Unfortunately, Amazon World no longer has Spangled Cotingas (Cotinga cayana). In August last year, I saw a single male (a few years ago was a pair), in June this year he was gone.
Took care for several pale-throated bell birds ( always males ) - btw I know these birds under the name Bare-throated bell bird - in a Dutch privat collection and at Birdpark Walsrode and I must say, their voice is impresive !
