A. herodias appears to be the American representative of the Common Heron 

 {A. cinereo) of Europe, which it resembles in size, plumage, and habits. This species 

 is found throughout the greater part of North America, and breeds in suitable places 

 from the Atlantic to the Pacific, as well as in Cuba and some of the West-Indian 

 Islands. It appears to be a resident in Northern Mexico, but in other parts of Central 

 America the bird is chiefly known as a winter visitor.
