*154. Nyctale acadica Bon. Saw-whet Owl; Acadian Owl. 

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

 Club, IT, 8-L) 



155. ISTyctale tengmalmi Bon. (iV. richardsoni auct.) Teno- 

 malm's Owl. Rare winter visitor. Recent records of its occurrence 

 are: Lynn, 1SG3 (Allen, Am. Nat., Ill, Feb., 1S70, G4G); 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 Bun. 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, 1SG9, 5G9.) 



158. Speotyto cunicularia var. hypogsea Coues. Burrowing 

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

*159. Circus cyaneus var. hudsonms 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 18G8, Allen, Am. Nat., Ill, Feb., 

 1870, G45). Mr. Merriam gives it as "a rare straggler from the 

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

 Birds Conn., 1S77, 7G).

 mer resident; of occasional occurrence in winter.

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

 breeds.
