Swallow-tailed Kite Identification Guide

Size & Shape

The Swallow-tailed Kite is a medium-large raptor, about 51-68 cm (20-27 in) long including its long tail, with long, narrow, pointed wings and an exceptionally long, deeply forked tail — the most distinctive silhouette of any North American raptor, unmistakable even at great distance or high overhead.

Plumage & Key Field Marks

• Plumage is boldly two-toned: brilliant white head, neck, and underparts contrast sharply with glossy black flight feathers, back, and the long forked tail.
• In good light the black areas often show an iridescent greenish-purple sheen.
• No other North American raptor combines this crisp black-and-white pattern with such a deeply forked tail, making misidentification unlikely once seen well.
• Juveniles look similar to adults but slightly duller, with a somewhat shorter tail fork.

Behavior

Swallow-tailed Kites are supremely aerial, spending much of the day in graceful, buoyant flight, twisting the tail to steer with minimal wingbeats. They catch and eat flying insects on the wing, and also snatch small vertebrates such as lizards, frogs, and nestling birds directly from tree canopies in flight, often eating prey while still airborne. They frequently forage and roost communally, sometimes in large pre-migratory flocks.

Similar Species

• No regularly occurring North American bird shares this combination of stark black-and-white plumage and a deeply forked tail; distant silhouettes might briefly suggest a large swallow or tern, but the kite's size and soaring flight quickly rule those out.
• Mississippi Kite overlaps in range but is uniformly gray with a squared or only slightly notched tail, entirely lacking the white body and deep tail fork.

Voice

Relatively quiet; the most commonly heard call is a thin, high-pitched, shrill whistle or squeal, often given near the nest or when interacting with other kites, but Swallow-tailed Kites are typically identified visually rather than by voice.

Habitat, Range & Season

Breeds in the southeastern United States, particularly Florida and the Gulf Coast states, favoring tall trees near swamps, river floodplains, and open pine or bottomland forest edges. Also breeds widely through Central and South America. U.S. breeders are long-distance migrants, arriving in spring (March) and departing by late summer, wintering mainly in South America; some resident populations occur farther south in the Neotropics year-round. Spectacular pre-migratory communal roosts can form in Florida in late July and August before birds depart.
