On October 18, two mature Peregrine Falcons were admitted to the Center as patients #13-2538 and #13-2539. The two falcons were found in a river in Essex County with their talons locked together. Peregrine Falcons typically establish their winter territories in early winter. The two birds were likely competing for a territory, resulting in a physical altercation between the falcons.
Based on plumage, it appears that #13-2539 is an older bird [it has a more black-and-white chest] and #13-2538 is a second-year bird [she has more brown on her chest]. #13-2538 has a federal band; she was banded as a nestling in New Jersey in May 2012 at the Burlington-Bristol Bridge. Dr. Dave McRuer spoke with Kathy Clark, the New Jersey Supervising Zoologist from the New Jersey Division of Fish of Wildlife, who was responsible for banding #13-2538. Kathy Clark reported that this falcon had three male siblings in the nest, and the zoologist was surprised that there was a territory dispute this early in the season. [Here is more information on Peregrine Falcon populations in New Jersey]. Both birds are believed to be female based on weights and measurements.
The younger falcon appeared to be mostly unscathed following the altercation. On October 18, #13-2538 presented with only a minor abrasion on her cere. Because the entanglement with another bird can be a stressful encounter, preventative measures were taken to support the bird’s healing – Dr. Rich Sim administered fluids, vitamin E, and an anti-inflammatory to assist with healing of any potential soft tissue injuries.
On October 19, an in-depth eye exam was performed and no damage to the eye was found. A fecal exam revealed signs of coccidia, and the falcon was given an antibiotic to treat the parasitic infection.
On October 21, radiographs were performed and were unremarkable. The falcon was moved to outdoor Flight Pen 4, and the veterinary staff will continue to monitor the bird’s appetite and attitude. Dr. Kristin Britton is hopeful that the falcon will only have a short stay at the Wildlife Center.
