Chestnut-capped Puffbird
Bucco macrodactylus
Attractive small puffbird of lowland rainforest. White below, reddish brown above, with a black mask and single black breast band. As with most puffbirds, can be difficult to spot as it sits motionless on a perch for long periods of time; usually perches fairly low, in the under and midstory in dense vegetation. Prefers forest edges and other areas of dense secondary growth, especially around water.
识别特征
The chestnut-capped puffbird is 14 to 16.5 cm (5.5 to 6.5 in) long and weighs about 25 g (0.88 oz). Its plumage is unique among puffbirds. Its crown is chestnut, its nape a bright reddish orange, and the rest of the upperparts brown with a few lighter bars on the back and many on the rump. The tail is long, narrow, and warm dark brown. It has a thin white supercilium, black cheeks and lower throat with a white line between them, and a reddish white chin and upper throat. The chin feathers curl up over the base of the bill. Below the black throat is a white band and the rest of the underparts are buffy with fine dusky barring except on the lower belly. The bill is black, the eye red to brown, and the feet brownish- to greenish gray.
分类信息
The chestnut-capped puffbird has variously been placed in genera Bucco, Argicus, and Cyphos. As of 2021, the International Ornithological Committee (IOC) and the Clements taxonomy place it in Bucco, while BirdLife International's Handbook of the Birds of the World (HBW) place it by itself in Cyphos. All three treat it as monotypic, though part of the Venezuelan population has sometimes been separated as B. m. caurensis.

分布与栖息地
The chestnut-capped puffbird is found in the upper Amazon Basin of southern Venezuela; eastern Colombia, Ecuador, and Peru; northern Bolivia; and western Brazil. It is found in many forest types but typically near water. Examples include terra firme and várzea forest, early successional and secondary forest, and gallery forest. It also occurs away from water in scrubby forest. It usually stays fairly low, from the undergrowth and understory to the subcanopy, and frequently perches within 6 m (20 ft) of the ground. In elevation it is usually found below 660 m (2,200 ft) but has been recorded as high as 1,000 m (3,300 ft) in Peru and once at 1,200 m (3,900 ft) in Ecuador.

行为
The chestnut-capped puffbird forages by sallies from a perch to pluck insects from vegetation. It has also been reported to take small vertebrates.<p>Almost nothing is known about the chestnut-capped puffbird's breeding phenology. One nest was a cavity in a termitarium about 2.5 m (8 ft) up in a tree.<p>The chestnut-capped puffbird's song is "a series of plaintive but abrupt rising notes ending in [a] twitter, 'pup pup pep pep peep peep pip pip pip piz'".

Superb Starling
Lamprotornis superbus
A chunky, short-tailed, colorful savanna starling. Note the white chest band, white undertail, and white patch on the underwing, conspicuous in flight. Immatures have a dark eye and lack a breast band, but are usually associated with adults. Found in a variety of dry or moderately moist habitats including savanna, woodland, thorn scrub, and villages, usually in small flocks, sometimes with other species of starlings. Similar to Hildebrandt’s and Shelley’s Starlings, but easily separated by the white breast band. The calls include a variety of scolds and squeals.
Hook-billed Hermit
Glaucis dohrnii
A range-restricted hermit with a gently curved bill. Dark green above and rusty below, with a prominent broad white eyebrow and a greenish tail with a white tip. Found in humid forests, where it forages in the understory, favoring Heliconia plants. The similar Rufous-breasted Hermit has a more strongly curved bill and a bronzy tail with a white tip.
