October can be a busy month at the San Diego Zoo Safari Park’s Condor Breeding Facility. This is the time of the year when we start to prepare for the next breeding season: clean nests, conduct routine health exams, and provide maintenance to flight pens that were previously off-limits to keepers because of the presence of our young chicks slated for release to the wild. But before we can start anything, we need to move the recently fledged chicks to their new home—our socialization pen. Our remote socialization pen is approximately one mile from the main part of the Safari Park. On September 3, we moved this year’s Condor Cam chick, Kitwon, there to be isolated from any human activity and socialized with other fledglings her age. In the wild, condor chicks stay with or around their parents for up to 18 months. We don’t let them stay that long here at the Park. If we did, the next breeding season would probably be compromised; the presence of the fledgling may prevent the parents from breeding the next year, or the parents may turn aggressive to the chick if they try to nest again. Before her move, we affixed a wing tag to Kitwon’s left wing for identification purposes. She is now wearing wing tag Blue 13. She is sharing this large pen with three other condors: Ihiy (EE-hee): Female, 7 years old, wearing no wing tags. Unu (OO-noo): Female, 6 months old, wearing tag Red 6 (right wing). Spey (SPAY-ee): Female, 6 months old, wearing tag Yellow 15 (left wing). Soon, a fourth, younger chick will be joining the group; she has yet to fledge. California condors that are expected to be released to the wild are called “release candidates.” We raise all of our condor chicks as if they are release candidates until we hear otherwise from the U.S. Fish & Wildlife Service, who oversees the California Condor Recovery Program. Release candidates are isolated from humans. We offer their food through a chute in the wall. The pools are drained and rinsed from the outside of the pen. We don’t pick up any of their old food. The only time the birds see us is during a medical procedure: affixing wing tags, pre-shipment examinations, or West Nile Virus inoculations. These generally are not enjoyable experiences for the young condors, and that is what we want them to learn from us before they are shipped to the wild. We don’t want them to associate humans with anything beneficial. We are hoping to foster behaviors that wild condors would have—avoiding human activity and hazardous, artificial situations. Survival rates for condors that become accustomed to humans and human activity are very low. One of Kitwon’s new penmates has a very important role. Ihiy, the adult, is acting as the young birds’ new “mentor.” The mentor’s job is to facilitate the socialization of the fledglings. Condors are very social and, like us, need to learn the rules of how to interact in a group. The parent condors started this process when the chicks hatched, and continued it as the youngsters eventually fledged. Now that they are no longer living with their parents, the chicks’ “education” will be furthered by Ihiy. She will be the dominant bird in the pen, often displacing the fledglings from perches or roost sites or pushing them from the food until she has eaten first. The dominant birds at a site are usually the biggest ones, and often the most experienced. The young condors need to learn how to interact with these dominant and pushy birds in order to be successful in the wild. The socialization pen is very large with lots of space to fly around and exercise wings. There are several large oak snags on which to perch or roost. Also, there are two pools from which to drink or bathe. There are several ground level perches and boulders to hop around on, as well. It is interesting to see the social development of each bird. They can choose to perch next to whichever bird they wish, so they really get to know each other well. We have learned that young condors that aren’t well-socialized tend not to be successful once they are released to the wild. So far, Kitwon is integrating well into the group. She flies very well in the pen and interacts appropriately with her new penmates. Her parents, Sisquoc and Shatash, have done a great job preparing her for the big, wide world! As time passes, we should see the whole group settling in, perching, and feeding together. Feel free to post any comments or questions, and we’ll try to get them answered as soon as we can. Enjoy!
