Descriptive notes.
12-13 cm, 20-22 g, wingspan 23-27 cm. Rather small, quite slim sparrow, with noticeably long bill. Male most colorful west Palearctic member of rather nondescript genus, yellow patch on throat, chestnut patch on forewing, white tips to median coverts, and dark bill. Female and juvenile lack yellow and chestnut.
Little seasonal variation.
Habitat. In west Palearctic, breeds in subtropical lower middle latitudes, mainly in lowlands, but up to 750-1200 m in Himalayan foothills. Favours open dry forest or forest scrub, oases, groves, gardens, and cultivated areas with scattered trees, shrubs, or hedgerows.
Food and Feeding.
In breeding season, diet insects and planet material, at other times principally plant material, mainly seeds. In breeding season, forages more often in trees than sparrows, in remainder of year on ground, commonly in large flocks with sparrows, finches, and buntings, under trees or in fields of millet and or sorghum, taking milky seeds on cereal heads, or on ground in stubble.

Nest site, hole or crevice in tree, building, or other man-made structure, may use old hole of woodpecker or barbet, or old, possibly usurped, nest of Red-romped Swallow. Most often recorded in acacia, taqmarisk, and date palm sometimes simply behind bark.

3-4 eggs, sub-elliptical, smooth and very slightly glossy. Very variable in color, even within clutch, ranging from greenish to brownish-white, heavily speckled, blotched, and streaked with all shades of brown, often obscuring ground-color.
