Lemon-throated Barbet
Eubucco richardsoni
Small, colorful barbet of lowland rainforest canopy. Plumage variable across its range: males are typically green-olive above and bright yellow below, with a crimson crown and sides of the face (but crimson replaced with black in northeastern Peru and adjacent northwestern Brazil) and variable amounts of orange on breast; females are similar but duller, often with more gray in the head. Usually found near water, around oxbow lakes, forest streams, and swampy forest; also found in secondary forest and forest edges. Frequently associates with mixed species flocks. Listen for its low, rolling song.
Identification
The "lemon-throated" barbet is approximately 15.5 cm (6.1 in) long and weighs 24.5 to 34 g (0.86 to 1.20 oz). The male of the nominate subspecies has a red crown, gray-blue nape, and green upperparts. Its throat is yellow, the breast orange-red, and the belly and flanks greenish with dark streaks. The female is duller, with a gray-green crown, nape, and upperparts. Its throat is bluish, the breast orange-gold, and the underparts bluish yellow with dark streaks. The male E. r. nigriceps has a black crown and both sexes have blue-green upperparts.<p>The "flame-throated" barbet is 14.5 to 15.5 cm (5.7 to 6.1 in) long and weighs 26 to 42 g (0.92 to 1.48 oz), heavier than the two "lemon-throated" subspecies. E. r. aurantiicollis differs from the nominate by having a yellow nape, upperparts that are a yellower green, a more orange throat, and a redder breast. The female is similar to the nominate but less yellow in the throat and breast. The E. r. purusianus male is paler than the nominate and more pinkish on the breast. The female's breast band is the same orange-gold as the nominate's but narrower.
Taxonomy
The lemon-throated barbet as recognized by the South American Classification Committee of the American Ornithological Society (AOS), the International Ornithological Committee (IOC), and the Clements taxonomy has four subspecies: the nominate Eubucco richardsoni richardsoni, E. r. nigriceps, E. r. aurantiicollis, and E. r. purusianus. Clements groups richardsoni and nigriceps as "lemon-throated" and the other two as "flame-throated" within the species. The Cornell Lab of Ornithology's Birds of the World treats the two groups separately within its account of the lemon-throated barbet sensu lato. At various times, including as recently as 2014, aurantiicollis has been treated as a separate species called flame-throated barbet.

Range and habitat
The lemon-throated barbet is a bird of the western Amazon Basin. The four subspecies are found thus:<p>All of the subspecies inhabit the same forest types, lowland terra firme and dense secondary forest and their edges and clearings. They also are found in the edges of várzea forest. They are more numerous in maturing forest near rivers and lakes than in fully mature forest. In elevation they range from the lowlands to 1,375 m (4,511 ft) in Colombia, 1,200 m (3,900 ft) in Ecuador, 1,100 m (3,600 ft) in Bolivia, and 1,000 m (3,300 ft) in Peru.

Behavior
The diet of the "flame-throated" barbet is fruits and arthropods, approximately evenly divided. It forages alone or in pairs from the canopy of the forest to within 5 m (16 ft) of the forest floor, but more commonly between 12 and 24 m (39 and 79 ft). It also frequently joins mixed-species foraging flocks. It spends more than one-third of its foraging time feeding on insects in dead leaf clusters. The "lemon throated" barbet's diet and foraging behavior have not been documented but are assumed to be very similar.<p>The "lemon-throated" barbet's breeding season appears to be from April to November though it may begin in February. Its nest and eggs have not been described. The "flame-throated" barbet's breeding phenology has not been studied, though its breeding season is believed to start earlier than that of the nominate subspecies.<p>The songs of the four lemon-throated barbet subspecies do not differ substantially. Their song is "soft double or usually triple 'hoo' notes in [a] fast, trill-like series" [1]. Its calls are "various grunts and snarls" [2].

Southern Martin
Progne elegans
Large swallow with pointed wings and slightly forked tail. Males are deep iridescent purple; females are also entirely dark, but are brownish below, with faint scaling. Migrates within South America; at some times of year, occurs with other very similar martin species, making identification difficult. Females lack the light belly of similar Purple and Gray-breasted Martins; males essentially indistinguishable from Purple Martin.
Red-throated Thrush
Turdus ruficollis
This eastern counterpart of the Black-throated Thrush also breeds in montane areas and winters in lower-elevation areas on average. Males gray above and white below, with a brick-red throat and supercilium. Female paler, with more streaking on the breast and light suffusion of red on the face. Streaky and drab young birds can be difficult to distinguish from Black-throated; chestnut outer tail feathers and orange suffusion to the throat area indicate Red-throated. In areas of overlap, beware hybrids that may show features of both species. Pleasant song is simpler than that of Black-throated, and is composed of fluty whistles and trills. Calls include typical “chekchekchek” and high, thin “tseee.”
Surucua Trogon
Trogon surrucura
Often draws attention to its presence by its song: an ascending sequence of “kwa” notes, similar to Green-backed Trogon, but faster. Two subspecies occur in Brazil, Paraguay, and northeastern Argentina with limited geographical overlap that vary in the color of the breast and eyering; the southern one has a red belly and eyering, while the northern one has a yellow belly and eyering. The males of both subspecies have a violet-blue head and breast, a green back, and a white undertail. Females have a dull gray breast and the undertail is gray with white tips. Found in the middle to upper levels of forests and woodlands.
