About Addison
Addison arrived as a juvenile from another rehabilitation facility. She had a history of re-fracturing her wing and her leg. Upon initial exam, radiographs were taken, and it was confirmed she had multiple folding fractures, likely due to poor nutrition while developing. She is also extremely comfortable around humans. Because of her poor bone density and her habituation to humans, Addison is non-releasable.
Description
The Swainson’s hawk spends most of the year in the western United States extending into southwest Canada and south to west Texas.
Life Span
While many live less than two years, those that survive the first few years in the wild can live 8 to 10 years. The oldest known wild Swainson’s hawk lived to at least 24 years old.
Prey / Food
The Swainson’s hawk is somewhat of a generalist and eats whatever it can find. During the breeding season, as much as 90% of Swainson’s hawks diet will consist of small mammals. It will also hunt insects especially grasshoppers, crickets and locusts and birds, and occasionally reptiles and amphibians.
Babies / Nests
They build their nests in trees, shrubs, on the ground, or on top of utility poles. Clutch size ranges from one to four eggs but averages two to three. Incubation lasts for about 30 days. The young hatch and stay in the nest for another 30 days.
