Yellow-throated sparrow
The yellow-throated sparrow or chestnut-shouldered petronia (''Petronia xanthocollis'') is a species of sparrow found in Asia.
== Description ==
It has a finer bill than typical sparrows of the genus ''Passer'' and unlike them has no streaks on the plumage. The white double wing bar on the shoulder is diagnostic on the otherwise dull grey-brown sparrow. Males have a chestnut shoulder patch which can sometimes be hard to see. They also have a pale yellow spot on the throat in fresh plumage. Females are duller and lack the chestnut shoulder patch.〔 The yellow spot is much reduced or lacking in females.
This species is tree-loving although sometimes seen on wires and on the ground, where it has a hopping gait. The usual call is a ''chirrup'' but the song is distinctive and repetitive ''chilp chalp cholp''. It has a bounding flight and dips deeply before rising up.
