Picumnus temminckii
Tiny woodpecker, found mostly in light woodlands and at forest edges. Note the short bill, black tail, and white central bar.

识别特征
The ochre-collared piculet is 9 to 10 cm (3.5 to 3.9 in) long and weighs 10 to 12.5 g (0.35 to 0.44 oz). Adult males have a black cap with red tips on the forehead feathers and small white spots on the rest of the cap. Their face is mostly rich buff-brown with a white stripe behind the eye. Their hindneck has the cinnamon-buff collar that provides its English name. Their upperparts are brown, sometimes with very faint paler bars. Their flight feathers are dark brown with narrow buff edges. Their tail is blackish; the innermost pair of feather have mostly white inner webs and the outer two pairs have a white patch near the end. Their chin and throat feathers are pale buffish white with narrow blackish edges. Their underparts are mostly whitish with buff on the flanks and lower belly. Their iris is brown, the orbital ring grayish, the bill black with a grayish base, and the legs grayish. Adult females are identical but for no red on the forehead. Juveniles are duller and darker than adults and have heavier but more diffuse barring on the underparts.
分类信息
The ochre-collared piculet is monotypic. However, the species' taxonomy and that of genus Picnumnus in general are uncertain. The ochre-collared piculet is closely related to the white-barred piculet (P. cirratus) and the ocellated piculet (P. dorbignyanus) and at times these species have been treated as synonymous.It frequently hybridizes with the white-barred piculet and occasionally with the white-wedged piculet (P. albosquamatus).

分布与栖息地
The ochre-collared piculet is found from southeastern Brazil's São Paulo state south through eastern Paraguay into northeastern Argentina's Misiones Province. It mostly inhabits lowland rainforest with bamboos, vines, and tangled growth, but it is also found in secondary growth, thickets, tall scrub, and parks and gardens. In elevation it ranges from sea level to 800 m (2,600 ft).

行为
As far as is known the ochre-collared piculet is a year-round resident throughout its range.<p>The ochre-collared piculet forages on thin branches, usually low in the forest. Its diet has not been well studied but is known to include ants and insect larvae.<p>The ochre-collared piculet's breeding season appears to include at least October through December. One nest in São Paulo State, Brazil, was a hole 2.5 m (8 ft) above the ground and a male was seen attending it. Nothing else is known about the species' breeding biology.<p>One ochre-collared piculet vocalization is a "[h]igh-pitched whistle, 'tsirrrr, si-si-si...'." Another is "a dry, toneless trill 'trrrrrruh'."

Olive Honeyeater
Lichmera argentauris
A nondescript sparrow-sized songbird with a slender, downcurved bill. Entirely olive-green above and uniform pale gray below, but note head pattern, which includes a prominent whitish smudge on the cheeks and dull bare skin below the eye. Juvenile has a pink facial patch. Singles, pairs, or groups inhabit scrubland, wooded areas, and coconut plantations in lowlands. Confined to islets in the Moluccas and to West Papua, where it is readily identified by its head pattern. Harsh, squeaky vocalizations include “tchew” and “grrt” notes and “chi-witchoo” or “witch-oo” phrases.
Littoral Rock-Thrush
Monticola imerina
Chunky, mid-sized robin-like bird. Males are pale gray and orange, while females are gray-brown. Madagascar endemic that is found in coastal spiny forest and scrub in the southwest. Perches up conspicuously. Song is a variable mix of thin whistles and raspy notes. Paler than Forest Rock-Thrush, with little or no overlap in range. Female similar to female Madagascar Magpie-Robin, but smaller and grayer, without white patch in the wing.
Channel-billed Toucan
Ramphastos vitellinus
Large toucan, widespread across South American lowlands. Mostly black with a dark bill (although some populations have a yellow ridge on top of the bill). Significant plumage variation across range: throat color varies from white to orange; bare skin around eye varies from blue to red. In the western part of its range, appearance is very similar to White-throated Toucan, but note voice: a grating croak, not a clear yelp. Singles, pairs, or small flocks are found in the forest canopy, often around fruiting trees. Named for the groove along the upper part of the bill, which is difficult to see in the field.
