Scrub Euphonia
Euphonia affinis
Tiny finch of tropical lowlands and foothills, especially in drier areas. Occurs from eastern Mexico to Costa Rica, where it is found in open woodland, forest edge, and clearings with trees. Usually in pairs, sometimes small groups that associate readily with other euphonias, especially when feeding at mistletoe. Male has black head and throat with yellow forehead patch; female rather drab, but lacks vested appearance of female Yellow-throated Euphonia, which is slightly larger.
识别特征
Both sexes have a thin, fine bill, smaller than that of other euphonias. Legs and eyes are dark. The male is bright yellow below and black above, with a small yellow spot on the forecrown. The crissum is white. Females have a grey head, dusky olive upperparts, buff-grey underparts, and white belly and crissum.
分类信息
Euphonia affinis is divided into several subspecies. The species E. godmani of the Pacific coast of central Mexico is now considered to be a full species, West Mexican euphonia (Euphonia godmani).

分布与栖息地
The scrub euphonia ranges on both coasts of Mexico, south from the states Sonora and Nuevo Leon, as well as much of the country east of the Isthmus of Tehuantepec, including the Yucatan Peninsula. It is found throughout Belize, Guatemala, Honduras and Nicaragua and along the Atlantic and Central and Northern Pacific coastal lowlands in Costa Rica. It can be found in areas of secondary growth, stands of trees, agricultural areas and gardens and other human-disturbed areas.

Eastern Clapper Lark
Corypha fasciolata
A medium-sized, stocky lark with a small bill and barred and scalloped feathers on the head and upperparts, giving it a scaly appearance. The plumage varies geographically, with South African birds being brighter and rustier, and northern birds being duller and grayer. Pairs forage for insects in grassland, often in rocky areas. During the September to February breeding season, the male perches on small rock or low bush, before rising up 3-5 meters in the air with a steady wing-clapping display, then giving a single whistled note “phoooee” and parachuting down to the ground on raised wings. The similar Cape Clapper Lark is smaller than Eastern Clapper Lark, with less rufous coloration on the body and wings, and an accelerating wing-clapping display.
Bronze Ground Dove
Pampusana beccarii
A rotund, short-legged ground-dwelling dove that usually runs rather than flies when startled. Both sexes have a brown body with bluish-gray chest and head. Males have an iridescent pink shoulder patch. Most obvious identification feature in the field is the glowing white eye-ring of the male, especially in more eastern populations such as those in the Solomon Islands. On mainland New Guinea, the species is a resident of upper-elevation montane forest. No other similar species occur in its altitudinal range. Gives a typical dove-like “woo-oop” call which is quiet and easily missed.
Great Skua
Stercorarius skua
Powerful dark brown seabird, resembles a dark, heavily built immature gull. Note eye-catching white flashes in the primaries when in flight. Adults have distinct pale mottling on the upperparts, which serves to separate them from adults of the very similar South Polar Skua. Juveniles are more uniformly colored, with warm-colored and largely unmarked underparts; note bulkier build and more powerful flight than Pomarine Jaeger. Breeds locally on moorland of islands and coasts in northern Europe, where aggressive near nests. Otherwise lives at sea, but may be seen from shore during windy conditions during migration periods. Feeds by pirating gulls and other seabirds, also by scavenging at fishing boats.
