Pale-headed Jacamar
Brachygalba goeringi
Small jacamar with a pale brown head and bluish-black wings and tail. Smaller than other jacamars in range, with a shorter tail. Note the brown breast and chestnut band on the upper belly that contrast with the white throat, belly, and undertail. Sexes similar. No overlap with the superficially similar Brown Jacamar. Locally common, found in pairs or groups in the top of trees or exposed branches in dry forest and edges, gallery forest, and savanna woodlands. Song is a series of high pitched notes that accelerate to end in shorter trills “weet, weeet, weeet, t’weet-t’ t’weet’ t’weet’ weet’ ti’ti’ti’t’t’t.”
识别特征
The pale-headed jacamar is 16.5 to 18 cm (6.5 to 7.1 in) long and weighs 16 to 18 g (0.56 to 0.63 oz). The male's crown, nape, and shoulders are ashy brown. The rest of the upper parts are dark brown glossed with greenish; they look blue-black when worn. It has a pale supercilium and a buffy-white throat. It has a chestnut band on the upper belly and dark brown flanks; the rest of the underparts are white. The female is almost identical. The juvenile has a gray crown and nape, and the upper parts are brighter and the green gloss stronger.

The pale-headed jacamar is found from Arauca and Casanare Departments in Colombia north through northwestern Venezuela at least to Lara. It primarily inhabits the edges of gallery and secondary forest in llanos grasslands. In elevation it ranges as high as 1,100 m (3,600 ft) but is usually found much lower.

行为
The pale-headed jacamar's diet is insects, mostly Lepidoptera and Odonata. It often perches on emergent branches in pairs or small family groups and sallies from there to catch its flying prey.<p>The pale-headed jacamar nests in burrows in earth banks. Nesting has been noted in Venezuela during April and May.<p>The pale-headed jacamar's song is a series of high "weet" notes that increase in speed and pitch and ends with a trill [1].

Flores Minivet
Pericrocotus lansbergei
A small, long-tailed songbird that perches upright. Male is largely black with white underparts, a contrasting red breast patch, red wing markings, and a red rump and outer tail feathers. Female is gray, lacking a breast patch, but shows red marks in wings, a red rump, and red outer tail feathers. Juveniles are scaled below. Pairs or groups can be found in canopy of forest and forest edge in the lowlands and hills on Flores, where it is the only minivet. Vocal, often uttering twittering calls, a high-pitched “tzee-tzee-tzee” or “tzee-tzee-tzew.” Also gives a short, sharp “pip” note.
American White Pelican
Pelecanus erythrorhynchos
Extremely large and conspicuous. White with black wingtips. Very long, orange bill with pouch for scooping up fish. Forages in flocks, swimming together to concentrate fish. Often soars in flocks, infrequently flapping, during migration and when traveling between feeding sites.
Swainson's Warbler
Limnothlypis swainsonii
Shy and difficult to see in deciduous forest with dense understory, often near water. Plain buffy-brown coloration with rufous crown and dark eyeline. Also note disproportionately large, sharp, pinkish bill and pink legs. Shimmies tail side-to-side as it slowly forages on the forest floor, investigating fallen leaf litter for insects. Fairly restricted breeding range in the southeastern U.S.; winters primarily on the Yucatan peninsula and in the Caribbean. Listen for loud, sweet song, similar to Louisiana Waterthrush but without the complex ending.
