Bald Eagle has surged: up 120× on the route-weighted index since 1968.

About the Bald Eagle

The Bald Eagle (Haliaeetus leucocephalus) is a North American member of the Hawks, Eagles & Kites (Accipitridae). In this analysis it is grouped with the birds of prey.

Size
17.5–39.5 in long (45–100 cm) — a medium to large raptor (typical for the family)
Habitat
Open country, woodlands, cliffs and wetlands, hunting from the air or a high perch.
Diet
Live prey — small mammals, birds, reptiles, fish and large insects (carrion for vultures).
Range
Recorded on 1,445 Breeding Bird Survey routes across 48 states, most concentrated in the Eastern Tallgrass Prairie.
Family

Bald Eagle Population Forecast

If the recent trend holds, Bald Eagle is projected to stay roughly flat through 2030, near 0.30 (95% range 0.25–0.35). A 5-year backtest shows a typical error of ±12.6%, with 60% of held-out values landing inside the 95% band.
