turn about overhead, displaying as it sails the fine barred pattern of its wing- 
linings and its long square-ended tail; but oftener the bird is aware of your 
presence in advance and keeps warily out of range. It is not infrequently

It is idle to try to speak a good word for this gory little Hawk; rodents 
and insects are eaten only occasionally, while birds of every size up to pigeons 
and quails are its regular diet. According to Dr. Fisher, of 107 stomachs 
examined containing food, six held poultry or game birds, “og other birds; 
6 mice; 5 insects.”

THIS is the real culprit. This is the “Chicken Hawk” par excellence. 
Punish him who will! Of larger size than the preceding, this bird with the
