Curl-crested Aracari
Pteroglossus beauharnaisii
Heavy-billed small toucan of humid tropical forest. Forages in the canopy of mature rainforest, often in small groups, and sometimes with other species of aracaris. More diffuse facial pattern than other aracaris, with grayish crown covered with soft curls. Belly has a single red band. Not as vocal as other aracaris, but may be heard giving soft grunts and occasionally loud yelps, sounding rather raptor-like.
识别特征
The curl-crested aracari is 42 to 46 cm (17 to 18 in) long and weighs 164 to 280 g (5.8 to 9.9 oz). It gains its English name from unique curly, shiny, black feathers on the top of its head and nape; they resemble pieces of plastic or enamel. Males and females are alike except that the female has a shorter bill. Their bill has a brown-orange line at its base. The mandible is ivory becoming orangey at its tip. The maxilla has an orangey culmen and a maroon stripe along its lower part that is wider at the base. Between them the maxilla is green or bluish. It has indistinct ivory colored "teeth" along the tomium. Bare blue skin surrounds their eye, and their cheeks and throat are whitish with black speckles. Their upper back and rump are red and the rest of their upperparts are dark green. Their underparts are yellow with a wide red band across the lower breast. Their undertail coverts can have a red wash. Immatures are a duller version of adults.
分类信息
The curl-crested aracari was first described by Johann Georg Wagler in 1831 but the spelling of its specific epithet was not corrected until 2020. It had at times been placed in the monotypic genera Beauharnaisius and Ulocomus.<p>The curl-crested aracari is monotypic.

分布与栖息地
The curl-crested aracari is found in the southwestern Amazon Basin south of the Amazon River. Its range extends from northern Peru south of the Marañón River east into western Brazil to the Madeira River and southeast to the Xingu River. From Peru the range also extends south into northern and central Boliva and into Brazil as far as northern Mato Grosso. It inhabits the interior, clearings, and edges of wet forest both well-drained and swampy. It mostly occurs at elevations below 500 m (1,600 ft) but is found as high as 900 m (3,000 ft) near the Andes.

行为
The curl-crested aracari apparently makes short-distance or local movements but is otherwise a year-round resident.<p>The curl-crested aracari usually forages in groups of up to 12 individuals, and usually in the canopy. It does feed at fruiting bushes near the ground. Its diet has not been detailed but is known to be mostly fruit. Its diet also includes eggs and young of other birds, and it is known to tear apart the nests of yellow-rumped caciques (Cacicus cela) to obtain them.<p>The curl-crested aracari's breeding season appears to be mostly May to August but it may start earlier and extend longer. Its nest, eggs, and the rest of its breeding biology are not known.<p>The curl-crested aracari's calls include series of "deep 'rrek' notes, soft 'rrr' to hard, even grunting 'grenk' notes". It also makes a "softer 'et-et'" when settling into a roost. Another author adds a "low, raucous 'cha-cha-cha cha wruh cha--'."

Congo Moor Chat
Myrmecocichla tholloni
An unusual and distinctive Central African chat. Mostly gray-brown with a white throat, rump, and undertail and white wing patches that are conspicuous in flight. Found locally in grassland, usually in pairs or small groups. Hops along the ground or sits up on low perches. Structure and behavior similar to Sooty Chat, but gray-and-white plumage is completely different. The cheerful song alternates higher whistled notes and lower chirruping notes. This song is often given in a hovering display flight.
Ultramarine Lorikeet
Vini ultramarina
A mostly blue-and-white lorikeet with a bright ultramarine upperside and darker blue thighs, chest band, and crown. Chest, throat, cheek, and belly are white with dark flecking. Unique within its range. Common call is a high-pitched buzzing “tzeet.”
Black-throated Blue Warbler
Setophaga caerulescens
Striking warbler with vastly different male and female plumages. Males are unique deep blue above with black face and sides and white belly. Females are plain brownish-olive with dingy buffy underparts and subtle face pattern. Always look for small white patch on the wing, lacking only on the dullest immature females. Breeds in the understory of mixed forests, favoring hills with dense vegetation. Found in nearly any wooded or shrubby habitat during migration. Winters primarily in the Caribbean. Listen for lazy buzzy song, usually a series of notes with a final long buzz.
