No specimens of this species were taken by either of the Expeditions, j '- 

 and if, indeed, the bird ranges throughout the Missouri region, it must'' 

 be uncommon. The name occurs in Prof. Snow's list, but without 

 remark. The latitudinal dispersion of the species appears to be quite 

 restricted ; I have never heard of it from the fur countries, nor indeed 

 anywhere beyond the United States, excepting in (Janada and NoVa 

 Scotia. It reaches, however, across the continent ; examples from the 

 limited Pacific slopes are, as might be expected, more heavily colored 

 than ordinary, but It hardly seems necessary to recognize them by name. 

 Southern-born birds are considerably smaller than the average, as noted 

 by Prof. Verrill, in comparing Maine and Florida examples. In the 

 Atlantic States it is one of the most abundant of the birds of prey. 

 The nidiflcation is similar to that of B. horealis ; the eggs, as usual, 

 have a wide range of variation in color ; they measure from 2.00 to 2.25 

 in length by about 1.75 in breadth ; they number from two to four. 

 The general habits of the species are much the same as those of allied 

 large Hawks.
