Main predators of adults are foxes, coyotes, wolves, bobcats, raptors, ravens, crows, raccoons, cats, skunks, snakes, dogs, & bears. Fire ants prey on young.
Like other falcons, they don’t build own nests.
During courtship, male brings female gifts.
They’ll hunt in sit-and-wait mode and/or on the wing.
Cache uneaten kills in hiding spots to keep thieves away & save it for leaner times.
Sometimes called American Sparrowhawk, Grasshopper Hawk, Windhover, & Killy Hawk (after shrill killy-killy-killy call).
Most common N American falcon.
Females lay 2-7 eggs per clutch & young stay w/ parents for a few months. Siblicide is not uncommon & 60% of youngsters don’t make it to maturity (around 8 months) due to this as well as car collisions, direct killing, & predation.
Besides “killy” call, also have “chitter” call for activities like courtship feeding/mating/feeding of young & “whine” call associated w/ feeding.

Fun Fact(s):
They have excellent vision, being able to see UV light & being able to spot prey more than 328 ft away.
Nests known to be quite smelly.
Very common in falconry, especially for beginners.
