Red-legged Partridge
Alectoris rufa
Distinctive gamebird of farmland, grassy fields, and open heathland. Seen mainly as pairs and small groups, often along the edges of fields. Plumage is ornate and handsome, with a red bill, white throat, black streaked necklace, boldly barred flanks, and buffy belly. Other similar species (such as Chukar) do not overlap in native range, but can escape from collections or be introduced for hunting; all lack the diagnostic black-streaked necklace of Red-legged. Song is a dry, rasping “wa-cha-cha-wa-cha-cha” or “wi’ch-ch’ch.”
识别特征
Adult red-legged partridges are sandy-brown above, pinkish-buff on the belly, and pale grey on the breast, with a prominent gorget of black streaking, bold rufous and black flank-bars, a cream throat, pink legs, and a red bill and eye ring.<p>The crown and upper nape of adult red-legged partridge are a warm pinkish-brown; the fore crown and lateral edges of the crown are pale blue-grey, and the bird has a narrow off-white supercilium running from above the lores to the sides of the lower nape. The lores have a solid bar of black feathering above a patch of pinkish-red skin. This black colouration continues behind the eye, where it broadens, and then extends down around the throat-patch to meet the upper edge of the gorget. There is a patch of pale buff-brown feathering on the ear-coverts, adjoining the black. The eye is surrounded by a bright red eye-ring.<p>The chin and upper throat are creamy-white, and are bordered behind and below by a solid black gorget. The black colour continues down onto the lower throat as a patch of broad triangular black streaks on a pale sandy-grey background. Similar, but narrower, black streaks are present on a pale blue-grey background on the upper neck-sides, while the lower neck-sides are warm pinkish-brown. The breast is pale blue-grey, and the belly pinkish-buff. The flanks are marked with bold bright rufous-brown bars, typically between eight and ten; each bar has a narrow black leading edge, the background colour is off-white in front of each bar, and pale grey behind. The upper parts are plain, unmarked dark sandy-grey. The uppertail-coverts are similar in colour, and contrast with the pinkish-rufous tail-feathers.<p>The bill is bright red, the iris is medium brown, and the legs are pinkish-red.

分布与栖息地
This partridge breeds naturally in southwestern Europe (France, Iberia and northwest Italy). It has become naturalised in flat areas of England and Wales, where it was introduced as a game species, and has been seen breeding as far north as Sutherland. It is replaced in southeastern Europe by the very similar rock partridge (Alectoris graeca). It is a non-migratory terrestrial species, which forms flocks outside the breeding season.<p>This species breeds on dry lowlands, such as farmland and open stony areas, laying its eggs in a ground nest. They have been known to cohabit with wild rabbits.

White-streaked Antvireo
Dysithamnus leucostictus
Small antbird found inside cloud forest along the east slope of Andes and in Venezuela’s coastal mountains. Male is black with small white spots on wings that usually form parallel lines; faint streaking on breast is almost impossible to see in the field. Female is very different, with chestnut upperparts and grayish underparts covered with broad, pale stripes. Inhabits forest understory. Usually heard before seen. Vocalizations include a rising and then falling series of notes, an abrupt churr, and a series of dry rattles.
Zimmer's Woodcreeper
Dendroplex kienerii
Medium-sized, slim woodcreeper with a longish tail and shortish bill. Note the whitish eyebrow. Has a streaked head and upper back. Breast streaks have a triangular shape and dark edges. Inhabits the interior of seasonally flooded forests and forests on river islands; forages at middle levels, often accompanying mixed-species flocks. Sings a fast trill: “tr’r’r’r’r’r’r’r’r’r’r.” The similar, commoner Straight-billed Woodcreeper has a straighter, paler, and thicker bill, shorter tail, and slower song.
Whiskered Treeswift
Hemiprocne comata
Elongated white “whiskers” and brows give this elegant species the appearance of a wise old man. Long-tailed and long-winged, like a cross between a swift and a swallow. Glossy brownish-olive with glossy blue-black wings and head. Male has chestnut ear patches, while the female has bluish ones. Sallies from exposed perches in the canopy and along clearings in lowland and foothill wet forests. Gives squeaky, excited-sounding calls and high-pitched chattering.
