Bimaculated Lark
Melanocorypha bimaculata
Chunky ground-dwelling songbird with large-headed, short-tailed profile, found in arid open areas such as deserts and steppe. Readily confused with other large larks, but look for the bulky, dark-tipped bill, rounded ear patch, and a black band below the throat with a break in the middle. Calandra Lark is similar but shows a bright white edge to the trailing edge of the wing and blackish underwings in flight. Song is a long series of grating warbles, whistles, and twitters. Calls are buzzy and rather deep.
识别特征
This is a large, robust lark, 16–18 cm in length. It is an undistinguished looking species on the ground, mainly streaked grey above and white below, and with two small black patches on the breast sides, which give this species its name. It has a white supercilium.<p>In flight it shows short broad wings, which are grey-brown below, and a short tail with a white tip, but not white edges. The wing and tail patterns are distinctions from its more westerly relative.<p>The song is like a harder version of that of calandra lark.
分类信息
The bimaculated lark was originally placed in the genus Alauda. The current genus name, Melanocorypha is from Ancient Greek melas, "black", and koruphos a term used by ancient writers for a now unknown bird, but here confused with korudos, "lark". "Bimaculate" and the specific bimaculata are from Neo-Latin bimaculatus, "two-spotted". The alternate name calandra lark should not be confused with the species of the same name. The alternate name Eastern calandra lark is also used for a subspecies of the calandra lark.

Marsh Seedeater
Sporophila palustris
A small finchlike bird. Males have a gray hood and back with a rusty belly that contrasts with white plumage extending from the cheeks to the breast. The “zelichi” morph is deep brown above and below with a black cap and a white breast and head. Females are olive-brown above and buff below. Both sexes have a white wing spot. Inhabits marshy areas with tall mature grasses; can be found in flocks with others seedeaters during migration.
Kittlitz's Murrelet
Brachyramphus brevirostris
Small, oblong-shaped seabird. Breeding plumage mottled brown; darkness varies, but often shows golden tint. Nonbreeding plumage dark gray above and white below, with a white face and large white wing patch. Nests in crevices in rocky scree slopes, particularly around glaciers; forages in coastal glacial outflows. Similar to Marbled and Long-billed Murrelets, but with shorter bill and white outer tail feathers; breeding birds average paler with speckled back, while nonbreeders show white on face extending above the eye.
Red-legged Seriema
Cariama cristata
Unmistakable large terrestrial raptorial bird. Sandy-colored overall with very long red legs, a long tail, and tufty crest in front of the eyes. Note the strong red bill and large pale eyes with blue eyerings. Strides elegantly through open and lightly wooded savannas but also perches on the top of trees. Usually sings at dawn, an evocative and incredibly loud “kuap-kuap-kuap-kuap” often delivered as a duet for extended periods.
