The dimorphic egret (Egretta dimorpha) is a species of heron in the family Ardeidae. It is found in Comoros, Kenya, Madagascar, Mayotte, Seychelles, and Tanzania. The dimorphic egret is sometimes considered as a subspecies of the western reef egret (Egretta gularis) or as a subspecies of the little egret (Egretta garzetta).
The dimorphic egret can sometimes be found on rooftops, finding insects in the gutters of houses. Taylor, D. (2010). "The Egretta garzetta complex in East Africa. A case for one, two or three species". Scopus. 30: 59–62. Wikipedia →

Likely
About 50% of wildlife watchers report a Dimorphic Egret sighting in Antananarivo on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 69 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 70% of wildlife watchers report a Dimorphic Egret in Antananarivo on a given day, against under 5% in April, the lowest month. That is one of Antananarivo's driest months, with about 60 mm of rain against 480 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dimorphic 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.
Among the best
Of the 3 cities where we can rate Dimorphic Egret sightings, Antananarivo ranks 2nd at about 50%, level with the leaders once rounded. The best odds are in Zanzibar City (Tanzania, about 50%).
Same genus: Egretta
The closest relatives of the Dimorphic Egret that you can see in Antananarivo (genus Egretta, Small Egrets and Herons) are Little Egret (about 80%) and Black Heron (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dimorphic Egret is recorded against all the birds logged in Antananarivo (51 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.
