Accipiter velox. Of 20 female Sharp-shinned Hawks, chiefly young, 
which I have skinned since August, 1902, both ovaries were developed 
in 17. As a rule the left was the larger, but occasionally both were small 
and distinguishable from testes only by a magnifying glass. I suspect 
some unusually large ‘males’ in collections are in reality such females. 
I have also found both ovaries developed, though rarely, in Accipiter cooperi, 
Buteo platypterus, Asia wilsonianus, and Cryptoglaux acadica.
