PHOENIX — A peregrine falcon chick hatched in a nest box on a downtown Phoenix high-rise was seen struggling this weekend, causing the Arizona Game and Fish Department (AZGFD) to take action. The wild peregrine chick, whose hatching was captured by a dedicated web-video camera, was having difficulty using its legs, causing it to fall and flail its wings.
AZGFD turned off the video feed on Monday morning, and while the peregrine parents were away, removed the chick from the nest box for examination. The chick was taken to the Phoenix Dog/ Cat/ Bird Hospital, where veterinary staff donated their services and took x-rays to reveal any physical problems. The bird was in acceptable health, but had splayed legs, which made it difficult for it to stand or move normally. Small splints were fitted to the bird’s legs to rectify the problem before it was placed back in the nest.
“We knew that shutting down the camera while we worked on the chick and monitored its recovery would disappoint the many people watching the peregrines,” said AZGFD Watchable Wildlife Program Manager Randy Babb. “We wanted to spare everyone the discomfort of watching the chick fall over while it adjusts to braces. We hope the cameras will only be off for a few days. This may be the first time a peregrine chick has been fitted with splints and returned to the nest for the adults to care for. Everything is looking good for the moment, and the parents are caring for the chick as if this disturbance never happened.”
Arizona Game and Fish biologists will continue to monitor the nest-cam and evaluate the chick’s progress over the next several days. Estimates are that, if all goes well, the chick’s splints may be removed in a week.
Two other changes will be noticeable when the nest cam is turned back on. A non-viable egg that had begun to rot was removed from the nest, and a new layer of brown artificial turf has been added to the bottom of the nest to provide better traction for the chick.
“While we are guardedly optimistic about the chick’s chances, despite our best efforts and hopes, sometimes nature has other plans,” said Babb. “It’s important to note that this chick is not out of the woods yet.”
The AZGFD peregrine web-camera is part of the department’s Wildlife Viewing program, which encourages Arizonans to learn more about the wonders of wildlife. A donation account (https://donation.azgfd.gov/donation) has been set up to help defray the costs of the department’s web-cameras.
