Bolivian Blackbird
Oreopsar bolivianus
Large, brown-winged blackbird of dry valleys in the high Andes of central and northern Bolivia. Prefers sparsely vegetated areas, such as Polylepis woodland, agricultural areas, towns, cactus forest, and scrublands. Brown wings are distinctive, but note that second-year blackbirds of other species (Chopi Blackbird, Shiny Cowbird) can show contrastingly brown retained juvenile wing feathers. Generally forages singly or in small groups, and sings from exposed perches. Song a simple, repeated two-part “pe-chew” given 3-8 times.

Vietnamese Cutia
Cutia legalleni
A bulky, heavyset bird with a murderous-looking hooked bill. Very similar in appearance to Himalayan Cutia, but ranges do not overlap. Male has blue-gray crown and wing patch, midnight-black mask, orange back and rump, and black-barred white underparts. Female of southern population is much duller, with a dark brown head and streaked brown back. (Northern female has not yet been described.) Inhabits both broadleaved and coniferous hill forest. Moves sluggishly, often in mixed flocks. Song is loud and repetitive, consisting of somewhat twangy whistles and more fluid, warbled notes.

Tropical Kingbird
Tyrannus melancholicus
Large, ubiquitous yellow-bellied flycatcher found throughout most of Middle and South America, though tends to be uncommon at the far northern end of its range in the U.S. A classic “telephone wire” bird along roadsides and in towns. Prefers open areas with some trees and water. Most abundant in lowlands and foothills, but ventures up to over 3,000m in some parts of range. Listen for sharp, high-pitched twitters. Nearly identical to Couch’s Kingbird, which overlaps from Texas to Belize; best separated by voice. Larger and longer-billed than Western and Cassin’s Kingbird; also note paler brownish tail. Also very similar to White-throated (longer, forked tail) and Snowy-throated (dark mask) Kingbirds in some parts of South America.

Short-billed Pigeon
Patagioenas nigrirostris
Overall dark pigeon of humid evergreen forest in tropical lowlands. Lives mainly in the canopy, where it is hard to spot, although its far-carrying hoo’koo-koo-koo song is often heard and may help in locating it. Sometimes feeds on fallen fruit on the ground, where it can be seen beside quiet trails. Plumage is dark brownish above, with a pinkish head, chest, and underparts. Note the short black bill.
