Rosy Bee-eater
Merops malimbicus
A nomadic and locally migratory bee-eater of rainforests, savannas, rivers, and glades, where it can be seen flying high overhead or perched high in trees. Distinctive, with long triangular wings, rosy pink underparts, a black eye-line, a clean white moustache, and evenly gray upperparts. Voice is similar to those of other bee-eaters, including hoarse “tik” and “trrp” calls. Nests in sandy riverbanks and sandbars, where colonies can comprise over 20,000 pairs.
识别特征
The adult is a distinctively colored bird that grows to a length of 22 to 25 cm (9 to 10 in) with tail-streamers adding 5 cm (2 in) to this, and weighing about 45 g (1.6 oz). Both sexes have similar features. The forehead and crown are dark grey, the mask black and the chin and cheek are white. The mantle is black, the wings and back are slate-grey and the rump paler grey. The tail is carmine, gradually bleaching to grey. The throat and underparts are bright pink and the undertail coverts are grey. The undersides of the flight feathers and large tail feathers are glossy black. The beak is black, the eye reddish-brown and the leg yellowish-brown. The juvenile is similar in coloring but paler, many of the smaller feathers having pale edges.
分类信息
English naturalist George Shaw first described the rosy bee-eater in 1806 as Merops malimbicus. This type of locality being from Malimbe, Cabinda in Angola. Molecular studies suggest that this species is most closely related to the white-throated bee-eater (Merops albicollis) and the northern carmine bee-eater (M. nubicus).

行为
Like other bee-eaters, the species feeds on insects that it catches by swooping from a perch or hawking in the air. It forages in various habitats; close to the surface of water bodies, over savannas and woodlands, as well as above the canopies of forests, sometimes ascending to considerable heights. A large part of their diet is flying ants, but these birds also feed on bees, butterflies, dragonflies, grasshoppers, flies and beetles. Foraging flocks may be very large and birds may dip into the water during flight to bathe. Nesting takes place on raised beaches and sandbars of large rivers exposed by falling water levels. Holes are dug with the feet and passages may be 2 m (7 ft) or so long. Only a few colonies are known but these may be very large, with estimated nest counts of 8,000 to 27,300 or more, and a density of about two nesting holes per square metre. The colony may nest in the same location the following year but the nests that have been inundated during the rainy season need to be re-excavated.

Copper-tailed Hummingbird
Saucerottia cupreicauda
This hummingbird is found in humid forest in mountainous regions of eastern Venezuela, the Guianas, and northern Brazil. Plumage is bright green with a coppery rump and tail, and belly ranges in color from pale gray to buff. Occasionally seen in lowlands, where it is perhaps just a seasonal visitor or wanderer. Formerly considered to be a subspecies group of Green-bellied Hummingbird.
Dark-brown Honeyeater
Lichmera incana
Mostly dull brown with slightly brighter olive wings and a grayish head. A pale buffy-white line runs below the eye to the base of the bill, which is dark and slightly decurved. Found in all habitats. Unlike any other honeyeaters in its range. Voice is most commonly a loud “tchoo-tchoo-tchoo” and a mixed warbling.
Black-vented Oriole
Icterus wagleri
Attractive oriole of the interior and highlands; some migrate in winter to Pacific coast lowlands. Favors scrubby woodlands and semiopen areas with tall hedges of flowering trees; also flowering coconut plantations on the Pacific coast. Usually in pairs; found as often apart from other orioles as mixed with them. Sexes alike: yellow breast has a distinctive, burnished orange tone. Upperparts appear wholly black when rump is covered by wings. Black vent area diagnostic on adult. Immature variable: note lack of wingbars, orange tones to yellow plumage, and rather long, straight bill.
