Little Sunangel
Heliangelus micraster
Unmistakable; the only hummingbird within its limited range that has an orange throat patch. Otherwise dark emerald-green overall with a rather short, straight bill. Males and females are similar, but females have a smaller throat patch and a dingier grayish belly. Occurs on the east slope of the Andes from southern Ecuador to northern Peru from around 2,400 to 3,100 m. Visits feeders, but also can be found in the middle levels of temperate forest and edges.
识别特征
The flame-throated sunangel is 10 to 11 cm (3.9 to 4.3 in) long and weighs 3.6 to 4.1 g (0.13 to 0.14 oz). Its straight bill is blackish. Both sexes have dark metallic green upperparts. Their lower breasts are dark metallic green, their bellies grayish, and their vent areas almost white. Their tails are dark steel blue. Adult males of the nominate subspecies have a glittering blue-green frontlet just above the bill, a dark purplish blue chin, and an iridescent yellow-orange gorget with a glittering emerald green border. Adult females lack the blue-green frontlet, their chin is blackish, and their throat is white with green to dusky gray speckles and sometimes a few iridescent reddish orange discs. Juveniles are like the adult female but the male does not have the blackish chin. Males of subspecies H. m. cutervensis have a reddish orange gorget.

Red-throated Parrotfinch
Erythrura psittacea
Tiny fluorescent green-and-red finch, found only on New Caledonia and the nearby Isle of Pines. Inhabits forest edge, as well as other open wooded habitats, such as scrubby plantation margins, grassy forest clearings, coastal scrub, and mangroves. Forages on the ground and in low vegetation, usually in pairs or small to medium-sized flocks. Gives a cute-sounding falling “seet”, often while foraging in a group.
Spot-flanked Barbet
Tricholaema lacrymosa
Chunky, medium-sized black-and-white barbet. There is a black triangle on the throat and large spots on the sides of the belly. Found in a variety of habitats including moist woodland and gallery forest. Generally in lusher habitats than other closely related barbets. The two main calls are a slow series of “kwaa” notes and a fast series of nasal “kye” notes. Easily separated from similar barbets by the spotted underparts and pale eye.
Black Wood-Pigeon
Columba janthina
The largest pigeon in the region, with dark purplish plumage except for metallic green around the neck. Generally uncommon endemic of islands off Japan, and to a lesser extent South Korea and Taiwan. Occurs in mature broadleaf forests, where it forages on the ground or in canopy. Also favors pines, especially in the Ryukyu Islands. Rustles about loudly when feeding. Deep call and slow moaning song may recall the everyday Rock Pigeon.
