Pale-eyed Thrush

The pale-eyed thrush (Turdus leucops) is a species of bird in the family Turdidae, the thrushes and allies. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. == Taxonomy and systematics == The pale-eyed thrush has a complicated taxonomic history. It was originally described in 1877 with its current binomial Turdus leucops. In the later nineteenth and early twentieth centuries it was placed in genera Merula and then Planesticus. For much of the twentieth century it was placed in genus Platycichla and for a time treated as a subspecies of the yellow-legged thrush (then P. flavipes, now T. flavipes). Following several phylogenetic studies, in the early twenty-first century taxonomic systems merged Platycichla into Turdus. The pale-eyed thrush is monotypic. == Description == The pale-eyed thrush is 19.5 to 23.5 cm (7.7 to 9.3 in) long and weighs 54 to 80 g (1.9 to 2.8 oz). The species is sexually dimorphic. Adult males are almost entirely glossy bluish black with sometimes some white on the chin. They have a bluish white iris and sometimes a pale yellow-orange eye-ring, a bright yellow to orange bill, and bright yellow to orange legs and feet that match the bill. Adult…
