The yellow-throated sparrow or chestnut-shouldered petronia (Gymnoris xanthocollis) is a species of sparrow found in southern Asia. It is a species mostly of the dry savannah. They forage on the ground for grain and for berries in bushes. They are often seen perched atop bare branches on trees while calling.
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.
This species has sometimes been lumped along with the yellow-spotted petronia (Petronia pyrgita) of Africa. Currently, two subspecies are recognized... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Yellow-throated Sparrow is recorded against all the birds logged in Kalyan-Dombivli (115 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
