Resident. In northern part of the State, rare in winter. Most nu- 

 merous during migrations, and in summer. Some severe winters they 

 are rare. Prof. Cooke says, in the ^\•inter of 1883-4. none were re- 

 ported north of 38 degrees (liinl Mig. ^[iss. A^alley. p. 114). It has 

 been noted in the following rounties. through the -winter: Liike 

 (l\reyer). Fulton (BarnelH, Carroll (Evermann). Monroe (Blatehley), 

 Knox (Balmer). and Franklin. Breeds throughout the State. In fall 

 they migrate — in September and October: in spring, in March. They 

 are mated early in April and looking for nesting sites or repairing an 

 old nest. The site is the fork or notch of some tree, generally from 

 '20 to 50 feet from the ground. SonuHimes Ihey build a new nest, at 

 other times they occupy that of the prmeding year or even an old nest 

 of some other hawk, or of a st|uirrel. The m>sts are sometimes very 

 bulky, others well constructed and shapely. They begin laying in 

 .\pril. and full sets of eggs have been taken from April t^o to ^lay 

 10. One brood is reared a year, thouirh if the first laving is destroyed, 

 a second, or. in case of loss of second, a third set has been known to be 

 laid, sometimes in the same, sometimes in another nest. The eggs are 

 deposited at intervals of one to two days, and incubation does not 

 begin till the set is nearly completed. The female does most of the 

 incubating and the male supplies her with food.
