Buffy Hummingbird
Leucippus fallax
Medium-sized brown-and-green hummingbird. Upperparts pale green, underparts warm buff; bill medium-sized; has dull white spot behind eyes and boldly white tipped, rounded tail. Locally fairly common; territorial. Restricted to desert scrub, dry forest edges, and mangroves in northern Venezuela and extreme northeastern Colombia. Ruby Topaz female similar but with rufous tail and shorter bill.
识别特征
The male and female buffy hummingbird are similar in appearance but the female tends to be less brightly coloured, and there is considerable variation in shade between individuals. The back and upper parts of the bird are a dull green, the underparts pale cinnamon-buff and the belly and undertail coverts white. The tail is dull green with a transverse grey bar and a rounded end. There is a white spot behind the eye and the beak is slender and straight. The upper mandible is black and the lower one pale with a black tip. The bird ranges from 8.5 to 9 cm (3.3 to 3.5 in) in length.
分类信息
The hummingbird is a member of the class Aves, the order Apodiformes, the family Trochilidae and the genus Leucippus.<p>This genus formerly included additional species. A molecular phylogenetic study published in 2014 found that Leucippus was polyphyletic. To resolve the polyphyly the Tumbes hummingbird and the spot-throated hummingbird were moved to the resurrected genus Thaumasius.

White-cheeked Pintail
Anas bahamensis
Very distinctive duck with its white cheeks, throat, and tail contrasting with its brown body. The bill is dark with red sides at the base. In flight shows pale brown and green patches on the wings. Both sexes similar. Found in both fresh and saline wetlands.
Malayan Crestless Fireback
Lophura erythrophthalma
A rare, compact pheasant of damp tropical lowland rainforest, especially peat swamp forest. Dark overall with bright red facial skin and a cocked, vertically-flattened tail. Males have fine vermiculations on the wings, deep orange (fire)back, purple rump and pale orange tail. Females are dark blue all over. Exceedingly shy, typically moving in pairs or small groups. Female is similar to Salvadori’s Pheasant male but the 2 species do not normally co-occur and the latter has often has its tail pointing downwards. Gives a relatively high-pitch “chick!” followed by a low “takrow”.
Brown-billed Scythebill
Campylorhamphus pusillus
In typical woodcreeper fashion, this bird is mostly warm brown with streaks on the head and breast. Look for the notably long, extremely decurved bill. This species is easy to identify when it is the only scythebill in range, but in South America it overlaps with other scythebill species. Voice can be a good clue (Brown-billed usually stutters in its whistled series), and bill color can sometimes be helpful but often difficult to judge. Hitches up tree trunks much like a woodpecker. Most often seen following a mixed-species flock in the forest, sometimes in adjacent second growth.
