Western Kingbird

How to find it

Check open country with scattered trees, roadsides and wires, where it perches in the open. Power lines and fence posts at the road edge are worth scanning, and birds gather in groups that feed on fruit trees. Aim for the Pacific slope in winter, especially the North Pacific. Orotina, on the Central Pacific side, is one place visitors can look for it in the Pacific lowlands. Scan every yellow-bellied kingbird rather than assuming it is a Tropical, and check the pale breast, shorter bill and square, white-edged tail. Roosts shared with Fork-tailed and Scissor-tailed Flycatchers are worth a look too.

How to recognise it

Adults have a pale gray head with a darker mask and a pale grayish olive back. The throat and breast are pale gray, the belly is yellow, and the black tail has white outer edges.

A small reddish crown patch is normally hidden. Birds raise it only during courtship or when facing off against other species, so do not count on seeing it.

These marks describe the species in general. In Costa Rica the useful comparison is with the Tropical Kingbird: the Western is paler below, has a shorter bill, and has a square tail with white edges.

Behaviour and diet

It watches from exposed perches such as trees, shrubs or wires, then flies out to catch insects. It also eats fruit in fall and winter.

In Costa Rica it often joins the communal winter roosts of Fork-tailed and Scissor-tailed Flycatchers, so a roost may hold several flycatcher species at once. In Heredia, Western Kingbirds squabbled with Tropical Kingbirds and other birds, and the two kingbird species were seen in aggressive encounters.

Where it lives

In Costa Rica it prefers open areas with scattered trees. It is recorded from sea level to about 1000 m west of the Central Valley, and a study in Heredia extended its known elevation range in the country from 1000 m up to 1350 m.

Most records are on the Pacific slope south to the Térraba region. Conservation areas listed for it include Guanacaste, Arenal, Amistad Pacífico, Cordillera Volcánica Central, Osa, Pacífico Central and Tempisque.

When to see it

It is a sporadic winter resident, present from late October or November until April.

Similar birds

The Tropical Kingbird (Pecho Amarillo) is the look-alike. The Western is paler below with a shorter bill and a square, white-edged tail. A Costa Rican natural history account adds that the outer 3 primaries in females, or 4 in males, have thin tips, another feature that separates it from the Tropical. In Heredia the two were seen in aggressive encounters, so watching how they interact may help.

Names and lore in Costa Rica

Costa Rica, Mexico and Panama use the name tirano occidental. In Costa Rica the Tropical Kingbird that it resembles is known as Pecho Amarillo, and the AOCR lists the Western as Tirano Occidental (Pecho Amarillo).

Status and conservation

On the AOCR list it is marked M, a migratory visitor from North America that is found in Costa Rica as a sporadic winter resident.

Photography tips

Perches in the open make it approachable for the camera: look along roadsides, wires and fence posts in open country with scattered trees. Photograph the underparts and tail so the pale breast and square, white-edged tail show clearly against a Tropical Kingbird.
