For interesting articles on the nesting and breeding habits 

 of Hawks in this state, consult those of C. L. Rawson, who has 

 made a special study of Hawks in Norwich, as noted in the 

 bibliography. 



One instance of the development of both ovaries has been 

 noticed by L. B. B. 



Astur atricapillus atricapillus (Wilson). Goshawk. 



A rather rare and irregular winter resident, occasionally 

 appearing in considerable numbers. 



Earliest record. Oct. 5, 1886, New Haven (L. C. S.). 



Latest record. April 12, 1907, Guilford (S. E. Watrous, in 

 coll. of L. C. S.). 



Large flights recorded in January, 1897, especially in the 

 northern and eastern parts of the state (J. H. S.) ; in early No- 

 vember, 1906, and on through to March, 1907, near New Haven 

 (L. B. B.) ; and in the fall of 1907, in different parts of the state 

 (J. H. S.). 



There are about thirty-five records of this species being either 

 seen or captured in this state. 



Breeding record. H. K. J.^ records that " Mr. Williams 

 found a nest in Winchester, about fifteen years ago [about 

 1893]. It was in a chestnut tree, sixty feet up, and contained 

 two eggs. He shot the female for identification, and has the 

 eggs and complete data." 



Buteo borealis borealis (Gmelin). Red-tailed Hawk. 



A common resident of the wooded hills of the interior of the 

 state ; much rarer on the coast except in the fall migrations. 



Most abundant (Portland) from April 15 to May 25, and 

 from Oct. I to Nov. 25, although recorded there during the en- 

 tire year. The majority pass through the state as migrants, but 

 this species winters regularly in small numbers throughout the 

 state, and is more common on the coast at that season than in 

 summer. 



Nest. Very large nest of sticks and twigs, usually in a 

 deciduous tree, from 45 to 75 feet from the ground. It favors
