Swallow-tailed Kite
Swallow-tailed Kite
Elanoides forficatus
At a Glance
Our most beautiful bird of prey, striking in its shape, its pattern, and its extraordinarily graceful flight. Hanging motionless in the air, swooping and gliding, rolling upside down and then zooming high in the air with scarcely a motion of its wings, the Swallow-tailed Kite is a joy to watch. At one time it was common in summer over much of the southeast, but today it is found mostly in Florida and a few other areas of the deep south.

Migration & Range Maps
Migration is early in both spring and fall, with Florida birds arriving February-March, departing August-September. Some migrate around Gulf of Mexico but most Florida birds apparently cross Caribbean; their migration is poorly known.

Behavior
Eggs
2, sometimes 1-3. Creamy white, marked with dark brown. Incubation is by both parents, about 28-31 days.
Young
During first week after hatching, young are brooded almost continuously by female. Male brings food to nest, and female feeds it to young. After about 2-3 weeks, female also may hunt and bring food to nest. Young may move about in nest tree after about 5 weeks, first fly at about 5-6 weeks.
Feeding Behavior
Extremely maneuverable in flight. Catches flying insects in the air. Takes much of its food by swooping low over trees or lower growth, picking small creatures from the twigs or leaves without pausing. Young birds of other species are probably taken out of their nests.
Diet
Insects, frogs, lizards, birds. Adults apparently feed mostly on large insects at most times of year, including dragonflies, wasps, beetles, cicadas, grasshoppers, many others. Especially when feeding young, will capture many frogs, lizards, snakes, nestling birds. In tropics, also eats small fruits.
Nesting
Courtship may involve aerial chases by both sexes; male may feed female. Nest site is in tall tree in open woodland, usually in pine, sometimes in cypress, cottonwood, or other tree. Typically places nest near top of one of the tallest trees available, more than 60' above ground. Nest (built by both sexes) is platform of small sticks, lined with soft lichens and Spanish moss.
Climate Vulnerability
Conservation Status
Formerly more widespread in southeast, north as far as Minnesota, but disappeared from many areas in early 20th century. Current population apparently stable.
