BTO Bird ID – Little Egret and Great White Egret

12 March 2013

25 years ago the sighting of any White Heron in the UK would have been greeted with excitement. While Little Egret is now relatively common, it can sometimes be confused at distance with a much rarer visitor – Great White Egret. This video also helps separate GW Egret from ‘white’ or leucistic Grey Herons.

The Dutch SOVON ornithologists report on counting wintering great egrets in October 2017.

The birds were counted at the roosts where they sleep. They were over 7,100, a record number. The biggest roost was in Kollumerwaard nature reserve: 352 great egrets.
