webs, and narrowly tipped with white. 
“Cheeks with a patch of black, most narrow and clearly defined in the 
adult bird, and separated from the color of the back of the head by a white 
space; back of the neck mixed with yellowish feathers, forming an irregu-

This bird is a little larger than the European Peregrine Falcon; and the 
young, the above quoted author says, differ. 
The cut is taken from Audubon’s plate, and represents the male in im- 
mature plumage.

HYPoTrIoRCcHIS COLUMBARIUS—/inn—THE PIGEON HAWK. 
Wilson’s Am. Orn., IT., pl. 15, fig. 8; Audubon’s B. of Am., Oct. ed., 
I, pl. 21. This handsome little hawk is of pretty common occurence in 
this State. Dr. Kirtland says that it is a permanent resident. A pair 
have built their nests for several years past near his house at Rockport, 
and he has observed them during the whole season. They visit his barns 
and out-houses in pursuit of mice and other small prey. He shot two 
young specimens, but the old are too shy to be approached within shot. 
They are now in very fine dark plumage; the young being much lighter 
colored. Its name of pigeon-hawk is probably derived from its size, which 
is that of a pigeon, and not from any habit of making war on that bird. 
Its food consists of small quadrupeds, such as mice, and, in all probability, 
frogs and small snakes. Small birds may also be destroyed by it, but it is 
too small to harm any of the denizens of the farm yard. 
The head and body of this little hawk are broad and strong. Tarsi and 
toes slender, but stronger than those of the Sharp-shinned Hawk—Accipi- 
ter fuscus. Bill short; wings with the second and third quills longest; tail
