Черногорлый сальтатор Saltatricula atricollis

Charismatic noisy inhabitant of savanna, Brazilian caatinga, and shrubby areas where it is easy to see, perching conspicuously on bushes and fence wires. Often accompanies mixed-species flocks. It has an olive-brown back, a pale belly, and a buff vent. Note the orange bill contrasting with the black face and chin. Immatures have a dark bill. The song is a series of fast and melodic whistles.
