This little Hawk is well known, and no visitor to the country will 

 long aw-ait a sight of their busy forms. They begin to leave the north- 

 ern part of the State in September, and some winters all leave. Se- 

 vere winters they often seek protection; in one instance in January 

 one was found in a stable, sharing a stall with a horse. Nowhere, 

 perhaps, are they so numerous in winter. In more open winters, their 

 numbers in the southern part of the State begin to increase in Feb- 

 ruary. Migrations then begin and continue through March. In the 

 Whitewater Valley I have always seen them mating in April. I have 

 found their nest as early as April 11, but fresh eggs are found farther 

 northward well into May. 



A favorite nesting site is a Woodpecker's hole in a dead limb, at 

 the top of a tall sycamore tree. The usual nesting site, in timber 

 countries, is a hole, natural or otherwise, in the top of a tree; some- 

 times, however, they are made quite low. Other places, they occa- 

 sionally nest in holes in cliffs or banks, or in the nest of some large 

 bird, like a crow, and in buildings. In trees, the eggs are Inirl upon 

 fragments of chips in the hole.
