Although not noticed by Dr. Hayden during the Warren explora- 

 tions, this handsome and spirited little Hawk was observ^ed by natnral- 

 ists of the Raynolds' Expedition, and ranges over the whole of the Mis- 

 souri region, as elsewhere on our continent. It is one of the best known, 

 and, in most sections, one of the more abundant of our birds of this 

 family. It preys chiefly upon small birds aud quadrupeds, captured iu 

 the dashing manner of all the species of this gronj), and, like its small 

 allies, feeds to some extent upon insects. It nests in trees, or on rocks, 

 I)referably the former, laying four or five eggs. They are difficult of con- 

 cise description, because so variable. The white ground-color has often 

 a livid or even purplish tint, and is ujarked, often so thickly as to be 

 obscured, with large, irregular splashes of various shades of brown, 

 interminably changeable iu number, size, and pattern, sometimes inclin- 

 ing to form masses or a wreath, sometimes more evenly distributed. 

 The Q^,Q is of nearly equal size at both ends, aud measures about 1.45 

 bv 1.15.
