The western reef heron (Egretta gularis), also called the western reef egret, is a medium-sized heron found in Africa and parts of Asia, with vagrancy occurring in Europe and the Americas. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage which can only be confused with the rather uncommon dark morph of the little egret (Egretta garzetta); a white form which can look very similar to the little egret, although the reef heron's bill tends to be paler and larger; and a black form with a white throat, E. g. gularis, found in West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the little egret, and based on this, some authors treat schistacea and gularis as subspecies of Egretta garzetta. Works that consider the western reef heron as a valid species include the nominate gularis and schistacea as subspecies.
This bird has two plumage colour forms. There is an all-white morph and a dark grey morph; morphs can also occur with intermediate shades of grey which may be related to age or particoloured in grey and white. The white morph is similar... Wikipedia →

With luck
About 10% of wildlife watchers report a Western Reef Egret sighting in Kollam on a given day, based on 191 verified sightings from GBIF citizen-science data. It is the 66th most-seen of the 173 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Western Reef Egret in Kollam on a given day, against under 5% in March to August, the lowest months. That is one of Kollam's driest months, with about 15 mm of rain against 330 mm in October.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Western Reef 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.
18th of 29
Of the 29 cities where we can rate Western Reef Egret sightings, Kollam ranks 18th at about 10%. The best odds are in Manama (Bahrain, about 70%), Kuwait City (Kuwait, about 50%) and Karachi (Pakistan, about 40%).
Same genus: Egretta
The closest relatives of the Western Reef Egret that you can see in Kollam (genus Egretta, Small Egrets and Herons) are Little Egret (about 50%) and intermediate egret (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Reef Egret is recorded against all the birds logged in Kollam (191 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.
