Gray-breasted Crake

How to find it

Start with the voice. Learning its calls is the key to finding this crake, and you will probably hear it long before anything shows. Look for tall grass in wet pastures, riverbanks and shallow marshes. Because water level shapes where it lives, expect its habitat choice to shift with the seasons. In Costa Rica, each of the two crake species studied answered playback of the other's calls. Patient, careful listening matters more than scanning.

How to recognise it

This is a tiny crake, about 15 cm long and about 33 g. Look for these marks:

Head, neck and breast gray.

Crown blackish, throat whitish, belly white.

Back olive-brown, flanks barred black and white.

Bill dusky, with a yellow spot at each side of the base.

Tail black barred with white.

That last detail matters, because other Laterallus crakes have tails that are all black, red, or black and white at the sides.

Behaviour and diet

The crake is very secretive, which is why so little was known about it. It slips through dense grass along tunnel-like runways, so even a bird calling close by may never show itself. Expect to hear it more often than you see it.

It eats small insects, earthworms, other invertebrates and seeds. Across its range it is patchily recorded, probably because it is secretive and observers overlook it.

Where it lives

In Costa Rica it is found most often in wet pastures. Its habitat choice changes with the seasons, following changes in water level, so the same field may hold the bird at one time and not at another.

Across its range it lives in tall grass of wet pastures, riverbanks and shallow marshes. It also uses freshwater marshes, flooded rice fields, lake edges and floating grass mats, and occurs from the lowlands up to about 1700 m.

When to see it

A 1988 study says the species apparently breeds in the rainy season in Costa Rica.

Similar birds

The White-throated Crake is a common crake that shares its range in Costa Rica, so listen for differences in voice to separate the two. The black tail barred with white sets this bird apart from other Laterallus crakes, including the Ruddy Crake (Polluela Rojiza), which is also on the Costa Rican list.

Names and lore in Costa Rica

The Spanish name on the Costa Rican list is Polluela Pechigrís, and the country's other crakes also use the name polluela, for example Polluela Gargantiblanca for the White-throated Crake. That more familiar crake also carries the local nicknames Freidora and Huevo Frito, so you may hear those names in the field. No nickname is recorded for the Gray-breasted Crake.

Status and conservation

The official Costa Rican bird list marks it as a resident species, and a 1988 study found it locally common and widespread.

Photography tips

Photographs are hard, since the bird keeps to tunnel-like runways under dense grass. Learning its voice and listening patiently at wet pastures and marsh edges is the best way to improve your chances.
