Turdus grayi (Clay-colored Thrush; Clay-colored Robin)

Language: Spanish

Wikipedia Abstract

The clay-colored thrush (Turdus grayi) is a common Middle American bird of the thrush family (Turdidae). It is the national bird of Costa Rica, where it is well known as the yigüirro. Other common names include clay-colored robin. It ranges from South Texas (where it is rapidly expanding its range) to northern Colombia; west and north of the Isthmus of Tehuantepec. It is limited to the Atlantic slope, except for a population around Oaxaca City, Mexico that probably originates from escaped cagebirds.
