Eastern Kingbird

How to find it

Plan a visit for one of the two migration windows and head for the Caribbean coast, where the flow is heaviest. Scan the sky at dawn, when the flow of migrants is strongest. Flocks often fly in and perch in the canopy, so watch the tops of trees and snags near the coast. Look through the swallow flocks overhead, because kingbirds mix with them. At Tortuguero the biggest flocks came in the morning, especially once the rain stopped.

How to recognise it

Adults are gray to blackish above, with a white belly and chest. The long black tail has a white tip, and the wings are long and pointed.

A red crown patch exists but is rarely seen, so do not count on it as a clue. On a perched bird, look for the dark back against the white front, then check the tail tip.

These details come from the species across its whole range, and they hold for the birds that pass through Costa Rica. In flight, flocks of hundreds look a lot like swallows as they mix with the swallow waves overhead, so the white-tipped tail is worth waiting for when a bird lands.

Behaviour and diet

The Eastern Kingbird waits on an open perch and flies out to catch insects in flight. Across its range it is aggressive in defending its territory, even against much larger birds.

Migrants in Costa Rica are calmer. They rest briefly in trees, catch insects in flight, and pick berries and arillate seeds. They roost in isolated clumps of trees or in tall coarse grass.

Where it lives

In Costa Rica it is a passage migrant on both slopes. It is often common in the Pacific lowlands and in the Caribbean lowlands away from the coast, and along the Caribbean coast it is often very abundant.

On migration it ranges from the lowlands up to about 1700 m in the central mountains. Large numbers gather in scrub along the Caribbean coast to feed on Cordia curassavica fruit.

When to see it

Southbound birds pass from late August or early September to late October, and October is a peak time on the south Caribbean coast. Northbound birds pass from late March to mid-May, and April is described as high time for spring migration.

Similar birds

Tropical Kingbird, the common resident kingbird, has a yellow belly and a plain brown tail, while the Eastern has a white belly and a white tail tip. Fork-tailed Flycatcher looks similar, but the Eastern Kingbird has a square tail with a white tip. Western Kingbird is paler with a bright yellow belly, and it is a rarer migrant in Costa Rica.

Names and lore in Costa Rica

Costa Ricans use Tirano Norteño for this bird, and the AOCR list adds Viuda Negra. Other Spanish names elsewhere include tirano oriental, tirano dorso negro and tirano viajero.

Status and conservation

The AOCR list marks it as a migrant (M), a passage migrant on both slopes that is often common to very abundant.

Photography tips

Flocks often fly in and perch in the canopy, so watch the tops of trees and snags near the Caribbean coast. Scan the sky at dawn, when the flow of migrants is heaviest, and keep an eye on open perches for a bird that flies out after insects and returns.
