Hume's Lark
Calandrella acutirostris
Small, pale brown lark. Sandy-colored above and whitish below, with distinct white eyebrows and a slender bill. Greater Short-toed Lark is extremely similar, and distinguished only with difficulty; in Hume’s, look out for a plainer and relatively unstreaked crown, more contrastingly white eyebrows, and a more slender bill. The same combination of characteristics, along with a plain unmarked chest, can also be used to eliminate Asian Short-toed Lark. Clean underparts, lack of a strong crest, and size serve to distinguish Hume’s from other larks. Breeds in high-altitude steppe and plateau regions, in dry areas with sparse vegetation; winters in similar habitat at lower elevations. Song flight is composed of jumbled whistled, warbled, and harsher buzzing notes with long pauses between phrases; includes more whistling than similar-sounding Greater Short-toed Lark, and averages shorter-phrased in full song flight and slower overall. Call is a rolling, buzzy “cheeer,” drier and more rattling than that of Greater Short-toed.
识别特征
Hume's short-toed lark is similar in size and appearance to the greater short-toed lark but is generally a duller-looking bird with slightly darker plumage and a slightly smaller beak. As with the greater short-toed lark, the colour varies across the broad range and is not a good distinguishing feature. Hume's short-toed lark grows to a length of from 13 to 14 cm (5.1 to 5.5 in) and the sexes are similar. The crown is brown with slight diffuse streaking, the cheeks are rufous-brown and the supercilium white. The upper parts are greyish-brown or sandy brown with darker streaking, and the upper tail coverts are washed with rufous-brown. The wings are greyish-brown with black barring and pale tips to the feathers. The underparts are mostly whitish, but there is a dark neck patch and a buffish-grey breast band. The breast is unstreaked. The voice helps distinguish this species; vocalisations include a shrill "trree" and a more rolling "drreep".
分类信息
The name commemorates the British naturalist Allan Octavian Hume who described the species. The alternate name short-toed lark may also be used for three other species in the genus Calandrella. The alternate name lesser short-toed lark should not be confused with the species of the same name, Alaudala rufescens. Other alternate names for Hume's short-toed lark include Hume's lark and Karakoram short-toed lark.<p>Two subspecies are recognized:

California Quail
Callipepla californica
Small and rotund with obvious teardrop-shaped plumes protruding from forehead. Looks gray and brown at a distance, with white streaks on the sides and a scaly belly. Males have black face and longer, more curled crest than females. Usually seen in flocks running on the ground in open, scrubby habitats. Listen for frequent, three-noted call, audible at long distances. Separated from similar Gambel’s Quail by range; also note California has scaly belly with rusty (not black) patch and duller brown crown and sides. Native to western North America including Baja California; well-established introduced populations in Chile, Argentina, New Zealand, and Hawaii.

Keel-billed Toucan
Ramphastos sulfuratus
Large unmistakable toucan with a huge, rainbow-colored bill. Often seen in pairs, but not usually in groups like aracaris. Flies with a few flaps followed by a swooping glide, sometimes high over the forest canopy, and looks like a ‘flying banana.’ Heard more often than seen: ‘song’ is a far-carrying, frog-like croak, repeated steadily. Despite its large size and bright colors, can be difficult to see in leafy canopy, where it moves deliberately in search of food.

Green-headed Oriole
Oriolus chlorocephalus
Old World oriole with mostly yellow plumage, a dull-green hood, and a red bill. Found in forest, forest edge, lush woodland, and adjacent secondary habitats, at low and middle elevations. Song is a series of slurred, liquid whistles, and calls include a raspy, up-slurred whine. Similar to African Black-headed Oriole, but with a good view, easily separated by the green rather than black hood. Often found in the same areas as Eurasian Golden and African Golden Orioles, but distinguished by being hooded rather than yellow-headed.
