Double-banded Sandgrouse
Pterocles bicinctus
A plump, small-headed, pigeon-like bird. At close range the male is identified by a combination of black-and-white bands just above bill and by a strong yellow eye-ring; the female is mottled with black, brown, and white. It prefers using patches of recently-burnt grassland near rocky areas in savanna. Largely inactive by day; large numbers synchronously gather at waterholes to drink, call, and socialize briefly at dusk before dispersing to forage throughout the night. Its distinctive calls are squeaky and bubbling: “oh NO, he’s gone and done it AGAIN!”.
识别特征
A moderately-sized, quail-like bird with a plump body, the double-banded sandgrouse has a small, almost pigeon-like head with a long pair of wings and tail. The general colour of the plumage is light brown, with darker mottling and rows of whitish specks; the male is distinguished by having a conspicuous black-and-white band on his forehead, with a chestnut-coloured throat that is delineated by another black-and-white band. Both sexes have an area of bare, yellow skin surrounding their eyeball, and the male has an orange beak. The female is smaller and a more dull-brown in colour. The juveniles resemble the female.

分布与栖息地
The double-banded sandgrouse is found in Angola, Botswana, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe. It has a preference for short trampled grass beside roads and tracks, gravel patches, tussocky grassland and recently burned areas of scrub with green shoots starting to develop. It is also seen in areas of scanty vegetation beneath scattered Terminalia sericea and Burkea africana trees and in scrubby mopane woodland. It is less common than Burchell's sandgrouse (Pterocles burchelli) and Namaqua sandgrouse (Pterocles namaqua), both of which have an overlapping distribution in southern Africa.

European Goldfinch
Carduelis carduelis
Beautiful little finch with a sharp pink bill, cherry-red face, and brilliant black-and-yellow flashes in the wings. Juvenile (seen in late summer and autumn) has a plain head but is told easily by bold wing pattern. Uses a wide array of wooded and open habitats, from forests and gardens to steppe grasslands and meadows; often feeds on seeding thistles. Forms flocks in autumn and winter, gathering at food sources. Can be inconspicuous, but often detected by pleasant bubbling and twittering calls and song.
Lompobattang Flycatcher
Ficedula bonthaina
A tiny brown flycatcher with an orange throat, a conspicuous orange mark between bill and eyes, a chestnut tail, and a white belly. Inhabits dense understory of montane forest within its small range in southwest Sulawesi. Differs from female Snowy-browed Flycatcher in its chestnut tail and brighter, clean-cut throat patch. Separated from female Rufous-throated Flycatcher by brown head and nape and larger orange patch between bill and eye. Song comprises several high-pitched whistles, “too-tee-too”, sometimes interspersed with or followed by a short rattle. Also gives dry, rattling “chep” calls.
Jerdon's Baza
Aviceda jerdoni
Medium-sized raptor with a prominent white-tipped black crest that is usually erect. Shows conspicuous pale reddish barring on a white belly. Smaller size and narrower wing bases in flight separate it from hawk-eagles, and longer wings and completely feathered legs at rest separate it from Crested Goshawk and other accipiters. Sedentary across its range, occurring in wet tropical and subtropical forests across South and Southeast Asia. Difficult to see if not soaring; often tucked away in forest canopy.
