Brown-banded Puffbird
Notharchus ordii
Large, black-and-white puffbird with a brown breast patch. In addition to its brown band, note the lack of a white eyebrow, present in other black-and-white puffbirds. Found mainly in forests with sandy or rocky soil, often with stunted vegetation. In some parts of its range, it is also found in mature upland rainforest. Its song is a long, rising series of whistles, followed by a slowly descending series of stuttered whistles “wi wi woo, wi wi woo, …”.
识别特征
The brown-banded puffbird is about 20 cm (7.9 in) long and weighs about 51.5 g (1.8 oz). It crown, nape, upperparts, and a thin line from the gape to the eye are a slightly glossy black. The lower part of its forehead; its face, chin, throat and upper breast; and a thin white line at the base of the nape are white. A black band separates the white upper breast from the olive-brown lower breast. The central belly is white with brown spots and the flanks white with black spots. The upper side of the tail is black with white tips to the feathers and the underside has a white band at the middle. A white band on the underwing shows in flight. The large bill and the feet are black and the eye dark brown.
分类信息
The brown-banded puffbird is monotypic. It is closely related to the black-breasted puffbird (N. pectoralis) and some authors have proposed that they form a superspecies.

分布与栖息地
The brown-banded puffbird has a highly disjunct distribution. One large region spans from southern Venezuela's Amazonas state into northwestern Brazil's Amazonas state. Another region is in Brazil's Rondônia state and a third at the intersection of Brazil, Peru, and Bolivia. There are also scattered records elsewhere in Bolivia, Brazil, Colombia, and Peru. It inhabits the interior and edges of rainforest and transitional forest, stunted forest on white-sand soils, and the edges of terra firme forest. It tends to remain in the canopy.

行为
Little is known about the brown-banded puffbird's feeding behavior and diet. The few observations suggest that it hunts like others of its genus, sallying from a perch to catch insects or pluck them from vegetation.<p>The one described nest of the brown-banded puffbird was a cavity in an arboreal termitarium about 4.5 m (15 ft) up in a mostly bare tree; both sexes excavated it.<p>The brown-banded puffbird's song is "lengthy, with several clear, loud introductory whistles followed by cadenced couplets and triplets."

Tricolored Munia
Lonchura malacca
Small, finchlike bird of weedy and grassy areas in tropical lowlands. Often in small flocks, which associate readily with seedeaters and grassquits. Adult is handsome and striking with rusty upperparts. Black head and underparts are cut by a broad white swath from flanks across the lower breast. Note stout gray bill. Juvenile notably plain, buffy brown overall with stout bluish-gray bill. Note the pointed tail, unlike seedeaters and grassquits. Native to Asia and spreading in New World as an escaped cage bird.
Indian Yellow Tit
Machlolophus aplonotus
The only crested tit in most of its range. Black front with yellow cheek and yellow eyebrow. Yellowish-green upperparts, white-spotted wings, and yellow-and-black underparts. Females and juveniles are duller, with shorter crests, central stripe thinner and incomplete, and yellowish parts becoming dull white. A bird of the hills, it is most abundant between 500 meters and 1800 meters of elevation, but rarely descends to lower elevations. Seen in pairs or family groups, often joining mixed-species foraging flocks in the non-breeding season. Forages in the canopy, emitting loud whistles and harsh chatters.
Medium Ground-Finch
Geospiza fortis
One of the most common and conspicuous of the Galápagos finches. Bill is at least as long as the bill is deep, with the upper edge slightly rounded. Lower edge of bill is mostly straight. Bill is moderately stout-looking, but bill size varies between individuals, and not all birds can be accurately identified. Bill is black on breeding male and dull orange on female and nonbreeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are streaked with gray. Large Ground-Finch’s bill has bulbous appearance and usually forms a ridge where it meets the crown. Small Ground-Finch’s bill is smaller and more pointed. Found in a wide variety of habitats on most islands, but absent from Española and Genovesa.
