Desert Lark
Ammomanes deserti
Medium-sized lark of arid zones. Pale sandy overall with a strong yellowish-based bill and faint breast streaking. Differs from the similar Bar-tailed Lark by larger bill and broader diffuse dark tail band. Call is a soft “chup.” Song is a repeated phrase of flutey notes. Walks and runs on the ground, searching for small arthropods and plant material. Found in various desert habitats including sandy plains and rocky slopes.
识别特征
The desert lark is a medium-sized, big-headed and long-billed lark, growing to a length of 16 to 17 cm (6.3 to 6.7 in). The sexes are alike, but there is considerable geographical variation. It has a rather dull plumage which can vary from quite pale to rather dark. Plumage may vary between subspecies but individuals within populations can be variable too. It is similar in appearance to the bar-tailed lark but is slightly larger, has a less-domed head, a larger broader beak, stouter legs and a longer tail. The upper parts of the many subspecies vary in colour; most are pale greyish brown, but some races are very washed out and others are quite a deep colour. Some have some rufous colour on wings and tail, similar to the bar-tailed lark, but the underparts are a pale pinkish grey and have much more streaking than that species, and the desert lark lacks the clearly defined terminal black band on the tail of that species, although it may have a rather diffuse dark patch. The colour variation seems to mainly match the habitat, so sandy-coloured birds are commoner in sandy areas, greyer birds in rocky areas and the darkest birds in desert dominated by basalt.<p>The song is a mournful choo-wee-chacha wooee, uttered from the ground or a boulder, or during undulating flight. It is more mellow and less squeaky than that of the bar-tailed lark. When flushed it utters a short churree or chee-lu.

分布与栖息地
The desert lark is found from Mauritania, Western Sahara and southern Morocco in the west east through northern Africa south to Chad and Somalia through south west Asia to western India.<p>It is resident (non-migratory) apart from local movements in arid stony areas, and avoids flat sand and will always be found in broken terrain with a vertical element to it

行为
The desert lark is not very sociable and does not form large flocks, being mainly encountered in small groups or as single birds. They are territorial when breeding, nesting on the ground under the shelter of a tussock or stone in a shallow scrape lined with plant material and having a rim of pebbles, which may surround the nest or be on the more exposed side of the nest. The clutch is 1-5 eggs and these are laid at different times in various parts of its range, e.g. January–February in the south and March–April in the north. The desert lark eats seeds and insects, the latter especially in the breeding season.

Thick-billed Euphonia
Euphonia laniirostris
Small finchlike bird, compact and short-tailed. Generally yellow below and dark blue-black above with stout bill. To identify male euphonias, focus on crown and throat: on Thick-billed, crown is entirely yellow and throat is yellow. Females are extremely difficult to separate from other euphonias, especially Yellow-crowned, but often seen in pairs or small groups with more distinctive males. Frequents open forested habitats, edges, and gardens. Can form mixed feeding flocks with other species such as warblers and tanagers.
Pacific Robin
Petroica pusilla
A small, attractive robin with a bright crimson chest and belly. Varies across range, but male is mostly dark above and on head except for bright white forehead and pale wingbar. Base of undertail white. Female mostly brown above but red below. Generally unique and unmistakable within range. Inhabits forested areas at a range of elevations. Voice varies across range but is generally a mix of high-pitched tinkling, sweet high-pitched tweeting, and whistling.
Pied Wheatear
Oenanthe pleschanka
Jaunty little terrestrial songbird of plains, agricultural fields, and semi-desert, where often perches prominently on utility wires and boulders. Tuxedoed breeding male is black with snow-white crown, belly, and rump. Female is sandy brown above and white below. Nonbreeding adult and immature have sandy underparts and pale fringes to the wing feathers, producing a worn, scaly look. Note black-and-white tail pattern in all plumages. Circles and plunges in an impressive display flight, in which a rambling series of whistles, trills, and buzzes are given. Calls include twangy “bi-zee!”, dry “chak” notes, and short, falling “dew.”
