The lesser whistling duck (Dendrocygna javanica), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.
This chestnut brown duck is confusable only with the fulvous whistling duck (D. bicolor) but has chestnut upper-tail coverts unlike the creamy white in the latter. The ring around the eye is orange to yellow. When flying straight, their head is held below the level of the body as in other Dendrocygna species. The crown appears dark and the sexes are alike in plumage. They fly slowly but with rapid wing-flapping and usually produce a repetitive wheezy seasick call as they circle overhead. They are very nocturnal and often rest during the day. The... Wikipedia →

No species of the same family or order lives in Savar, so these are its closest relatives here: other birds.
Likely
About 60% of wildlife watchers report a Lesser Whistling-Duck sighting in Savar on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 99 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January and February
In those months about 70% of wildlife watchers report a Lesser Whistling-Duck in Savar on a given day, against about 40% in July, the lowest month. Those are among Savar's driest months, with about 15 mm of rain a month against 380 mm in July. October has too few records to rate.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Lesser Whistling-Duck 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.
Yes
Of the 67 cities where we can rate Lesser Whistling-Duck sightings, Savar has the highest daily chance: about 60%. Next come Ponnani (India, about 30%) and Indore (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Lesser Whistling-Duck is recorded against all the birds logged in Savar (68 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.
