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 40% of wildlife watchers report a Dimorphic Egret sighting in Dar es-Salaam on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 138 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.
January and August–September
In those months about 60% of wildlife watchers report a Dimorphic Egret in Dar es-Salaam on a given day, against about 10% in February and October, the lowest months. Those are among Dar es-Salaam's driest months, with about 45 mm of rain a month against 260 mm in April.
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.
3rd of 3
Of the 3 cities where we can rate Dimorphic Egret sightings, Dar es-Salaam ranks 3rd at about 40%. The best odds are in Zanzibar City (Tanzania, about 50%) and Antananarivo (Madagascar, about 50%).
Same genus: Egretta
The closest relatives of the Dimorphic Egret that you can see in Dar es-Salaam (genus Egretta, Small Egrets and Herons) are Little Egret (about 50%), Black Heron (about 20%) and intermediate egret (about 10%), 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 Dar es-Salaam (24 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.
