208 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



Eggs : May 8 to June 1 1. 



This bird probably does much of the damage for which the nearly innocent 

 Butcos or " Hen Hawks " are blamed. I have a specimen in my collection that 

 was killed with a whip after having flown into a barn at Magnolia in pursuit of 

 chickens. 



144 [334] Accipiter atricapillus (Wils.). 

 American Goshawk. 



Rare and irregular late autumn visitor ; October and November. 



There are seven specimens from the County in the collection of the 

 Peabody Academy, all taken in October and November. 



Mr. C. H. Houghton, of Rowley, has a fine female specimen that was 

 caught by a farmer of that town in a steel trap in his chicken-yard. Mr. J. A. 

 Farley reports one for Lynnfield, on November 19th, 1892. 



145 [337] Buteo borealis (Gmel.). 



Red-tailed Hawk ; " Hen Hawk." 



Rare summer resident, more common transient visitor, rare in winter. 



Eggs : April 27. 



With the cutting of the timber this bird has sought other regions, and has 

 greatly diminished in numbers during late years. 



146 [339] Buteo lineatus (Gmel.). 

 Red-shouldered Hawk ; " Hen Hawk." 



Permanent resident, common in summer, uncommon in winter. 

 Eggs : April 3 to June 6. 



This is our most common Hawk, except in the open country near the sea 

 where the Marsh Hawk takes first rank.
