10/09/2025 Blue Pool Bluff female Peregrine Falcon has started perching closer to what has been the nesting cavity. The male Falcon made calls from a tree on top of the bluff. She then went into what has been the nest cavity. When he did not fly in she returned to her perch. The past Falcons generally woud start nesting late February to the first of March.
