Many places have a Thrush species that has become adapted to living around people. In much of North America, American Robins are as synonymous with front lawns as sprinklers. Europeans have the Blackbird; immortalized in song by the Beatles and in prose by Shakespeare. In Costa Rica, Ticos chose the Clay-colored Robin (Turdus grayi) for their national bird. Opting for familiarity over splendor, it trumped spectacular species such as Resplendant Quetzal and Scarlet Macaw as well as undeniably cool birds like the Harpy Eagle. Clay Coloreds are THE garden bird of Costa Rica. Found from lowlands to cloud forest (where it gets replaced by the Mountain Robin), they sing a lot like their northern counterparts but are shyer; their presence usually revealed by their querelous, meow-like call. As their name suggests, Clay-colored Robins are also less colorful. My wife even goes as far as to call them downright ugly. These Yiguirros were at the Cinchona feeders. I think they look OK; judge for yourselves if you agree with my wife.
Monster Clay Colored Robin
Note the yellowish bill- field mark to separate it from Mountain and Pale-vented Robins.
