Fine-barred Piculet
Picumnus subtilis
Small, pale piculet. Light tan below, olive-brown above, with a black-and-white speckled crown; males have a red crown patch. Found in secondary forest, usually where there is dense understory, often bamboo, with emergent trees. Listen for its distinctive song, a descending series of 5-8 very high pitched notes (more notes than any other piculet in its range).
识别特征
The fine-barred piculet is about 10 cm (3.9 in) long and weighs about 10 to 11 g (0.35 to 0.39 oz). Adult males have a black crown and nape with wide reddish orange tips on the feathers of the forecrown and white spots on the rest. Their face is mostly light brown with some gray and whitish vermiculation. Their upperparts are yellowish olive with olive inclusions that give a faintly barred appearance. Their flight feathers are dusky brown with olive yellow edges on the secondaries. Their tail is black; the innermost pair of feathers have white inner webs. Their chin and throat are dull white. Their underparts are gray with straw yellow tips and bars. Their iris is brown, the beak black with a blue-gray base to the mandible, and the legs olive with a green tinge. Adult females are identical but with white spots on the whole crown and no red. Juveniles have a brownish black to sooty black crown with wide off-white to buff streaks, and their upperparts are more heavily barred than adults'.
分类信息
The fine-barred piculet is monotypic. Some authors consider it and the plain-breasted piculet (P. castelnau) to be sister species and they might hybridize.

分布与栖息地
The fine-barred piculet was long thought to be endemic to southeastern Peru but since about 2009 is also known from Acre state in far western Brazil though there appears to be a gap between the areas. In Peru it is best known along the upper Ucayali River; the Brazilian records are along the Purus River. Both are tributaries of the Amazon. In Peru it mostly occurs in primary forest along rivers but also in nearby secondary forest. In Brazil it occurs at the edges of terra firme forest in areas heavy with Guadua bamboo. In elevation it reaches as high as 1,100 m (3,600 ft).

Nothing else is known about its breeding biology.<p>The fine-barred piculet's song is "a descending series of sharp, high notes (generally about 7): SEE see see see see see see."

Indian Pied Starling
Gracupica contra
This sharply attired black-and-white starling has a pointed yellowish bill with an orange base. Mainly black upperparts with white belly and white rump noticeable in flight. Note the bare, deep orange patch around its eye that contrasts with its white cheek. Easternmost birds have a white, streaked forehead. Seen in loose flocks close to human habitation feeding on human refuse. Garbage dumps, damp grazing lands, and well-watered parks are its favoured haunts. Noisy with a variety of calls that includes mimicked sounds of other birds.
Violet-green Swallow
Tachycineta thalassina
A relatively small swallow of western North America. Adult males have a white face and show turquoise-green upperparts and a purple rump in good light. Females and immatures are duller on the upperparts, sometimes just dusky-gray. In flight, note the prominent white "saddlebags" extending up from the underparts to the sides of the rump. Fairly common in a variety of open habitats, often foraging over meadows or ponds. Can be seen in large flocks, sometimes mixed with other species of swallow. Breeds as far north as Alaska; winters primarily in Mexico and northern Central America.
Black-collared Bulbul
Neolestes torquatus
Odd, striking bulbul that resembles a shrike. Crown and shoulders are gray, back and wings are olive, and a broad black stripe runs from the beak, through the eyes and ears, forming a broad necklace on the creamy white underparts. Juvenile is less striking, with pale tips to the feathers. Pairs are localized residents in wooded tall grassland with scattered shrubs. Gives a fast high-pitched whiny “chet-cherit-rit-rit-rit” and a liquid melodious song that wafts up and down in pitch, rendered “choo-oo-cheloo-eo-loo-oe-loo”, sweeter than similar sounding Common Bulbul.
