Birdfinding.info ⇒  Secretive and hard to observe, but locally common in a few parts of its large range.  Most sightings of Yellow-breasted Crake occur at a handful of  widely scattered locations: in Brazil, the Tanquã reservoir of the Rio Piracicaba in São Paulo; in Costa Rica, Laguna Mónico and Medio Queso at Caño Negro Wildlife Reserve; in Honduras, around Lago Yojoa at Los Naranjos Eco-Archaeological Park and El Cortijo del Lago; on Jamaica, Black River Morass and Robin’s Bay; on Puerto Rico, Caño Tiburones, Barceloneta, Laguna Cartagena, and Humacao Nature Reserve; and on Trinidad, the Caroni ricefields.

Yellow-breasted Crake

Hapalocrex flaviventer

Tropical wetlands of Middle and South America.

Widely but patchily distributed in freshwater marshes at low elevations across the Neotropics from Mexico and the West Indies to central Argentina.  Difficult to detect, so its occupation of suitable habitat across its large range is likely much more extensive than the reported records indicate.

In the West Indies, known from a few sites in western Cuba, Jamaica, the Enriquillo Depression of Hispaniola, Puerto Rico, Trinidad, and Tobago.

In Middle America: reported from widely scattered points along coastal both plains from Sinaloa and Veracruz south to Panama.

In northern South America: the northern Colombian depression, the Llanos, and the Guianan coastal plain east to Amapá; also reported from the Pacific lowlands of Ecuador.

In eastern South America: northeastern Brazil from northern Maranhão east to northern Bahia; southeastern Brazil from Brasília and eastern Mato Grosso do Sul south through Minas Gerais to the coastal lowlands from Espírito Santo to Rio Grande do Sul; and the Paraguayan Chaco south through Argentine Mesopotamia to Buenos Aires Province and coastal Uruguay.  Also several scattered records from the interior of Amazonia (mostly northern Bolivia and Rondônia) and the Pantanal.

Identification

A sparrow-sized rail with a buffy or yellowish neck and breast, and a unique, angry-looking facial pattern: a bold white, broken eyebrow, framed by a blackish crown and strong black eye-stripe that forks at the eye.

Back and wings are rich buffy-brown or chestnut with contrasting black and white streaks and bars.  The flanks are barred black and white.

Bill is black or blackish-olive, slightly curved, and spike-like—proportionately long and heavy for a crake.

Legs are yellow-orange and proportionately large.  In flight, they hang down noticeably below the body.
