Cassique à bec jaune Amblycercus holosericeus

Retiring blackbird of thickets and tangles. Heard much more often than seen, as pairs keep in touch with ‘question and answer calling.’ Creeps methodically in vines and tangles, and most frequently seen as it flies low across a trail or quiet road, usually with one member of the pair following shortly after the other. Note the pale ivory-yellow bill and staring yellow eyes, often striking even with a quick flight view.
