Lark Sparrow

Chondestes grammacus

Large and boldly patterned sparrow. Look for unique black, white, and rufous face pattern, brighter on adults and duller on immatures. Favors open areas with scattered trees when breeding; often forms flocks in brushy areas in winter. Usually feeds on the ground and flies up into trees when disturbed. In flight, notice long tail with broad white corners.

The lark sparrow is distinctive. Adults have a typically sparrow-like dark-streaked brown back, and white underparts except for a dark central spot. The cheeks and crown sides are chestnut, with white eyebrow and crown stripes. The dark tail's corners are also white. Young lark sparrows are duller, and the underparts are streaked.<p>Measurements:

分布与栖息地

It breeds in southern Canada, much of the United States, and northern Mexico. It is much less common in the east, where its range is contracting. The populations in Mexico and adjacent states of the United States are resident, but other birds are migratory, wintering in the southern United States, Mexico and south to Guatemala.<p>It is a very rare vagrant to western Europe, with two accepted records in Great Britain in 1981 and 1991.[citation needed]

Olive-capped Warbler

Olive-capped Warbler

Setophaga pityophila

A lively small inhabitant of pine woodlands, typically found fairly high in trees. Similar to Bahama Warbler and Yellow-throated Warbler at first glance, but Olive-capped Warbler has a bright yellow-olive forehead and lacks the bold white eyebrow of those species. Also distinctive is the Olive-capped's dense, dark streaking that is restricted to the sides of the lowermost chest. Its song consists of several sweet notes on one pitch followed by several at a lower pitch; sometimes ending with a single note on original pitch. Call notes include one that is high and sharp and another that is sweet and slightly squeaky.

White-browed Tit-Warbler

White-browed Tit-Warbler

Leptopoecile sophiae

A tiny purplish-blue bird with a chestnut cap, a soft pink belly, and a pale brow that is not always prominent, and more often grayish than white. Lacks the pale head of Crested Tit-Warbler. Breeds in high-altitude forests and scrub, but descends into foothills in the winter. Usually seen singly, in small flocks, or as a part of mixed flocks. Gives high crisp-sounding notes, usually in pairs.

King Penguin

King Penguin

Aptenodytes patagonicus

Large, spectacular, and basically unmistakable penguin that is rarely seen away from well-known colony sites. The long and stout bill distinguishes King from the even larger but shorter-billed Emperor Penguin, which is a true Antarctic species, rarely seen far from ice. Also note the golden neck patches (can fade to whitish on immatures) and pink bill base (bill starts out black on immature). Breeding season requires more than a year, so birds can be seen year-round at colonies.
