The female differs in having the green of the head and back replaced by purplish chestnut; 
the brownish yellow tints more hoary ; the feathers of the throat with a narrow central dusky 
streak. 
An allied species in South America, (A. erythromelas ,) according to Bonaparte, has the hack 
purplish chestnut, instead of dark green. The European A. minuta differs in being larger; the 
upper wing coverts milk white, not brownish yellow ; the under wing coverts white, instead of 
olivaceous yellow.
