Fulvous Antshrike

The fulvous antshrike is a large dark antbird, 22 to 25 cm (8.7 to 9.8 in) long and weighing 75 to 85 g (2.6 to 3.0 oz). The species exhibits significant sexual dimorphism, though both sexes have a crest, a brown to orange-yellow iris, a heavy black bill with a hook at the end like true shrikes, and black or dark gray legs and feet. Adult males are mostly black with irregular thin white bars everywhere but the throat. The bars on the face and crest are broken and appear as small spots. Voice: The fulvous antshrike's song is "a steadily repeated series of whistled notes, 'uué, uué, uué...' ". It has several calls. The most common is "a long...nasal, downward-inflected snarl variously expressed as churr, charrr, chakeeer, or mEw'urrr". Others are a "descending squeal described as peeeeeeh or peeeeeeyargh" and " a loud, repeated chee-chee-chee-chee-chee".
