Icterus gularis
Large bright orange oriole with thick dark bill, found in open shrubby woodland. Limited black on face and throat; black back and wings with white wingbar and orange shoulder patch. Young birds duller yellow. Most similar to Hooded Oriole but larger and stockier with orange shoulder patch and thicker bill.

行为
The bird lives in semi-arid areas with scattered trees, and open riparian woodland. The bird is a solitary nester as well, with an average of a quarter kilometer between nests. Little aggression has been observed in breeding season from this bird, and it is not known to be territorial.<p>In Texas, their breeding season ranges from late April to late July. Their nest resembles a small pouch made of moss, grass, palm fibers, weeds, strips of bark, and is lined with feathers. The nest may also hang from telephone wires. The nest is assumed to be built by the female, but it is not known how long this takes. 4–6 eggs are laid, and nestlings are fed and cared for by both parents.<p>The Altamira oriole is a forage gleaner, searching for food through the tree-tops to the near-ground bottom of the tree. Its diet includes fruit (small fruits, hackberries and figs) and insects, such as grasshoppers, crickets, and caterpillars.<p>The song of the Altamira oriole is a series of clear, slow musical whistles. In contrast, the Altamira's calls are harsh whistles, rasping chatter, and nasal "ike"s.

Sickle-billed Vanga
Falculea palliata
Huge black-and-white vanga with a long curved bill. Juveniles have shorter bills. Madagascar endemic that is found at low elevations in spiny forest, dry deciduous forest, scrub, and plantations. Feeds by probing into cracks and crevices with its long bill, sometimes hanging upside down to do so. Very loud and vocal, giving a variety of calls including scolds, rasps, and a long wail that sounds almost like a human baby. Much larger than White-headed and Chabert Vangas, with a longer, curved bill.
Northern Red Bishop
Euplectes franciscanus
A very small gregarious species of open habitats including agricultural areas and the edges of marshes; often found in flocks of tens to hundreds. Note the black face and crown, brown wings, and long reddish orange uppertail coverts (concealing black tail) of breeding male. Nonbreeding males and females distinguished from similar Black-winged Bishop by smaller size and bill and told from Yellow-crowned Bishop by buffier coloration and more limited streaking on chest. Song is a rapid jumble of squeaky, twittering, and churring notes. Its calls include a sharp “tsit” and “tzit.”
White-breasted Wood-Wren
Henicorhina leucosticta
Very small, stub-tailed wren of humid tropical lowland forest. Favors forest understory, where usually found near or on the ground. Heard far more often than seen, and is notably elusive, even in fairly open understory. Common call is a metallic “peenk”; rather froglike and difficult to trace. Varied whistled songs rather short, usually introduced with a quiet whistled hiss. Note the boldly striped face, white bib, rich dark brown upperparts, and short tail. Gray-breasted Wood-Wren occurs in highlands.
