Swainson’s Hawk – Cassidy
Name: Cassidy – Male
Species: Swainson’s Hawk
Liberty Arrival: 2020/Juvenile
Injury/Condition: Fractured left wing
Cassidy was brought to Liberty Wildlife as an immature, first year with a badly fractured left wing. Following a week in ICU, Cassidy began having severe sloughing of the tissue, an indication that his injury resulted from electric shock. Eventually, the left-wing tip was amputated, limiting his full flight capabilities. He was classified as non-releasable and assigned to the education team.
Swainson’s Hawk Facts
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: 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.
