Some authorities classify the intermediate egret species complex in its own monotypic genus, Mesophoyx, while others place it with the smaller egrets in Egretta. There were three recognised subspecies, and these are sometimes raised into species:
A.i. intermedia Wagler, 1827 "intermediate egret" - Asia from the Russian Far East to Japan to India and the Greater Sundas A.(i.) intermedia differs from A.(i.) brachyrhyncha and A. (i.) plumifera by having a black bill when in breeding plumage, while A.(i.) plumifera has a yellow-and-pink bill and A. (i.) brachyrhyncha has much yellower lores and face.

With luck
About 10% of wildlife watchers report an intermediate egret sighting in Kolkata on a given day, based on 841 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
December and January
In those months about 20% of wildlife watchers report an intermediate egret in Kolkata on a given day, against under 5% in April–June and August–September, the lowest months. Those are among Kolkata's driest months, with about 10 mm of rain a month against 330 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most intermediate egret sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
69th of 123
Of the 123 cities where we can rate intermediate egret sightings, Kolkata ranks 69th at about 10%. The best odds are in Thiruvananthapuram (India, about 40%), Ponnani (India, about 40%) and Kochi (India, about 30%).
GBIF citizen-science records
It is estimated from how often the intermediate egret is recorded against all the birds logged in Kolkata (841 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.
