The Indian pond heron or paddybird (Ardeola grayii) is a small heron. It is of Old World origins, breeding in southern Iran and east to the Indian subcontinent, Burma, and Sri Lanka. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations.
They are distinctive when they take off, with bright white wings flashing in contrast to the cryptic streaked olive and brown colours of the body. Their camouflage is so excellent that they can be approached closely before they take to flight, a behaviour which has resulted in folk names and beliefs that the birds are short-sighted or blind.
Indian pond herons are stocky with short necks, short thick bills and buff-brown backs. In summer, adults have long neck feathers. Their appearance is transformed from dull colours when they take to flight and the white of the wings makes them very prominent. They are very similar to the squacco herons, Ardeola ralloides, but darker backed. To the east of their range, they are replaced by the Chinese pond herons, Ardeola bacchus.

Rare
Under 5% of wildlife watchers report an Indian Pond Heron sighting in Namdapha National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 239th most-seen of the 298 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Indian Pond Heron in Namdapha National Park on a given day, so our monthly data shows no clear season. June to September have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Indian Pond Heron sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
25th of 26
Of the 26 parks where we can rate Indian Pond Heron sightings, Namdapha National Park ranks 25th at under 5%. The best odds are in Keoladeo National Park (India, about 80%), Kaziranga National Park (India, about 80%) and Yala National Park (Sri Lanka, about 70%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Indian Pond Heron is recorded against all the birds logged in Namdapha National Park (18 verified sightings from 2019 to 2026), 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.
