171, who were held in our flight pen briefly and released again. We had only 194 here from the yellow tag bunch and 199 and 209 from our orange tags. We remain to have our red tag or youngest group here still, for they don't seem to venture too far yet but are getting to know the area well. We do have some unfortunate news to report on the wild nests down at Hopper Mountain. Blue tag 192, a Ventana released bird and her mate AC-9, a Hopper bird that actually was the last bird taken from the wild in 1987, are the parents of one of the chicks. We got a report from USFWS that the chick fell out of its nest and broke its wing. Condors nest in caves or holes in rocky slopes. Often the nests are on a vertical cliff, and eggs as well as the chicks have been known to fall out occasionally. The chick was taken in to the vet for examination and x-rays revealed that the chick had a broken wing, and bottle caps and rocks in its intestines that were fed to it by its parents. This is unfortunate since the parents do not mean to do their baby any harm but seem to be attracted to debris of this sort for unknown reasons. The injured chick will remain in captivity for now and hopefully will be able to be released with the next cohort to go out. The other chick belonging to a Ventana released bird, 161, is still hanging in there and we hope that it will fledge in early October although there is concern for its health as well. On a more exciting note, our orange tag bird 199 was spotted on August 15th at Pinnacles National Monument, Ventana Wildlife Society's other release site northwest of here. He is one of our older birds and fairly dominant. We have long wondered how long it would take our birds to find their fellow condor neighbors. 199 hung out around the site getting acquainted with the other birds there and flew back here on the 23rd. (See below for more details.) Time will tell if the other birds will follow in his lead. We hope to get through next month without any major problems and that everything goes as planned for the release. Once the chicks go out, our work has only just begun though, for we have to keep very close tabs on the birds all the time. Using radio tracking methods it will be key to try to locate every bird daily and make sure they appear to be in good health and are displaying appropriate behaviors in the wild. I know we are all getting excited and looking forward to seeing the new chicks flying free at last! --Melanie Hibbard, VWS Intern Pinnacles Update JPinnacles Update August was an exciting and eventful month at Pinnacles National Monument. With a surprise visit from a Big Sur condor, and the re-release of #270 and #278, we definitely did not experience a dull moment! The heat did indeed skyrocket, and there were several days where the temperature exceeded 100 degrees. I believe that the month of September will be similar, but the park should hopefully begin to see a significant decline in high temperatures. The highlight of the month was the arrival of an unexpected houseguest from Big Sur. On August 15th, an adult condor was observed hanging around the flight pen with a few of the juveniles. Once it was confirmed that Hoi, our mentor bird, had not successfully attempted a magical escape, we narrowed down the possibilities. #199, a five-year old male, had made his way to Pinnacles all the way from Big Sur! He quickly found the flight pen and made a connection with the younger birds. He was warmly welcomed by #266, #286, and #287, and all four were seen soaring high above the peaks and roosting together every night during his stay. The birds inside the flight pen were intrigued by #199 and although limited by the fence, their interactions were plentiful. Hoi seemed especially interested, and both birds were often seen mutually rubbing beaks through the fence. While #199 was in the park, we tried utilizing one of the new feeding sites in hopes that he would lead the birds to a carcass. Unfortunately, they never went to the site so we were unable to observe a group feeding with him. #199 did feed during his stay, and had no problem boldly displaying his dominance over #286 by flushing him from the carcass several times. Overall, there were not many aggressive interactions noted between the juveniles and #199. #266, #286, and #287 showed a genuine curiosity and interest in having an older bird around to emulate. After ten days of vacation, #199 finally headed back home to Big Sur. He has not shown up since, but this is one houseguest that will be welcomed back at Pinnacles any time! We finally re-released #270 and #278 back into the park and ultimately they made a smooth transition into the wild. #270 had no problem finding his place again amongst the free-flying birds. He was always a bit of a pushy bird and never had trouble socializing and feeding in a group setting. He has been roosting primarily in the high peaks with the others and sticking close to home for the time being. #278 has slowly been adjusting to being back outside of the flight pen. While he was being held in captivity, we documented signs of improvement with his social skills and ability to interact with other condors. During feedings, he seldom showed signs of apprehension and was often dominating the carcasses with #265 and #270 over the younger cohort. Since his re-release, we have not observed him communally feeding with the group. His flight skills are excellent and he has been seen kindly interacting with a few of the others. Nevertheless, he still seems timid and uncertain when it comes to feeding with the other birds around. We are keeping a close eye on #278, and hope that he is just one of those birds that may need a little more time. Last but not least, I'd like to mention that our newest interns Jen Mannas and Rebecca Rubin have been doing a wonderful job and we are very lucky to have them as part of the Pinnacles team. Thank you for keeping up with the Pinnacle release site, and stay tuned for next month's exciting details. -- Rachel Richardson, Pinnacles Field Supervisor Notes from the Field, September 2004 Notes from the Field, October 2004 Notes from the Field, November 2004 Notes from the Field, December 2004 |
