Of the present species and its many allies, A. frazari, A. saturata, A. bahamensis, &c., 
it is difficult to write definitely, as we have not been able to examine a sufficiently large 
series of the insular forms, which have been separated as distinct by the American 
ornithologists. Dr. Bowdler Sharpe, in the ‘ Catalogue of Birds,’ recorded his opinion 
that the differential characters assigned to some of these species or races are due to the 
intensity of colouring during the breeding-season, and on the whole we are inclined 
to agree with him. 
The Green Heron is found on both the Atlantic and Pacific sides of North America, 
but is apparently absent in the central regions of the United States. It becomes less 
common in the northern portions of its range, but breeds in Canada in limited numbers, 
a few pairs remaining all the winter in the Southern States. Plentiful in all the 
States of Central America, where it mostly appears as a winter visitant or on migration, 
this species, according to Grayson, is resident in Western Mexico at all seasons, and 
also at San José in Costa Rica, as recorded by Mr. Cherrie. We found large numbers
