and said to breed on Graylock (Brewster, Auk, I, 1884, 10). Mr. 

 E. H. Forbush informs me of a specimen taken in Paxton, Wor- 

 cester County, October 22, 1884. 



*170. Haliseetus leucocephalus. BALD EAGLE. Rare resi- 

 dent. 



[171.] FaltO rusticolllS. GRAY GYRFALCON. Of rare or ac- 

 cidental occurrence in winter. There are various records. 



[1710.] Falco rusticolus obsoletus. BLACK GR\Y,FALCON. 

 Casual or accidental. Breed's Island, Boston Harbor, Oct. 1876 

 (Cory, Bull. Nutt. Orn. Club, II, 1877, 27); Essex County (Pur- 

 die, Bull. Nutt. Orn. Club, IV, 1879, 189); Stowe, 1881 (Brewster, 

 ibid., VIII, 1883, 184). There are also Vermont, Maine, Rhode 

 Island and Long Island records. (For New England records of 

 Gryfalcons see Purdie, in Stearns and Coues's " New England 

 Bird Life," II, 1883, no, in; Jencks, Auk, I, 1884, 94.) 



*172. Falco peregrinus anatum. DUCK HAWK. Rare 

 resident; more common in winter than in summer, and along the 

 coast than in the interior. Mount Tom and Sugar Loaf Moun- 

 tain are well known as among its breeding places, and it doubtless 

 breeds elsewhere in the western part of the State, as it does at 

 various localities in Connecticut and in the Helderberg Mountains 

 near Albany, N. Y. (Lintner, Auk, I, 1884, 391). 



173. Falco COlumbarius. PIGEON HAWK. Rather rare, 

 occurring chiefly in spring, fall, and winter. 



' : '174. Falco sparverius. AMERICAN SPARROW HAWK. More 

 or less common resident; most numerous, however, in spring and 

 fall. 



; * 175. Pandion haliaetus carolinensis. AMERICAN OSPREY. 

 Occasional summer visitant. Formerly bred in the State, but now 

 nests here very rarely. Mr. F. H. C[arpenter] refers to a colony 

 of u about forty nests " on Palmer River, near Rehoboth (Orn. 

 and Ool., IX, 1884, 100). 



[176.] Strix pratincola. AMERICAN BARN OWL. Very rare 

 or accidental. Only two specimens as yet known to have been 

 taken in the State one at Springfield, May, 1868 (Allen, Proc. 

 Essex Inst., V/, 1868, 312); the other at Lynn, in 1865 (Allen, 

 Am. Nat., Ill, 1870, 646). [July,
