Gray Kingbird

Tyrannus dominicensis

In Spanish: Tirano Gris

  • Migrant

A rare autumn migrant on the Caribbean coast, hidden among kingbird flocks.

The Gray Kingbird is a large-headed, ashy gray flycatcher with a heavy black bill. In Costa Rica it is only a passage migrant along the Caribbean coast, with no breeding here, so the chance comes only while birds pass through.

The best setting to scan for one is a morning flock of migrating kingbirds on the Caribbean side, where it may travel with Eastern Kingbirds. A trip report from Tortuguero in October called Gray and Western Kingbirds pretty good migrants for Costa Rica, so a sighting counts as a real find.

On a trip we build around the Caribbean coast in autumn, that means early mornings watching the sky, the wires and the treetops.

How to find it

Go to the Caribbean coast in autumn and be out in the morning, when the coast is the best place in Costa Rica to see flocks of migrating kingbirds. Those flocks are a good setting to scan for a Gray Kingbird. October is a peak migration month, and a Costa Rican guide listed it among uncommon migrants in October 2019. Look for birds perched in the open on fences, utility wires or treetops, and listen for the rolling call. Check for the large-headed shape, then the gray back and white underparts.

How to recognise it

Start with the shape: a large-headed kingbird with a heavy black bill and a dark mask through the eye.

Upperparts: ashy gray.

Underparts: clean white, with only a faint gray chest.

Wings and tail: dark gray-brown, the tail slightly notched.

Crown: a hidden yellow or orange stripe, rarely visible.

A thick bill, a uniformly gray crown and back, no white tail tips and no yellow underparts separate it from other kingbirds. The Eastern Kingbird, by contrast, has a white tail tip. Check the large-headed shape first, then the gray back and white underparts.

Behaviour and diet

It sits on an exposed perch and sallies out to catch flying insects, its staple food. It will chase dragonflies and wasps in aerial pursuits.

Like other kingbirds, it defends its territory fiercely, even against much larger birds such as hawks and caracaras. It is generally tame and tolerant of people, bold and noisy.

In Costa Rica it may travel on migration together with Eastern Kingbirds, in flocks that are usually small, often under 20 birds.

Where it lives

Across its range it prefers open and semi-open country with scattered trees, usually near water on the coast. It also uses mangrove edges, pastures, parks and towns, and is mostly seen below 500 m.

The species winters in the southern West Indies, Panama and northern South America. In Costa Rica the birds we can hope for are travelling through along the Caribbean coast.

When to see it

In Costa Rica it is a casual or very rare migrant in September and October, and birds pass irregularly in mid to late March. Reports from the Caribbean coast fall in early to mid October, including 9 October at Manzanillo.

Similar birds

Its bill is heavier than that of the slightly smaller Tropical Kingbird, which has a yellow-olive chest rather than a white belly. The Eastern Kingbird has a white tail tip. In Costa Rica, Tropical Kingbirds react aggressively to Gray Kingbirds but seem to ignore Eastern Kingbirds, which can be a useful clue.

Names and lore in Costa Rica

Costa Rica uses the name tirano gris. Colombia says sirirí gris, Nicaragua tirano costero, Honduras chilero gris, and Puerto Rico and Cuba pitirre. The genus name Tyrannus means tyrant, a nod to the aggressive behaviour of these birds, and the species name points to Santo Domingo, where it was first described.

Status and conservation

The AOCR list marks it as a migrant (M), and only a few birds are reported from Costa Rica and Nicaragua.

Photography tips

Across its range it is easy to see on roadside fences and telephone wires, so a slow drive along open roads can help.
