Ruddy-breasted Seedeater

Sporophila minuta

Very small, finchlike bird of grassy and weedy areas in tropical lowlands, especially in marshy areas. Often in flocks, mixing readily with slightly larger White-collared Seedeater. Breeding male (only in spring–summer) is striking: slaty bluish above and rusty below with a rusty rump. Nonbreeding male, female, and immature are much plainer: buffy brown overall, paler below, with distinct paler wing edgings (unlike plain-winged White-collared Seedeaters in west Mexico), and distinct orangey tones to the bill (bill dusky on White-collared).

分类信息

The ruddy-breasted seedeater was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Loxia minuta. The specific epithet is from Latin minutus meaning "little" or "small". The type locality is Suriname. The ruddy-breasted seedeater is now placed in the genus Sporophila that was introduced by the German ornithologist Jean Cabanis in 1844.<p>Three subspecies are recognised:

Atlantic Black-throated Trogon

Atlantic Black-throated Trogon

Trogon chrysochloros

Yellow-bellied trogon with pale blue eyering and yellowish bill. Male has shimmering green-blue upperparts and chest; female is brown. Underside of tail barred black and white with large white tips. Found in forested areas, usually sitting still at low to middle heights (often lower than other trogons in range). From other trogons in range by combination of head and chest color, tail pattern, and voice. Listen for song: a slow, evenly-spaced series of 4-8 slurred whistled notes.

Tepui Spinetail

Tepui Spinetail

Cranioleuca demissa

Small, creeping bird of highland forest canopy. Chestnut cap, wings, and tail contrast with olive-brown back and gray underparts. At close range, note somewhat decurved bill. Found only in humid highland forests of the tepui region (above 800 m), particularly in areas with heavy growth of mosses and epiphytes. Forages by hitching up large branches and tree trunks, and also creeps along limbs, inspecting bromeliads and bark crevices from which it gleans insect prey. Often encountered with mixed-species flocks. Voice is a long series of high tinkling notes, dropping in pitch and accelerating. No similar species occurs in tepui highlands.

Indian Silverbill

Indian Silverbill

Euodice malabarica

Small, long-tailed finch with a chunky body and short, stout bill. Gray-brown above and pale below with a whitish rump and black-pointed tail. Highly sociable throughout the year. Found in semidesert, scrub, and dry woodland but also proliferates in urban areas. Distribution is centered on the Indian subcontinent, but it is a popular cage bird and feral populations are widespread. Gives sharp “tsik” and “tseet” calls.
