Strickland's Woodpecker
Leuconotopicus stricklandi
Medium-sized woodpecker of high elevation pine and pine-oak woods endemic to central Mexico. Smaller than Hairy Woodpecker, which often occurs in the same areas; no range overlap with Arizona Woodpecker. Told from Hairy Woodpecker by big dark cheek spot on white face, dark brown (not blackish) upperparts with dark bars on white back patch, and extensive dark streaking and spotting on the underparts.
识别特征
Strickland's woodpeckers grow to be about 7 to 8 inches in length, and are mainly brown and white in color. They are brown on top with a dark rump and have white underparts speckled with many brown spots. Strickland's woodpeckers usually have three white bars on their wings, and have two white stripes across their face which join with another white bar on their neck. Male Strickland's woodpeckers also have a red patch on the nape of their head which is lacking on females.<p>The nest of this species is in a cavity excavated from a dead tree trunk. The female lays three to four white eggs on a bed of wood chips, but other details of nesting periods and duration are mostly unknown.

Strickland's woodpecker was first described by the French ornithologist Alfred Malherbe in 1845 and given its current name which commemorates the British scientist Hugh Edwin Strickland. Some taxonomic authorities, including the American Ornithological Society, continue to place this species in the genus Picoides.

Natterer's Slaty-Antshrike
Thamnophilus stictocephalus
Fairly small antshrike with a graduated, white-tipped tail. Males are gray overall with a black cap and a whitish center to the belly. Females have a cinnamon cap and back and are gray-buff below. Found in the lower levels of short transitional deciduous forests and white sand forests, avoiding humid forests. Sings a series of up to 20 clear notes, starting slowly and accelerating toward the end, finishing with a rattle. Very difficult to distinguish from the male of the Amazonian Antshrike, but differs in habitat. Female Amazonian Antshrike has a bright cinnamon head, not just the cap.
Peacock Coquette
Lophornis pavoninus
Tiny hummingbird of tepui highlands. Both sexes distinctive: males have long cheek tufts with black spotting, while females are heavily streaked below. Both have a white rump band like other coquettes. Found only in humid forest and scrub in the tepui region. Feeds on nectar by infiltrating territories of larger hummingbirds; also presumably eats tiny insects. May be seen resting on exposed perches. Both sexes are darker than other coquettes in range, and this species typically occurs at higher elevations than others.
Snares Snipe
Coenocorypha huegeli
A small, stocky wader endemic to New Zealand. Dark brown and black, with barred feathers on the belly. Native to on the Snares Islands, but introduced to Putauhina and Codfish Islands. Found in areas with dense vegetation cover, but will move into less covered areas at night to feed. Rarely flies. Male call is a “chup chup chup” sometimes building to a “queeyoo queeyoo queeyoo.”
