White-eared Jacamar
Galbalcyrhynchus leucotis
Chunky-looking bird with a small head and a larger bill than other jacamars, recalling a kingfisher. Chestnut-colored overall with a pinkish-red bill. Occurs in humid upland and seasonally flooded forests, where it is most often seen flycatching from exposed branches, often in small groups. The song is a high, whistled “péeeuh- péeeuh- péeeuh- péeeuh.”
识别特征
The white-eared jacamar is 18 to 21 cm (7.1 to 8.3 in) long and weighs 44 to 50 g (1.6 to 1.8 oz). It is stouter than many jacamars, and has a more robust bill. It is almost entirely reddish-chestnut, with a bronzy gloss on the crown, wings, and tail. It has large white ear coverts. The juvenile is paler and its bill is shorter.
分类信息
The white-eared jacamar shares genus Galbalcyrhynchus with the purus jacamar (G. purusianus). They were originally treated a separate species, then as conspecific ("chestnut jacamar"), but are now understood to be separate species. The white-eared jacamar is monotypic.

分布与栖息地
The white-eared jacamar is found in the upper Amazon basin from Meta Department in central Colombia south through eastern Ecuador to the Ucayali River in northeastern Peru. It extends east into western Brazil along the Solimões (Upper Amazon) River almost to Manaus. In this humid region, it inhabits terra firme and várzea forest, both primary and secondary. It prefers edges such as around clearings and along waterways. In elevation it ranges up to 500 m (1,600 ft).

行为
The white-eared jacamar preys on insects, with Hymenoptera and Lepidoptera favored. It perches at mid- to upper canopy height singly or in small groups and sallies out to capture its prey.<p>White-eared jacamar nest cavities in Ecuador and Peru were in termite nests high in trees. The Ecuador nest was active in April and that in Peru in July. Breeding condition birds were recorded in June in Colombia.<p>The white-eared jacamar's song has been described as a "rising and accelerating...trill, “trrreeeeeeerrrr-reeeerrr-reeerr-reerreerr...” [1]. It also makes a loud "kyew" or "cue" call [2].

Straw-tailed Whydah
Vidua fischeri
A nest parasite that lays its eggs in the nests of Purple Grenadiers. As with other whydahs, breeding males are spectacular, whereas non-breeding males and females are drab. Breeding males are mostly black, with golden-buff coloring on the cap, the belly, and the elongated central tail feathers. Non-breeding males and females have a brownish back, a golden-buff head, and a red bill. Found in rather dry savanna and cultivated areas. Non-breeding male and female can be identified by their red bill and their almost unmarked plain buff head. Not very vocal, but does imitate Purple Grenadier, and gives a quick jumble of high-pitched whistled notes.
Blue Bunting
Cyanocompsa parellina
Unobtrusive small bird of brushy woodland and forest understory in tropical lowlands, mainly in drier habitats. Usually seen as singles or pairs, low in weedy growth. Male blue-black overall; with good views, note the blue forehead, ‘jowls,’ and rump. Female in West Mexico gray-brown overall, in East Mexico rich brown overall. Similar female Varied Bunting has a smaller bill and different call note: a wet plik; Blue Bunting call is a high tsik in West Mexico, a metallic chink in East Mexico.
Band-backed Wren
Campylorhynchus zonatus
Large, noisy wren, usually found in groups at middle to high levels in trees. Favors taller forest, from pine-oak woods in mountains down to evergreen forests in foothills; also gardens and orchards. Clambers along branches and pokes into bromeliads, sometimes in mixed-species feeding flocks with orioles and woodcreepers. Plumage is distinctive, with rusty belly, boldly spotted breast, and boldly banded back. Juveniles (seen in summer) are much duller and plainer.
