Speckle-chested Piculet
Picumnus steindachneri
Tiny woodpecker restricted to a small area of the Andes in northern Peru. Combination of dark breast marked with white spots and heavily barred belly separate it from other piculets in the region. The male has red streaks on the forecrown. Inhabits epiphyte-laden cloud forest and often found with mixed flocks moving through the canopy. Song is a high-pitched trill.
识别特征
The speckle-chested piculet is 9 to 10 cm (3.5 to 3.9 in) long and weighs about 10 g (0.35 oz). Adult males have a black cap with a red patch on the forehead and white spots on the rest of it. Their upperparts are grayish brown whose feathers have pale gray edges and dark marks near the end that give a scalloped appearance. Their rump is paler. Their flight feathers are brown with pale gray or off-white edges on the secondaries and tertials. Their tail is blackish; the innermost pair of feathers have mostly white inner webs and the outer two pairs have a white patch near the end. Their chin and throat feathers are white with black tips. Their breast is black with large teardrop shaped white spots, and their belly and undertail coverts are white with wide black bars. Adult females are identical but with small white spots instead of red on the forehead.

分布与栖息地
The speckle-chested piculet is endemic to a very small area of Peru. It is known only from the central Huallaga Valley and certain parts of the Utcubamba Valley in the foothills of the eastern Andes. Other nearby areas with similar habitat have not been explored so the species' range possibly is larger. It mostly inhabits humid lowland primary forest and montane forest with vines, epiphytes and bamboos, but it also occurs in mature secondary forest. In elevation it ranges between 1,000 and 2,300 m (3,300 and 7,500 ft).

行为
The speckle-chested piculet apparently forages mostly in the forest canopy but also has been observed feeding at lower levels as well. It feeds alone, in pairs, or in small family groups and often joins mixed-species foraging flocks. Its diet has not been studied but is assumed to be mostly insects.<p>Juvenile speckle-chested piculets have been noted in late August and early September but nothing else is known about the species' breeding season, nest, eggs, or the rest of its breeding biology.<p>The speckle-chested piculet's song is "a high-pitched, rapid, falling trill: tree'e'e'e'e'e'e." Its "vigorous tapping during foraging can produce a distinctive rattling sound."

Imperial Cormorant
Leucocarbo atriceps
Very striking cormorant readily identified by white neck. Locally common black-and-white cormorant of colder coastal waters. Often seen perched on inshore rocks and jetties, sometimes with Magellanic Cormorant. Nests colonially on low islands (rarely in lakes inland from coast) and jetties. Plumage varies regionally, with some birds black-faced and others white-faced; the two types breed together locally in the Strait of Magellan. Immature resembles adult but plumage duller overall, brownish above.
Orchard Oriole
Icterus spurius
Small, slender oriole. Adult males are a unique rich chestnut-brown color with a black head. Females are dull yellow-green with white wingbars. Immature males are similar to females, but with a black throat and mask. Breeds in open woodlands, river edges, pastures with scattered trees, and brushy orchards. Visits feeders with nectar and fruits. Departs breeding grounds early and heads to wintering grounds in Mexico and Central America, where it can be found in any open or wooded habitat. Compare with female Hooded Oriole, which is larger and longer-tailed and has a narrower, more curved bill.
Fulvous-dotted Treerunner
Margarornis stellatus
A uniquely-marked little Furnariid. Very uncommon in restricted range on the west slope of the Andes in Colombia and Ecuador. Mostly bright orange-rufous with a dazzling white throat that bleeds down into bold speckles on upper breast. Singles or pairs forage with mixed-species flocks, usually hitching along mossy branches in the middle to upper levels. Occurs in humid mossy forest from around 1,200–2,200 m, typically at lower elevations than Pearled Treerunner.
