Standley Lake Regional Park Bald Eagles

Standley Lake Regional Park has been home to a pair of bald eagles (Haliaeetus leucocephalus) since 1992. When the eagles were first observed building a nest in the northwest portion of the property, Standley Lake officials closed off access to the area so the eagles would be undisturbed in their attempt to nest. Bald eagles usually mate for life and reuse nest sites. Because they are sensitive to human disturbance, it is imperative that the area remains closed to protect the nesting habitat.

The eagles at Standley Lake first produced offspring in 1996. They usually lay their eggs in the first weeks of February. Incubation lasts for a period of approximately 35 days, at which time 1 to 2 nestlings will hatch. These nestlings will first leave the nest in late May to early June, approximately 72 days after hatching. Both parents take care of the young eagles even after they leave the nest. The young will leave the area sometime before October or November, either on their own or when the parents force them out. The bald eagles at Standley Lake rely primarily on small mammals for food, but fish is an important part of their diet as well.

Viewing of the bald eagles can be done in several ways. You may walk in by parking in the lot at 100th Avenue and Owens Street and follow the trail from the southwest corner of the lot to the Nature Center. You may also drive into the park from the main entrance, which is located at 100th Avenue and Simms Street. A fee is charged for all vehicles entering the park. Once in the park, a trail can be accessed from the Nature Center that leads to a viewing blind. For the protection of the eagles, stopping along 100th Avenue or Alkire Street for viewing is not permitted.
