I06 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB 



on December 17, 1913. On June 22, 1913, 1 saw a Bald Eagle at Ipswich. Mr. 

 G. M. Bubier has seen two and sometimes three of these birds near Groveland in 

 the winters of 1915, 1916, and 1917. On January 28, 1916, he saw two in full 

 plumage at Groveland. 



In the last week of August, 1916, 1 several times saw an immature Bald Eagle 

 at Ipswich Beach where it fed on dead fish. This bird showed by its tracks on 

 the beach that it walked with short steps dragging its toes. From the tip of the 

 hind toe to the tip of the middle toe the distance was six and a half inches. 



The flight of this splendid bird is strong and vigorous. I have seen them 

 soar in a strong breeze to a great height, at first in large and then in small circles, 

 without a perceptible movement of the wings. The secondary feathers of the 

 great wings appeared almost as long as the primaries which are spread so that 

 each feather is distinct by itself and bent up at the ends. Arrived at a great 

 height they sometimes volplane down with amazing speed. 



In the adults the snowy white head and tail flash out alternately in the sun- 

 light as they soar, and they present a magnificent sight. 



The cry of this bird is a piercing whistle. I have also heard them emit a 

 grunting noise. 



*i56 [353] Falco islandus Brtinn. 



White Gyrfalcon. 

 Very rare winter visitor. 



I am glad to be able to add this bird to the list on the authority of Mr. Jewell 

 D. Sornborger. He writes me under date of March 7, 1912, that " on January 

 20, 1912, in the 'far division' of the Rowley woods I saw a white hawk flying 

 along Mud Creek towards its mouth . . . this bird seemed so white that I think it 

 must have been islandus." 



1 once had the great privilege of seeing this bird at Henley Harbor, Labrador. 

 It was flying about the great cliff, alighted on a shelf and fluttered and hopped a 

 few paces. It was one of a pair that had been observed there for several years 

 by Dr. Grenf ell. 



[354^] Falco rusticolus gyrfalco (Linn.). Gyrfalcon. — An erroneous record. 



157 [354b] Falco rusticolus obsoletus Gmel. 



Black Gyrfalcon. 

 Very rare winter visitor. 



In addition to the three records given before I have the following note to 

 offer. On January 6, 1918, after a week of zero and below-zero weather, a large
