Collared Puffbird
Bucco capensis
Distinctive medium-sized rainforest bird, easily recognized by large, mostly bright cinnamon head and orange bill, whitish underparts, and clean black band completely encircling nape and breast. Inhabits lower and middle levels of tall rainforest, sometimes up to the canopy, where it sits motionless before making sudden flights to bark, foliage, or ground for large insects and small vertebrates. Encountered singly or in pairs, but rather seldom seen due to lethargic behavior. Typically silent during the day; song—given well before first light—is a wild-sounding series of quavering notes that is unlike that of any other bird.
识别特征
The collared puffbird is about 19 cm (7.5 in) long and weighs 46 to 62 g (1.6 to 2.2 oz). Its head and back are dark rufous, the rump a lighter rufous, and the tail orange-chestnut with narrow black bars. The folded wing shows fine black barring on a brown background. The chin and throat are white to buffy white that extend around the nape as a thin buffy line. Below them are a wide black collar that encircles the chest and upper back. The lower breast and the center of the belly are buffy white that darkens to dull orange on the flanks and vent. The eye is surrounded by bare orange-yellow skin; the eye color can be whitish, orange, or vermilion. The bill is mostly orange with some dusky on the maxilla. The feet can be light green, orange, or brown.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the collared puffbird in his Ornithologie that was based on a specimen collected in French Guiana. He used the French name Le barbu and the Latin name Bucco. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the collared puffbird. Linnaeus included a terse description, coined the binomial name Bucco capensis, and cited Brisson's work. The specific epithet capensis denotes the Cape of Good Hope where Linnaeus mistakenly believed the birds occurred.<p>The collared puffbird is currently (2021) treated as monotypic. The population in the western part of its range has been suggested as a subspecies, Bucco capensis dugandi, but most authorities do not accept it.

分布与栖息地
The collared puffbird is found in most of the Amazon Basin, from southeastern Colombia south through eastern Ecuador and Peru to northern Bolivia and east through southern Venezuela, the Guianas, and northern Brazil. In Brazil it is found as far east as Belém and south into Mato Grosso. It inhabits humid primary terra firme forest, drier hilly country, and also várzea forest in the lower Amazon. In elevation it ranges from sea level to 1,700 m (5,600 ft) but is usually found below 1,000 m (3,300 ft).

行为
The collared puffbird hunts by sallying from a shaded perch to pluck prey from foliage, bark, or the forest floor. Its prey includes lizards, snakes, frogs, and several types of large insects. It sometimes joins mixed-species foraging flocks and less often follows army ant swarms.<p>The collared puffbird's breeding season spans at least May to September. It lays its two glossy white eggs in a cavity excavated in an arboreal termitarium or rotted tree trunk.<p>The collared puffbird's song is "a repeated, brisk, mewing 'cua-will, cua-will…' or 'awww awwAWW-chaw awwAWW-chaw awwAWW-chaw'", and is mainly given at or just before dawn. It is frequently sung as a duet.

Cinnamon-tailed Sparrow
Peucaea sumichrasti
Very local and often elusive sparrow endemic to the Isthmus of Tehuantepec. Found in brushy woodland and edge of tropical lowlands on Pacific slope. Usually in pairs or small groups, which keep in touch with high, rhythmic twittering choruses. Mostly stays low in brush or on the ground, but sings from atop bushes. Note the subtly distinctive face pattern with double dark whisker stripes, pinkish bottom bill, and long orangish tail.
Sooty-capped Babbler
Malacopteron affine
Bland, unremarkable-looking medium-sized babbler of open forest, forest edges, clearings, brushy riparian, and overgrown margins of cultivation in lowland and foothill areas. Extremely generic-looking, with no bright colors, a medium-length tail, and an average bill. Evenly-proportioned body gives it a rather bulbul-like outline. Note unmarked gray face, dark gray crown, dark rufous tail, and faint brownish wash on the chest. Especially similar to Moustached Babbler, but note present species’ darker crown, plain face (no moustache), and more slender bill. Scaly-crowned is also similar, but has a bright rufous patch on the forecrown. Plainly-colored Pellorneum babblers can be confusing, but note differences in proportions and profile. Most frequently-heard song is a beautiful but eerily human-like rising series of even whistles; when duetting, one bird often gives explosive “wik!” calls in response. Also gives a quicker, more cheery, and less human-like version of the song, as well as a short melancholy up-and-down series of whistles.
Napo Sabrewing
Campylopterus villaviscensio
Large, dark hummingbird found in cloud forest along the east slope of the Andes. Ranges from far southern Colombia south to northern Peru. Male has large blue patch on throat and breast, and a glittering green crown. Female has gray underparts; she is similar to Gray-breasted Sabrewing but has narrower white tail tips. Also note white spot behind eye. Infrequently encountered, though does visit feeders in some areas.
