88 BIRDS OF SOUTH DAKOTA 



357. PIGEON HAWK (Falco columbarius columbarius.) 



Probably seen only in migration in South Dakota. From 

 eleven to twelve inches in length. Male above bluish slate; 

 throat usually nearly white; belly light but streaked with 

 brown; tail with four dark bands, the wide end one tipped with 

 white. Female and young, dark brown above; below buffy and 

 more heavily streaked with brown ; tail with four or five bands. 



357b. RICHARDSON'S PIGEON HAWK (Falco columbarius richardsoni.) 



This Hawk is not common in the State but probably 

 nests occasionally. In size and plumage it clearly resembles No. 

 257 but is more of a grayish drab in color, and usually has six 

 bands on the tail. 



360. SPARROW HAWK (Falco sparver'ms sparverius.)

 of our Hawks, measuring not over ten or eleven inches in length. 

 The crown of both sexes is bluish slate, usually with a chestnut

 back and one wide black bar on tail; wing coverts bluish slate; 

 under parts creamy white with black spots. Female: chestnut 

 brown above, with many blackish bars on back and tail; below 

 whitish, streaked with brown. Its food is chiefly mice, grass- 

 hoppers, beetles, and occasionally small birds.

Rather rare in South Dakota. Crown white streaked with 

 black; throat and breast white or streaked with brown; black

This Owl has been rarely taken except in the southern 

 part of South Dakota. Length about eighteen inches; above, 

 buff mixed with gray; below, white and tawny usually with
