Peregrine chick banding canceled

It is with deep sorrow that we announce the loss of our 2025 UIC peregrine chicks. Regretfully, all four chicks suddenly passed away from unknown causes. We are having the chicks evaluated for cause of death by scientific staff from the Field Museum of Natural History.

While the loss of the chicks is difficult to accept, we are encouraged that our adult peregrines, Mouse and Loop, are doing well. We look forward to the 2026 peregrine nesting season.
