Rufous-crested Coquette
Lophornis delattrei
Tiny hummingbird; male is striking with fabulous spiky orange crest, each feather tipped in black. Otherwise greenish with dark throat and conspicuous white band across rump. Female much less obvious; look for very small size, rufous forehead and throat, and white band across rump. Range usually helps to eliminate other similar species of coquette; note especially similarity to Spangled Coquette. Found more often in edges than other coquettes, especially brushy clearings or roadsides with flowering bushes.
识别特征
Rufous-Crested Coquettes are of 6.4 cm to 7.0 cm in length, have a wingspan of 4.0 cm to 4.5 cm, and have weigh an average of 2.8g. This species has a short orange bill that ends in a sharp blackened point. Its back and stomach is a light iridescent green. A band of white feathers crosses the rump, and brown, orange, and green tail feathers extend posteriorly from it. The adult male has a crest of slender and rigid black tipped rufous feathers, that extend dorsally from its rufous coloured head feathers. It has a throat of darker iridescent green feathers which ends posteriorly in small pointed white feathers. A vertical band of rufous feathers frames the green throat and tail feathers of the males, and the tail ends in a double-rounded shape. Female rufous-crested coquettes share a similar physiology to the males, with a few key defining differences. Females display no head crests, and instead their rufous coloured forehead feathers fade into the iridescent green ones which extend down their backs. Their throats are not uniformly green, but instead are primarily white with small clusters of green feathers. A band of rufous feathers extends fully from the side of the throat up to the forehead. The tail of the female rufous-crested coquette is singly rounded, and the tail feathers, while primarily green, end in small patches of light orange.
分类信息
The rufous-crested coquette is a bird in the family Trochilidae, which includes all extant species of hummingbirds. It is a member of the genus Lophornis, which was identified first by the French naturalist and surgeon René Lesson in 1829, and includes a number of extremely small hummingbirds distributed across central and south America. The rufous-crested coquette was identified by Lesson in 1839, and is thought to be closely related to the tufted coquette.<p>An extremely similar species of coquette is endemic to a small region of Guerrero Mexico. This bird’s taxonomic classification is debated, and some ornithologists list it as the independent coquette species Lophornis brachylophus, but has also been classified as a subspecies of the rufous-crested coquette, L. d. brachylopha.

分布与栖息地
The species inhabits the Pacific and Caribbean mountainsides of Peru, Bolivia, Colombia, Ecuador, Panama, and Costa Rica; and at least one observation of the species has been reported in western Brazil. The species is primarily found in altitudes of 500m 1,900m above sea level, likely inhabiting higher altitudes when breeding and lower when not. Rufous-crested Croquettes favour humid forests with evergreen or semi-deciduous compositions, and travel large distances within these ecosystems in search of suitable foods. In a homing experiment with frilled coquettes, this genetically similar species was seen to navigate ranges of up to 15 km.

Reddish Egret
Egretta rufescens
An entertaining heron to watch—known for sprinting, jumping, and spinning around in shallow water with its wings held up. Dark morph is more common than white morph. Adults are dark gray with a rusty head and neck. Immatures are paler grayish and rusty overall. In breeding plumage, the pink bill and blue lores can become shockingly bright. White morphs are similar to other egrets, but note behavior, grayish legs, and pink bill base (adults). Found exclusively near the coast, especially on mudflats. Typically uncommon, usually seen singly or in scattered small numbers. Dark morph most easily confused with Little Blue Heron, but Reddish Egret is larger and forages much more actively.
Yellow Longbill
Macrosphenus flavicans
An unusual warbler with a long bill and yellow eyes. Brownish above and dull yellow below with a gray head and whitish throat. Found in rainforest, mainly in dense tangles at middle levels, usually in pairs or small groups. Similar in appearance to other longbills, but with a good view, separated by the coloration of the underparts. Most often detected by the distinctive song: a long series of clear whistled notes in which each note is slightly lower in pitch. The pattern is similar to that of Sabine’s Puffback, and the individual notes sound very batis-like.
Canada Warbler
Cardellina canadensis
Spiffy warbler found in boggy areas. Blue-gray above and yellow below with distinctive yellow spectacles and necklace of black streaks. Legs are pale orange. Females show fainter necklace than males. Typically found in low vegetation, especially wet woods and thickets. Nests on the ground. Feeds on insects. One of the longest-distance migrant warblers; winters in South America.
