Wing-barred Seedeater

Sporophila americana

Small seed-eating bird with a thick black bill. Male strikingly black-and-white, with much variation in extent of black breastband and white wingbars. Averages darker at western end of range (Ecuador and Peru), paler along coast of northeastern South America. Separated from other black-and-white seedeaters by dark bill, white throat and collar imparting cowled appearance. No known range overlap with similar Variable Seedeater. Females nondescript brown and very difficult to distinguish from other seedeaters, sometimes best left unidentified. Look for thick black bill with curved culmen. Found in disturbed habitats including pastures, river edges, and scrubby weedy areas. Usually in pairs or small flocks, sometimes mixed with other seedeater species.

Adult males have a relatively heavy black bill. The upperparts are black, except for a greyish rump (actually white finely streaked black, but only visible up-close) and two distinct white wing-bars (the lower often reduced). The underparts are white, except for a broad black pectoral collar (sometimes reduced and incomplete) and blackish mottling to the upper flanks. The far duller female has a brownish bill, dull buffy-olive upperparts and pale olive-ochre underparts. Juveniles resemble adult females.

行为

It is found in open or semi-open grassy areas and shrub, usually in pairs or small flocks. As with other Sporophila seedeaters, it mainly feeds on seeds, but has also been observed taking flowers, buds and fruits.<p>It remains fairly common in Suriname, French Guiana and parts of Brazil, and is therefore considered to be of least concern by BirdLife International and IUCN. It is rare to uncommon in Venezuela and Guyana where threatened by trapping for the wild bird trade.

Anthracothorax prevostii

Large, bulky hummingbird with slightly arched black bill. Favors forest edge and open areas with scattered tall trees. Often perches and feeds high in canopy, but also feeds low on occasions and will visit feeders. Male (some females similar) solidly dark, deep green overall with black throat, purplish tail. Female and immature have broad dark stripe down center of throat and breast, white tail corners. Immature also has rusty mottling along sides of throat and breast.

Common Potoo

Common Potoo

Nyctibius griseus

Strange nocturnal bird like a mix between an owl and a nightjar. Large head and huge yellow eyes. Overall grayish-brown with splotchy patterning. Black mustache stripe helps distinguish from Great Potoo, along with smaller size. Spends the daytime perched on the end of a snag, where it blends in perfectly and becomes very difficult to spot. At night, hunts mainly for flying insects from an exposed perch. Found in open forested habitats with scattered trees, such as forest edges, along rivers or roadsides, or even in disturbed patchy woodland. Listen for mournful series of whistles, descending in pitch: “POO, POO, Poo, poo, poo.”

Golden-browed Chat-Tyrant

Golden-browed Chat-Tyrant

Silvicultrix pulchella

Small, attractive flycatcher found in humid forest along the east slope of the Andes. Eyebrow is thick and yellow at the base of the bill, becoming thin and white behind the eye, and it also has bold, rusty wingbars. Similar to wing-barred races of Crowned Chat-Tyrant, but white part of eyebrow is shorter and thinner. Also very similar to Jelski’s Chat-Tyrant, but yellow part of eyebrow is slightly larger, and the two species are not known to overlap. Inhabits forest understory and easy to overlook if not vocalizing. Typical song is a high, fast trill that briefly goes up in pitch before steadily descending.
