How is the call of the Black-and-Yellow Tanager described in relation to the Silver-throated Tanager's call?
Answer
A scratchy 'tsew', which is higher pitched and faster.
While the visual appearance of the male is striking, vocalizations offer an important clue for confirming proximity, especially when birds are hidden in dense foliage. The vocalization of the Black-and-Yellow Tanager is described as a distinctive, scratchy sound rendered as 'tsew.' Critically, this call is differentiated from that of the Silver-throated Tanager because the *Chrysothlypis chrysomelas* call is higher pitched and faster in tempo. Further descriptions sometimes categorize its vocalization as a rapid, musical trill, but the scratchy, quick 'tsew' is a primary identifier.
