Young Bald Eagle
Arizona bald eagles tend to breed earlier in the year in comparison to northern populations. They lay one to three eggs from December to March, but mostly in January and February. The eggs take 35 days to hatch with the female and male taking turns incubating. Nestlings fledge at approximately 12 weeks after hatching (May and June) and are completely dependent upon the adults for food until they migrate north.
About 45 days after leaving the nest, the young migrate to Canada and northern California, Idaho, Montana, North and South Dakota, Oregon, Washington, and Wyoming. Two and three year old bald eagles also migrate annually to these destinations. It is unknown where non-breeding four year old and adult bald eagles travel to in late spring and summer. One to three year-old sub-adults return to Arizona in September and October. Resident adults will stay in their breeding areas year-round, although local short-term migrations are common.
