Dusky-faced tanager

The dusky-faced tanager (Mitrospingus cassinii) is a species of bird in the family Mitrospingidae. It is found in Colombia, Costa Rica, Ecuador, and Panama.

The two subspecies are "very poorly differentiated." The adults are 18 to 18.5 cm (7.1 to 7.3 in) long and weigh 32 to 39 g (1.1 to 1.4 oz). Their crown and nape are mustard yellow. The face has a large black "mask". Their upper parts are lead gray. The throat is light gray transitioning to olive yellow on the breast and flanks and further to a gray-olive-yellow blend on the belly. The juvenile is similar but has less yellow on the crown and a buffy tinge to the underparts.
