The black-rumped flameback (Dinopium benghalense), also known as the lesser golden-backed woodpecker or lesser goldenback, is a woodpecker found widely distributed in the Indian subcontinent. It is one of the few woodpeckers that are seen in urban areas. It has a characteristic rattling-whinnying call and an undulating flight. It is the only golden-backed woodpecker with a black throat and a black rump.
The black-rumped flameback was described and illustrated by two pre-Linnaean English naturalists from a dried specimen that had been brought to London. In 1738 Eleazar Albin included the bird as the "Bengall Woodpecker" in his A Natural History of Birds and in 1751 George Edwards included the "Spotted Indian Woodpecker" in his A Natural History of Uncommon Birds. The black-rumped flameback was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Picus benghalensis. He cited the earlier descriptions by Albin and Edwards. This woodpecker is now placed in the genus Dinopium that was introduced by the French polymath Constantine Samuel Rafinesque in 1814.

Possible
About 20% of wildlife watchers report a Black-rumped Flameback sighting in Chattogram on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 43rd most-seen of the 76 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Black-rumped Flameback in Chattogram on a given day, against about 10% in February, June and October–December, the lowest months. That is one of Chattogram's driest months, with about 10 mm of rain against 780 mm in July. April and July–August have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-rumped Flameback sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
31st of 57
Of the 57 cities where we can rate Black-rumped Flameback sightings, Chattogram ranks 31st at about 20%. The best odds are in Savar (Bangladesh, about 70%), Tamluk (India, about 60%) and Thiruvananthapuram (India, about 60%).
Same family: Picidae
The closest relatives of the Black-rumped Flameback that you can see in Chattogram (family Picidae, Woodpeckers) are Streak-throated Woodpecker (about 20%), Eurasian Wryneck (about 10%) and Fulvous-breasted Woodpecker (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-rumped Flameback is recorded against all the birds logged in Chattogram (14 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.
