Scarlet Robin
Petroica boodang
Large Australian robin. Males black above, with a black head and chin, and a large white spot above the bill. Breast and belly bright scarlet. Black wing shows extensive white panels. Females brownish above, pale below, with reddish breast patch, dark upperwing with pale panels, and large white spot above bill. In Tasmania, similar Dusky Robin lacks pale panels in the wing. Inhabits open woodlands as well as farmland and grasslands in southeastern and southwestern Australia and Tasmania. Perches low, snatching prey from the ground.
识别特征
Like the rest of the Australasian robins, the scarlet robins are stocky passerines with large heads. They range in size from 12 to 13.5 cm in length and weigh between 12 and 14 g. The plumage is sexually dimorphic. The males have black heads, backs and tails, black and white wings, a scarlet red breast, and white belly, forehead and rump. The female matches the male in pattern, but is duller, with brown plumage instead of black, a much more washed-out red on the breast, and a buff belly. Juvenile birds resemble the female without the reddish wash on the breast.

行为
The scarlet robin feeds on arthropods, such as insects and spiders. It adjusts its foraging behaviour seasonally, feeding mostly on the ground during the winter, but during the summer and spring prey is more commonly snatched from bark and foliage.<p>The scarlet robin is a territorial and monogamous species, and defends its nesting territories both from others of the same species and from pairs of the related flame robin. Territories are established and breeding commences before the migratory flame robin arrives in its range (where the two co-occur). Both the male and the female participate in selecting the nesting site, but only the female constructs the nest, a task which takes four to ten days. The clutch size is between one and four eggs, with three being the average. The eggs are grey, green or pale blue, and marked with brown to olive-brown splotches and spots, usually concentrated around the large end. Only the females incubate the eggs, and the males feed the females on the nest. The chicks hatch after 14 to 18 days. At first, they are brooded by the female and fed by the male; when brooding ends, they are fed by both parents. Nesting success is generally low, between 8 and 40%. Scarlet robin nests are raided by snakes, and they are victims of brood parasitism by various species of cuckoo.

Micronesian Rufous Fantail
Rhipidura versicolor
Small, active songbird with long, pale-tipped tail and warm brownish-orange on the forehead, rump, and tail base. Grayish brown above and pale below overall, with a white throat and black-speckled breast. Frequently cocks and fans tail. Endemic to the Mariana Islands (Saipan, Tinian, Agiguan, and Rota) and Yap, in the Carolina Islands. Extinct on Guam. Inhabits a wide range of habitats, from remnant native forests to towns. High-pitched, tinkling song often has a descending quality. Formerly grouped with other closely related species under “Rufous Fantail.”
African Green-Pigeon
Treron calvus
A plump pigeon with green wings and back, dull burgundy shoulders, and a whitish bill with a red base. It prefers forest and thicker woodland, where nomadic groups congregate in fruiting trees, especially figs. They clamber around clumsily like parrots but can remain well hidden. When disturbed, they explode from a tree and fly quickly and directly. Often detected by their amusing song, which includes whinnies, clicks, whistles, cackles, and growls. African Green-Pigeon lacks the bright yellow belly of the similar Bruce’s Green-Pigeon.
Greenish Yellow-Finch
Sicalis olivascens
Common in foothills of the Andes, from barren rocky canyons to villages, agricultural terraces, and scrubby hillsides, mainly at lower elevations than Bright-rumped Yellow-Finch, which favors puna habitats. Male is well-named—drab greenish yellow overall. Female is notably drab and nondescript. In all plumages note lack of any streaking or contrastingly bright yellow areas. Compare with longer-winged Greater Yellow-Finch (some overlap of range in winter).
