Eagles, with their impressive wingspans and commanding presence, frequently capture public imagination. These raptors symbolize strength and freedom, making their populations and distribution across the United States a topic of widespread interest. The successful comeback of eagle populations from historical declines represents a significant achievement in wildlife conservation.
The State with the Most Eagles
Alaska is home to the largest eagle population in the United States. Estimates suggest that Alaska hosts between 30,000 and 50,000 bald eagles. This number represents a substantial portion, approximately half, of the entire bald eagle population found in North America. While golden eagles also reside in Alaska, their numbers are considerably smaller compared to the abundant bald eagle populations.
Why Alaska is an Eagle Haven
Alaska’s extensive and diverse natural landscapes provide abundant resources that support its large eagle populations. The state’s vast coastlines, numerous rivers, and lakes offer an ample supply of fish, particularly salmon, which forms a primary component of the bald eagle’s diet. These rich food sources are available throughout the year in many regions, sustaining large numbers of birds. Undisturbed old-growth forests, especially along coastal areas, provide ideal nesting and roosting sites for eagles, offering secure platforms for nests that can weigh over a ton and are used for many years. The relatively low human population density across much of Alaska also minimizes disturbance to eagle habitats, allowing them to thrive in vast, wild territories.
Monitoring and Conservation of Eagle Populations
Wildlife agencies and conservation groups employ various methods to track eagle populations, including aerial surveys and ground-based observations, which help estimate population sizes, identify nesting areas, and understand breeding success and distribution patterns. Historically, eagle populations faced severe declines, largely due to habitat loss and the widespread use of pesticides like DDT, which thinned eggshells and hampered reproduction. Successful conservation efforts, including the banning of DDT and the protection afforded by the Endangered Species Act, have enabled a remarkable recovery for these birds. These measures, alongside ongoing habitat protection, help ensure the continued health and stability of eagle populations across the nation.
The State with the Most Eagles
Alaska is home to the largest eagle population in the United States. Estimates suggest that Alaska hosts around 30,000 bald eagles. This number represents a substantial portion, more than 75%, of the entire U.S. breeding population of bald eagles. While golden eagles also reside in Alaska, their estimated population of about 13,000 individuals is considerably smaller compared to the abundant bald eagle populations.

Alaska’s extensive and diverse natural landscapes provide abundant resources that support its large eagle populations. The state’s vast coastlines, numerous rivers, and lakes offer an ample supply of fish, particularly salmon, which forms a primary component of the bald eagle’s diet. These rich food sources are available throughout the year in many regions, sustaining large numbers of birds; for instance, over 3,000 bald eagles can congregate in the Chilkat Valley in late fall and early winter to feed on spawned-out salmon. Undisturbed old-growth forests, especially along coastal areas, provide ideal nesting and roosting sites for eagles, with large, mature trees offering secure platforms for nests that can weigh over a ton. The relatively low human population density across much of Alaska also minimizes disturbance to eagle habitats, providing ample space for breeding and foraging.

Successful conservation efforts, including the banning of DDT in 1972 and the protection afforded by the Endangered Species Act, have enabled a remarkable recovery for these birds.
