Waterbird Wednesday week 8 - Little Egret
The Little Egret (Egretta garzetta) is now a relatively common species across the UK, despite first successfully breeding here as recently as 1996. Numbers of this distinctive heron continue to rise in the country, with a breeding population of around 700 pairs that mainly nest in the south of the country. There is also a good wintering population of around 4'500 individuals. They feed on fish like other herons.
Identifictation
Little Egrets are a distinctive species, with a long dark bill, long legs and white plumage.
