Study of egret bills
It was crowded at Technopol Thursday morning. Hundreds of white egrets, as well as other bird species, flocking in the swamps and the lakes. It was a wonderful sight. But with so many seemingly similar tall, white birds on the same spot it would be nice with a quick comparative guide for identification. It comes below – at least for three of the species.
In this photo are three different species of white egrets presented next to each other.
- On the left; Great White Egret (Egretta alba) – identification hint; tallest of the white egrets, yellow bill (black when breeding – darkens from tip to base). Important: Gape extends behind the eye.
- On the right; Intermediate Egret (Egrette intermedia) – identification hint; smaller than Great White. Yellow bill (red/orange when breeding). Gape line does not extend behind the eye.
- In the middle; Little Egret (Egretta garzetta) – identification hint; Black bill.

The rocky coast of Dakar, forming the Cap Vert Important Bird Area, is an outstanding site for seabirds (photo: P. Robinson). Technopole and its numerous waders, herons, gulls, terns and other waterbirds (including Greater Flamingos when conditions are right) is one of the best sites for birds in the greater Dakar region (photos: B.
