Swallow-tailed Kite

Overview

The swallow-tailed kite (Elanoides forficatus) is one of the most instantly recognizable raptors in the Americas — and also one of the most graceful fliers anywhere. Adults are 50–68 cm long with a wingspan of 1.12–1.36 m and display a strikingly clean pattern: jet-black back and wings contrasting with a pure white head, breast, and underparts. The deeply forked, scissoring tail is unique among North American raptors and gives the bird its common name.

This kite forages almost entirely on the wing, plucking large insects, small lizards, frogs, snakes, and nestling birds from vegetation without pausing flight. It also eats fruit — unusual for a raptor — and has been documented drinking by skimming water surfaces in low passes. Satellite-tracking studies have documented individual migration journeys exceeding 10,000 miles round-trip.

Why Tortuguero

Tortuguero lies directly under one of the principal Caribbean-lowland migration corridors for this species. Northbound birds — often in loose flocks of tens to hundreds — move through the region from January through May as they travel from South American wintering grounds to breeding areas in the southeastern United States and Central America. The combination of large wetland-forest patches and the linear canal corridor that funnels the landscape makes Tortuguero a reliable watch-point.

Small numbers of non-breeding individuals linger in the lowlands year-round, but the spectacle is the migration: groups of swallow-tailed kites working thermals above the forest canopy, alternately soaring and stooping to snatch prey, are one of the park’s premier wildlife moments.

How to see them (honestly)

• Best window: January through April for northbound migration. Peak often February–March.
• Where: scan the sky above the forest canopy, particularly on warm mornings when thermals develop. Open stretches of the main canal — where the sky is not blocked by the tree canopy — offer the best views.
• What to look for: the black-and-white pattern and deeply forked tail are unmistakable. Even distant specks resolve into something distinctive once the fork is visible.
• Behaviour: kites are not shy but they are not static — they work wide areas. Once you see one, watch for others; they frequently travel in loose groups.

Status note

Globally Least Concern, with a population that nests across a broad range from the US Gulf Coast to northern Argentina. The US breeding population has contracted significantly — roughly an 80% reduction from its historical range — due to forest clearing in the eastern United States, making this increasingly a bird of the tropics even within its breeding range. In Tortuguero, no direct threat applies: the park’s habitat is high quality and the species passes through annually.
