During the fall of 1907 Mr. James Ward of Britt, Iowa, sent to the Coe College Museum a hawk of the Genus Buteo, that, because of its color, was difficult to identify. It was so similar to a specimen seen by the writer in the collection of mounted birds at the Smithsonian Museum in Washington, that at the suggestion of Mr. W. E. C. Todd of the Carnegie Museum at Pittsburg, it was sent to Mr. Robert Ridgway of the National Museum at Washington, where both these gentlemen affirmed that it is a Broad Winged Hawk in melanistic plumage.
