Crescent-chested Puffbird

Cryptically plumaged puffbird. Brown overall with cinnamon streaks down the head, back, and wings. Note the distinctive black-and-white breast band. Usually sites motionless in the understorey and middle levels of humid forests and second growth.
识别特征
The crescent-chested puffbird is 17.5 to 20 cm (6.9 to 7.9 in) long. The nominate M. s. striata weighs from about 40 to 47 g (1.4 to 1.7 oz); M. s. minor is smaller. The nominate's head and upperparts are blackish with buffy streaks. The face is rufous around the bill and has a buffy or white "moustache". The wing is brown with buffy markings; the tail is plain dark brown. The upper breast has a white crescent with a black band below it. The lower breast is rufous, the center of the belly whitish, and the sides of the breast and belly dull brown with buffy scallops. M. s. minor has a brighter breastband and its underparts are whiter without barring.
分类信息
The crescent-chested puffbird was for a time called Malacoptila torquata but since the mid-1900s it has borne its current binomial. The South American Classification Committee of the American Ornithological Society (SACC), the International Ornithological Committee (IOC), and the Clements taxonomy treat it as having two subspecies, the nominate M. s. striata and M. s. minor. However, BirdLife International's Handbook of the Birds of the World (HBW) treat those entities as separate species, the greater and lesser crescent-chested puffbirds respectively.

分布与栖息地
The crescent-chested puffbird's nominate subspecies is found in southeastern Brazil from Bahia and Minas Gerais south to Paraná and Santa Catarina. M. s. minor is found in a small disjunct range in Maranhão and Piauí states in Brazili's Northeast Region. The species inhabits a variety of semi-open landscapes such as the edges of humid lowland forest, logged forest, and secondary forest. It often occurs along roads and at the edges of clearings but rarely in the forest interior. In elevation it ranges from sea level to 2,100 m (6,900 ft).

Green-crowned Plovercrest
Stephanoxis lalandi
Medium-sized hummingbird with an iridescent green body and short bill. Males have a long iridescent green crest, a violet throat that extends down the belly, flanked in gray. The female has a less prominent crest, a gray belly, and a more prominent white spot behind the eye. Resembles Violet-crowned Plovercrest, but male Green-crowned Plovercrests have a green rather than violet-blue crest. Females of Green-crowned Plovercrest have slightly smaller white tips to the outer tail feathers. Found in the understory of lowland and montane forests and light woodlands.
Pirre Warbler
Basileuterus ignotus
This warbler has an extremely limited range near the border of Panama and Colombia. The head pattern is distinctive; look for the bold white eyebrow and reddish crown. Otherwise brownish overall, slightly paler below, with pink legs and bill. Sexes similar. Found in pairs in the understory of humid montane forest from around 1,200–1,650 m, sometimes following mixed-species flocks.
Red-throated Barbet
Psilopogon mystacophanos
Large emerald-green barbet with a heavy dark bill. Unlike many barbets, exhibits strong sexual dimorphism: male has yellow, black, blue, and red facial patches, while the female only has blue and red. Like other barbets, can be difficult to spot up in the canopy. Listen for its songs, an incessant series of gulping, concise hoots, or a string of trilling that eventually slows and lapses into hoots; notes have a “tapping” quality different from that of the more resonant Red-crowned Barbet. Inhabits all manner of forested lowland habitats, from primary tracts of forest to parks and gardens.
