Black Oropendola
Psarocolius guatimozinus
Distinctive large oropendola with a small range from eastern Panama into Colombia. Overall black with dark chestnut on back and wings. It has an orange-tipped bill with large patch of blue skin at the base. Sexes similar. Found in pairs or small groups in the canopy or subcanopy of lowland forest and edge up to 800 m elevation. Often found along rivers. Like other oropendolas, builds large hanging nests. Recalls Montezuma Oropendola but no range overlap; also compare with rare Baudó Oropendola, which has pink (not blue) patch on the face.
识别特征
The male black oropendola grows to a length of about 46 cm (18 in) and the female about 39.5 cm (15.6 in). The sexes are similar in appearance and are mainly black, with dark chestnut back, rump, part of the wing-coverts and crissum (the area around the cloaca). There is a bluish bare patch on the cheek, edged with pink at its lowest extremity, and an orange-tipped, black beak.

Its altitudinal range is up to about 800 m (2,620 ft).

行为
The habits of the black oropendola have been little studied but its diet probably includes insects, small vertebrates and fruit. It clambers about high in the canopy and may sip nectar from flowers. It nests colonially, with up to twenty birds constructing their nests in one tree. The eggs are pale pink, scantily blotched with reddish brown. The black oropendola is probably polygynous, with one male mating with many females. The breeding season in Panama is February while in Colombia it is April to June.

Asian Dowitcher
Limnodromus semipalmatus
Very uncommon large, long-billed shorebird, nearly the size of a godwit, found in coastal mudflats and open marshes. Breeding adult extensively brick-red below, dark and strongly marked with brick-red tones above. Nonbreeding adult grayish brown with a duller, browner bill. Juvenile dark above, with broad gold feather edges, pale below, washed with warm buff or gold tones and with neat dark stipples and chevron-shaped marks. Blackish legs distinguish Asian from Long-billed Dowitcher, which has yellowish-green legs. Blackish or brownish bill of adult Asian differs from bicolored bill of godwits; note that bill of juvenile Asian has pale base.

Singing Bushlark
Mirafra javanica
A small, stocky, pale brown bird with a fairly heavy bill. Unlike other bushlarks, breast streaking is minimal and often only restricted to the sides of the breast, while the wings are not as rust-colored. The pale eyebrow is well marked and typically extends neatly down around the cheeks. There is subtle though considerable geographic variation over the huge range. The overall coloration can vary from dark gray-brown to rich rufous-brown to pale sandy, and the amount and clarity of streaking on the breast also varies. Found in dry, open plains, agricultural areas, open shrubland, and grassland. The song is varied and complex, and includes whistles, trills, buzzes, metallic notes, and sometimes imitations of other bird species. The song can be given from a perch or on the wing. Forages on the ground, where it can be hard to detect until very close; gives a loud chip as it flushes. Similar to Indian Bushlark, but Singing Bushlark has a white outermost tail feather, appears drabber overall, and looks chunkier. Larger-billed but smaller overall than Eurasian and Oriental Skylarks, and averages more darkly streaked on the back.

Pine Warbler
Setophaga pinus
A medium-sized, rather robust and long-tailed warbler, with a noticeably stout bill. Variable plumage, from bright adult males with extensive yellow throat to extremely dull grayish-brown immature females. Always look for two white wingbars, diffuse streaking on the sides of the breast, large bill, and long narrow tail with a shallow notch. Well-named: almost always found in pine trees throughout the year. In spring and summer, listen for loud musical trill (compare with Chipping Sparrow and Dark-eyed Junco). Occasionally visits feeders, especially for suet. A short-distance migrant, wintering entirely in the United States.
