Chiribiquete Emerald
Chlorostilbon olivaresi
Poorly known hummingbird found only in the remote Chiribiquete Mountains in southeastern Colombia, far from the Andes. Male is iridescent green with a bluish tail. Female has pale underparts, black mask, and white stripe behind the eye. Very similar to the widespread Blue-tailed Emerald, but larger and longer billed. Inhabits scrubby areas in the higher parts of the mountains, and avoids dense forest.

分布与栖息地
The Chiribiquete emerald is restricted to the Serranía de Chiribiquete, a range of flat-topped mountains straddling south central Colombia's Guaviare and Caquetá departments. There it primarily inhabits the open scrub and savanna of the range's middle and upper elevations. It also occurs in the forest at somewhat lower elevations but shuns the lowlands that surround the mesas. In elevation it ranges between 800 and 1,600 m (2,600 and 5,200 ft).

African Gray Woodpecker
Dendropicos goertae
A mid-sized woodpecker with a yellow-green back and gray underparts. The crown is red in males and plain gray in females. Can show a small orange or bright red patch on the center of the belly. Found in a wide variety of habitats including savanna, woodland, gardens, farmland, mangroves, forest edge, and gallery forest. The main call is an agitated series of rising “k-k-kree” calls. The range overlaps slightly with the very similar Mountain Gray Woodpecker. Distinguished by the barring on the wing and undertail and the lack of a large, deep red belly patch.
St. Lucia Amazon
Amazona versicolor
A stout inhabitant of wet montane forests; sometimes ventures into orchards. This species often appears green with a bluish head, though a variable amount of red is present on the chest and belly. In overflight, a small red patch on each wing can be seen above and below. No other parrots occur within its range, and no parrot commonly kept in captivity resembles this species. Calls include a somewhat sharp “ka-chuck” and plaintive “ay-uh.”
Principe Golden-Weaver
Ploceus princeps
The only weaver on Príncipe, where it is endemic. Typically yellowish with an olive back: male has a golden-orange wash to the head, while female has a plainer face and a white belly. Juvenile is like the female, but duller. Found in pairs and small groups; abundant in almost all habitats on the island. Song is an accelerated fizzling concluding with a wheeze: “pssht-pssht-pshhtt-dzrrt-dzrrt-dzt-dzt-dzr-dzr-dzr-dzr-dzr.”
