The Little Egret (Egretta garzetta) is a small member of the heron family Ardeidae which also includes Bitterns and Herons. It is found in the temperate parts of Eurasia and Africa as well as in Australia and New Zealand. Over the last 60 years or so this species has greatly expanded its range including recolonising its former breeding areas in Northern Europe. It first bred in the Caribbean in the mid 1990’s and is increasingly being recorded along the North American eastern seaboard.
