Snail Kite

The Snail Kite is a medium-sized marsh raptor best known for its extraordinarily specialized diet and matching bill shape. Adult males are dark slate-gray overall with a white base and tip to the tail and bright red-orange legs and cere; females and immatures are browner with heavy streaking below and a pale, buffy face. In all plumages, the long, thin, deeply hooked bill is a giveaway, evolved specifically for extracting apple snails from their shells.

In the United States this species is best known from the Florida Everglades, where it is often called the Everglade Kite, though it is far more widespread through the wetlands of Mexico, Central America, and South America.

Key Field Marks

• Slender, strongly hooked bill, thinner and more curved than that of other kites or hawks
• Adult male: slate-gray body, white tail base, black tail band, red-orange legs and facial skin
• Female/immature: brown above, heavily streaked buffy-brown below, with a pale face and dark eye-line
• Slow, low flight over marsh vegetation with the head angled down, searching for snails

Similar Species

• Northern Harrier: also flies low over open habitat but shows a white rump patch and an owl-like facial disk, not the kite's hooked bill or wetland-restricted habits.
• Red-shouldered Hawk: chunkier with rufous shoulders and barred underparts, not associated with marsh-edge snail hunting.

Range

In the United States, Snail Kites are essentially restricted to central and south Florida, particularly the Everglades and Kissimmee-Okeechobee wetlands. The species is far more widespread from Mexico through Central America and much of South America.

Habitat

They depend almost entirely on freshwater marshes, shallow lake edges, and wet prairies that support healthy populations of apple snails, their nearly sole food source. Water level management and wetland health directly affect kite populations, making them a sensitive indicator species for Everglades restoration.

Feeding

Snail Kites fly low and slow over marsh vegetation, dropping down to snatch apple snails from just below the water's surface. They then carry the snail to a perch, extract the animal with a practiced twist of the hooked bill, and discard the shell, leaving telltale piles of empty shells at favored feeding perches.

Voice

Calls include harsh, cackling notes and grunting sounds, typically given during interactions between individuals or near the nest.

Nesting

Nests are shallow platforms of twigs and marsh vegetation built low over water in bushes, sawgrass, or small trees, often in loose colonies. Both parents share incubation and chick-rearing duties.
