Black-and-yellow tanager

The black-and-yellow tanager (Chrysothlypis chrysomelas) is a fairly small passerine bird. This tanager resides in the hills of Costa Rica and Panama.

The adult black-and-yellow tanager is about 12 centimetres (4.7 in) long and weighs 12.5 grams (0.44 oz). The adult male has a bright yellow head, rump and underparts, and a black back, wings and tail. The wing linings are white. The male of C. c. ocularis differs in having a black spot on the lores. The female has olive upperparts and yellow underparts, but in Costa Rica and extreme western Panama (the sometimes recognized C. c. titanota) the throat and lower belly is whitish. She could be mistaken for a warbler or a female yellow-backed tanager. Immatures resemble the adult female.

The black-and-yellow tanager's call is a scratchy single or repeated tsew, higher and faster than that of the silver-throated tanager.
