The grey plumage and stature of Grey Herons make them unmistakable. It is a very familiar species being widely distributed and a year-round resident in Ireland. Single birds are often flushed when posed motionlessly at the edge of water bodies, coiled ready to strike out at unsuspecting prey with its formidable spear-like bill.
It feeds along the edge of a wide range of wetland habitats from coastal waters and estuaries to loughs, streams and marshy ground. They are usually encountered as solitary birds and sometimes as a pairs, although if observing breeding colonies - heronries - numbers can be in the 50s.
