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.

PHOENIX — After more than 30 days of anticipation by viewers around the world, the first of downtown Phoenix’s peregrine falcon eggs was welcomed on Mother’s Day after hatching at 7 p.m. on Sunday.

It’s anticipated that a second egg could hatch any time as an influx of viewers the world over monitor the Arizona Game and Fish Department’s wildlife camera live stream at www.azgfd.gov/livecams.

The falcon pair laid four eggs in late March, but two cracked and were discarded by the parents. The first chick hatched Sunday appears active, healthy and can be seen as the mother repositions herself on the nest.

“The live stream offers a unique, unobtrusive opportunity for viewers to witness one of nature’s wonders that is rarely seen,” said Randy Babb, watchable wildlife program manager for the Arizona Game and Fish Department. “Viewers will be able to follow the development of the young hatchlings and will want to stay tuned for the next important milestone in the young birds’ lives, fledging, which will occur about 30 days after hatching.”

Anyone with a computer, smart phone or tablet can watch the birds that live atop the Maricopa County Administration building in downtown Phoenix.

Game and Fish launched this live stream in early March when the pair was starting to display courtship behavior. Viewers can help support the costs of bringing the live feed to their homes by selecting the donation button found just below the viewing screen and making a small contribution.

Peregrine falcons have been nesting in the downtown Phoenix area for more than a decade.
Maricopa County partnered with the department and is allowing biologists to monitor the birds and access the nest site when necessary.

Peregrine falcons are one of the world’s most widespread raptors and are found on nearly every continent. The species nearly went extinct in North American from pesticide poisoning, but thanks to recovery efforts, the species was removed from the U.S.’s Endangered Species Act in 1999.

Peregrines feed almost exclusively on medium-sized birds such as pigeons and doves, which are plentiful in urban areas.
