Carrizal Seedeater
Amaurospiza carrizalensis
Small, chunky finch with thick gray bill. Male deep blue-black, female brown, both sexes with white underwings. Mostly found in pairs in the understory of spiny bamboo forest. Song a fast musical warble of four or six notes “pee PEEu pee PEEu peePEEuu.” Similar to Blue-black Grassquit, which is smaller with a more conical bill; also to Amazonian Grosbeak, which is larger with a bulkier bill. Little known, endemic to the southern lowlands of Venezuela.
Identification
The Carrizal seedeater is 12 cm (4.7 in) long and weighs 12 to 14 g (0.42 to 0.49 oz). The male is a glossy dark slaty blue that is darker on the face and underparts. The female's upperparts are warm brown and the underparts yellow-buff, darker on the flanks.
Taxonomy
The Carrizal seedeater was described based on three specimens collected in 2001. The researchers who determined that it was a new species, Miguel Lentino and Robin L. Restall, named it Carrizal blue seedeater, but the "blue" was dropped by taxonomic organizations to avoid conflict with what was then the blue seedeater (Amaurospiza concolor).

Range and habitat
The specimens of Carrizal seedeater were collected on Isla Carrizal in the Caroni River of northern Venezuela. Construction of the Tocoma Dam, which began in 2006, flooded the island. The species has since been found elsewhere in the Caroni River watershed. It is known only from stands of spiny Guadua and Ripidocladus species of bamboo in deciduous forest.
Behavior
The crops of the Carrizal seedeater specimens contained beetles and vegetable matter.<p>No information has been published about the Carrizal seedeater's breeding phenology.<p>The Carrizal seedeater's song is "a pleasant whistled warble, 'sweet sweet pit-swee pit-swoo'" [1].

Cocoa Woodcreeper
Xiphorhynchus susurrans
Warm brown bird with buffy streaks on head and breast; hitches up tree trunks. Generally longer tailed and longer billed than a woodpecker. Very similar to many other species of woodcreepers. Focus on bill: long, fairly thick, and almost straight; generally pale grayish with fleshy tones, but darker on top edge. Listen for song, a long series of clear whistled notes fading slightly at the end. Found in wooded habitats, often in more open forest, edge, or second growth.

Buru Cuckooshrike
Coracina fortis
A relatively large gray songbird with a notably heavy bill, a prominent black mark between the bill and the eye, and a paler belly. Singles and pairs frequent the canopy of forest within lowlands and mountains, including degraded forest. Confined to Buru. Differs from Pale Cicadabird in its larger size and extensive black area between bill and the eye. Differs from Common Cicadabird in its pale belly, larger size, and heavier bill. Call is a short, sharp, slightly burry “skeet.”

Yellow-mantled Weaver
Ploceus tricolor
A neatly patterned weaver that stays high above the ground in forests and old farmland, often near flooded areas or water, in small groups or with mixed-species flocks. Black head and vent contrast with the dark gray or reddish belly. Upperparts are black except for a bright gold triangular patch on the back. Engages in a wide variety of foraging behaviors, including gleaning, flycatching, and hitching up larger branches and trunks in a woodpecker-like fashion. Occurs with several other species of weaver, but note Yellow-mantled Weaver’s distinct upperparts and the contrast between its black throat and vent and its paler belly. Calls include mechanical whistles and rasps and dry chatters, sometimes combined in complex songs.
