The white-breasted waterhen (Amaurornis phoenicurus) is a waterbird of the rail and crake family, Rallidae, that is widely distributed across South and Southeast Asia. They are dark slaty birds with a clean white face, breast and belly. They are somewhat bolder than most other rails and are often seen stepping slowly with their tail cocked upright in open marshes or even drains near busy roads. They are largely crepuscular in activity and during the breeding season, just after the first rains, make loud and repetitive croaking calls.
Adult white-breasted waterhens have mainly dark grey upperparts and flanks, and a white face, neck and breast. The lower belly and undertail are cinnamon or white coloured. The body is flattened laterally to allow easier passage through the reeds or undergrowth. They have long toes, a short tail and a yellow bill and legs. Sexes are similar but females measure slightly smaller. Immature birds are much duller versions of the adults. The downy chicks are black, as with all rails.
Several subspecies are named for the populations that are widely distributed. The nominate subspecies is described from Sri Lanka but is often widened to include... Wikipedia →

Possible
About 20% of wildlife watchers report a White-breasted Waterhen sighting in Kalyan-Dombivli on a given day, based on 250 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 179 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June

GBIF citizen-science records
It is estimated from how often the White-breasted Waterhen is recorded against all the birds logged in Kalyan-Dombivli (250 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.
