Merle fauve

The Clay-colored Thrush, Turdus grayi, is a medium-sized songbird in the family Turdidae that ranges from eastern Mexico through Central America to northwestern Colombia. It is the national bird of Costa Rica, where it is common in gardens, parks, forest edges, plantations, and humid lowland and foothill forests from sea level to moderate elevations. The species is characterized by its uniformly clay-brown to olive-brown plumage, pale grayish-white underparts with faint streaking on the throat, yellowish-green bill, and yellow eye-ring. Formerly known as the Clay-colored Robin, it is closely related to the American Robin and shares the typical thrush body plan of a stout, medium-sized body with powerful legs for ground foraging. The Clay-colored Thrush is omnivorous, feeding on a wide variety of fruits, berries, earthworms, insects, and small lizards. Its melodious, flute-like song is considered one of the most beautiful in tropical America and is delivered throughout the year, intensifying before the rainy season in Central America. The species adapts well to human-modified landscapes including gardens and agricultural areas with scattered trees. It is assessed as Least Concern by IUCN with a large and stable population.
