White-faced heron

Description

The adult white-faced heron is medium-sized for the family and mostly pale blue-grey.The forehead,crown,chin and upper throat are white.The crown pattern is variable,with the white occasionally spreading down the neck;the variability makes identification of individuals possible.The iris may be grey,green,dull yellow or cinnamon.The regions between the eye and bill on the side of the head (lores) are black.The beak is black and often pale grey at the base.During the breeding season pinkish-brown or bronze nuptial plumes appear on the foreneck and breast,with blue-grey plumes appearing on the back.The adult typically weighs 550 g (1.21 lb) and ranges from 60 to 70 cm (24–28 in) in height.Immature birds are paler grey with only the throat white,and often have a reddish colour on the underparts.Chicks are typically covered with grey down.
