This little Falcon was seen on bitt three or four occasions. The speci- 

 men in the collection was shot just after it had made an unsuccessful 

 assault on a flock of black-birds (Scolecopliagiis cyanocephalus) which were 

 feeding on the ground in a corral. Its success was no doubt thwarted by 

 the ojDening of the door of the house near by, for it flew away frightened, 

 but fortunately came in our direction, and alighted upon a fence-post within 

 easy gunshot range.
