Scarlet-backed Woodpecker
Veniliornis callonotus
Small, colorful woodpecker of western Ecuador and northwestern Peru. Most common in dry, deciduous forest and scrub, but also inhabits degraded rainforest. Both sexes have red back and white underparts that may show very faint barring. Male’s cap is red and female’s is black. Typical song is a long, rattling trill.
识别特征
The scarlet-backed woodpecker is about 13 cm (5.1 in) long and weighs 23 to 33 g (0.81 to 1.2 oz). Males and females have the same plumage except on their heads. Adults of both sexes of the nominate subspecies have a generally grayish brown and white face. Males are red from forehead to nape with black tips on many feathers. The female is entirely black there. Both sexes' upperparts are brownish-scarlet. Their flight feathers are dark brown with redder secondaries and tertials. Their tail is blackish-brown whose central pair of feathers is blacker and the outer pair whitish yellow with black bars. Their underparts are white with a very light buff wash and sometimes darker but faint vermiculation. The iris is deep brown (occasionally deep red), the beak yellowish with darker base and tip, and the legs are greenish gray. Juveniles have heavy olive or grayish mottling on their upperparts and are buffier white on their underparts. Their head pattern is more diffuse than the adults'. Adults of subspecies V. c. major have a darker face and darker vermiculation on the underparts than the nominate.
分类信息
The International Ornithological Committee and BirdLife International's Handbook of the Birds of the World place the scarlet-backed woodpecker in genus Veniliornis. However, starting in 2018, the American Ornithological Society and the Clements taxonomy moved all species of genus Veniliornis into genus Dryobates.<p>The above taxonomic systems recognize two subspecies, the nominate V. c. callonotus and V. c. major (Berlepsch & Taczanowski, 1884):

分布与栖息地
The nominate subspecies of scarlet-backed woodpecker is found from Colombia's Nariño Department south through western Ecuador to Guayas Province. V. c. major is found from El Oro and Loja provinces in Ecuador south into Peru as far as La Libertad Department. The species inhabits arid scrublands, dry deciduous woodland, semi-humid forest, dense riparian forest, and sometimes partially cleared areas. In elevation it mostly occurs from near sea level to 1,000 m (3,300 ft), less frequently to 1,500 m (4,900 ft) in Peru, and locally as high as 1,800 m (5,900 ft) in Ecuador.

Barred Long-tailed Cuckoo
Cercococcyx montanus
Rufous-brown, heavily barred cuckoo with an unusually long tail. There can be a wash of rufous on the throat and/or breast. Found in forest and thick woodland, including some miombo. Shy and retiring, and most easily found by voice. There are two main vocalizations; one is a long series of slurred “tseeeuw” calls which become more empatic. This sometimes leads into the second call type, which is a four-noted “toot tweet tow tweet.” Similar to other long-tailed cuckoos, but the adult is easily separated by the rufous barring on the upperparts.
Black-streaked Scimitar-Babbler
Erythrogenys gravivox
A large, dark scimitar-babbler. Brown upperparts and white underparts separated by an orangish stripe running along either side of the bird from the face down to the vent. Lightly backswept mustache and a jagged band across the breast are made of the eponymous black streaks. Found in forest, edge, weedy fields, and gardens. Like many other scimitar-babblers, has a frequently-used and advanced repertoire of hoots, cackles, and rattles.
Hispaniolan Oriole
Icterus dominicensis
A sleek forest bird that sometimes ventures into gardens and parks in search of flowers and fruit; prefers areas with palms. The adult is distinctive—clothed in black except for patches of yellow on lower belly, shoulders, and rump. No similar species occur within its range. Immatures are muddled yellow, orange, and olive, developing adult plumage over the course of a year. This plumage resembles that of female and young Baltimore Orioles, a scarce migrant and winter visitor to Hispaniola. Similarly attired Baltimore Orioles can be distinguished by their orange underparts and white wingbars. The song is a rapid jumble of squeaky and metallic notes. Calls include a buzzy “jrrrt” and a metallic “zhwee.”
