" dry hillsides where the woods are rather open and a wide range 

 of view can be had." (C. L. R.) 1 



Eggs. I to 3 ; early in April. 



Nesting dates. Earliest record. March 24, 1903, two eggs 

 (Beers). Latest record. April 30, 1888, two eggs (Eames) ; 

 May 23, 1873 (W. W. C). 2 



This species will occupy the same nest year after year unless 

 disturbed, when it will build another nest in the vicinity (W. W. 

 C. 2 and C. L. R.). 3 



Mr. Rawson also notes the facility with which they are mated 

 when one of the pair is killed, the survivors often pairing within 

 a week or two, leading to the supposition that the old ones prob- 

 ably pair with the young of previous years. 3 



Buteo lineatus lineatus (Gmelin). Red-shouldered Hawk. 



A common resident of the lowlands of the larger river valleys 

 and the marshy woodlands of the coast; the majority passing 

 farther south in October and returning in March, but many win- 

 tering regularly throughout the state. 



In breeding these hawks return regularly to the same woods, 

 and often use the same nest as the previous year, unless that was 

 robbed. In that case they usually take the one in which they had 

 succeeded in raising their second set, or the nest occupied in an 

 earlier year. If the first set is taken, a second set is laid in from 

 three weeks to a month. 



The following nesting records are a summary of 112 occupied 

 nests of this species examined by L. B. B., as well as about 60 

 examined by C. L. R.* 



Nest. Location: all in deciduous trees; chestnuts (72, L. B. 

 B., 39, C. L. R.), oaks (22, L. B. B., 10, C. L. R.), maples (9, 

 L. B. B., i, C. L. R.), beeches (i each), yellow birch, ash, and 

 hickory. Height: average, 35-50 feet from the ground, with the 

 extremes of 20 (C. L. R.) and 75 (L. B. B.). Situation in tree: 

 usually in the forking of the trunk at the top of the tree, fre- 

 quently lower down against the trunk at a point where two or
