From Butorides virescens Jiypernotius this form is distinguished by 

 its smaller size, lighter, more rufescent neck and sides of head, and 

 rather paler posterior lower parts. It is larger than Butorides vires- 

 cens hahamensis, with darker, less fulvescent (more purplish) neck 

 and sides of head, and darker posterior under parts; the ju venal 

 plumage is also darker, less grayish both above and below than the 

 corresponding age of Butorides v. hahamensis. The juvenal plumage, 

 to judge by the material examined, is similar to that of Butorides 

 virescens virescens, but is lighter, less heavily streaked below, aver- 

 aging also less rufescent; and is somewhat paler, more grayish above. 



This is a very good race, readily distinguishable from Butorides 

 virescens virescens by size and usually by color, although some speci- 

 mens seem to be practically the same in this regard. Individual 

 variation is considerable, involving chiefly the degree of rufescence 

 and paleness of the neck and the lightness of the posterior under 

 parts. The female is, at least in Cuba, somewhat larger than the 

 male, but in Porto Pico the reverse seems to be the case.
