and darker green. Some females seem never to get the green 
on the speculum, and those that do assume it, get only a dull 
dark green—never, I think, the light bright green of the males. 
Some females too have all the covertsa uniform grey like the 
males ; but in the case of the former it is at most a slatey grey, 
more or less dull, and never the purer light lavender grey of the 
latter. In the young female both bill and feet should be 
lighter coloured, and more leaden. 
In this species, as in others, the under surface, normally white, 
is often strongly tinged with ferruginous.
