Rufous Treepie
Dendrocitta vagabunda
A long- and stiff-tailed bird with primarily rusty-brown upperparts and dull orangish underparts. The head, mantle, and neck region are a dull, sooty black. The long graduated tail is pale gray with a wide black terminal band. Note the conspicuous silvery-gray, white, and black patterns on the wings. The blackish-gray bill is stout with a hooked tip. Found in a wide range of habitats from woodlands to scrubby patches, singly or in pairs feeding in the treetops. The call is a loud metallic “krowwiiii kroo.”
Black-breasted Barbet
Pogonornis rolleti
Large, mostly black barbet with a huge white bill. Note the black breast and the red, white, and black belly. Found locally in savanna, woodland, gardens, and secondary growth, often in the vicinity of figs and other fruiting trees. Usually in pairs or small groups. Gives rasping calls and a nasal yelping call. Somewhat similar to Bearded and Double-toothed Barbet, but easily separated by the black rather than red breast.
Unicolored Thrush
Turdus haplochrous
Drab thrush endemic to floodplain forest of the Río Mamoré and tributaries surrounded by the flooded Moxos grasslands in El Beni, central Bolivia. From similar Hauxwell’s and Black-billed Thrushes by dull olive bill, exposed yellowish orbital skin, and relatively plain throat. Difficult to see, mainly because most of its habitat is tough to access. Song low, full whistles, 5-6 notes with little variation. Calls short full notes, or longer nasal calls.
