*154. Nyctale acadica Bon. SAW-WHET OWL; ACADIAN OWL. 

 Rather common and probably resident. (See Deane, Bull. Nutt. Orn. 

 Club, II, 84.) 



155. Nyctale tengmalmi Bon. (JV. richardsoni auct.) TENG- 

 MALM'S OWL. Rare winter 3 visitor. Recent records of its occurrence 

 are: Lynn, 1803 (Allen, Am. Nat., Ill, Feb., 1870, 646); Cambridge, 

 Dec., 18C5 (Maynard, Nat. Guide, 1870, 133). 



156. Nyctea scandiaca Newt. SNOWY OWL. A more or less 

 regular winter visitant. Very abundant during the winter of 1876-77. 

 (See Deane, Bull. Nutt. Orn. Club, II, 9, 1877.) 



157. Surnia ulula Bon. HAWK OWL. Very rare winter visitor 

 in most parts of the state; probably of rather frequent occurrence in 

 the more elevated parts of Berkshire County. (For the record of its 

 occurrence see Am. Nat., Ill, Dec., 1869, 569.) 



158. Speotyto cunicularia var. hypogsea Cones. BURROWING 

 OWL. Accidental. Newburyport, May 4, 1875 (Deane, "Rod and 

 Gun," VI, 97, May 15, 1875). 



*159. Circus cyaneus var. hudsonius Schl. MARSH HAWK. 

 Common summer resident. 



160. Nauclerus furcatus Vig. SWALLOW-TAILED HAWK. Acci- 

 dental. One record of its occurrence (to me a satisfactory one), but 

 none of its capture (Whately, about 1868, Allen, Am. Nat., Ill, Feb., 

 1870, 645). Mr. Merriam gives it as "a rare straggler from the 

 South," and cites two instances of its occurrence in that state (Rev. 

 Birds Conn., 1877, 76).

 common summer resident.

 mer resident; of occasional occurrence in winter.

 ter visitant. Has been seen in summer, and perhaps occasionally 

 breeds. 



164. Falco gyrfalco Linn. GYRFALCON. Of rare or accidental 

 occurrence in winter. 



164. Falco gyrfalco var. labradora Ridy. BLACK GYRFALCON.

 more common in winter than in summer and along the coast than in 

 the interior.

 occurring chiefly in spring, fall, and winter.
