So far as I am able to judge after a very careful comparison of specimens from Central 

 America with, those from the Greater Antilles, there is not even an average difference 

 in either size or coloration between the two series. The individual variation is very 

 considerable in both lots, but it seems to me impossible to satisfactorily distinguish 

 the continental from the island birds, as a whole.
