This is the common Sparrow-Hawk of North America, where it is usually called the 
Sharp-shinned Hawk, and takes the place of Accipiter nisus of Europe. In America 
it breeds over most, if not all, of the States, as well as in the British Provinces as far 
as the Arctic circle °. 
In Mexico and Central America it is probably to a large extent a winter visitant, 
though some may remain to breed, especially in the northern parts. Grayson says that 
he met with it at all seasons in Western Mexico, but he never was able to find a 
nest, though convinced that it bred in the district 1’. In other parts of Mexico it is 
a very common bird, and ranges in altitude from the sea-level to the Valley of Mexico.
