SHARP-SHINNED HAWK HI 



On the south shore of Lake Ontario, east of Rochester, N. Y., 

 sharpshins are frequently abundant in spring, the height of the 

 flight occurring during the latter part of April and the first week 

 of May. The birds pass along the south shore of the lake and around 

 the eastern end en route to breeding grounds in Canada (Eatt)n, 

 1910). 



N. A. Wood reports (1911) that for several days during the spring 

 season this species is common on the Charity Islands, in Saginaw 

 Bay, Mich. 



At Whitefish Point in the eastern end of Lake Superior, hundreds 

 of these hawks have been observed during the period from May 13 

 to June 3. 



Fall migration. — It sometimes seems that the autumnal movement 

 of the sharpshin is timed to coincide with the southward flight of 

 sparrows and warblers, which at this season furnish a large part of 

 its food. 



At Point Pelee, Ontario, the flight begins late in August and 

 continues through September or occasionally to the latter part of 

 October. During the height of the migration it is not unusual for 

 25 or more of these hawks to be in sight at one time. 



Fishers Island, N. Y., is one of the best known "hawk observa- 

 tories." At that point several flights usually occur, the first gen- 

 erally about September 13, the second and main flight about Septem- 

 ber 20, while the third or last flight is usually about the end of 

 September or the first of October (Ferguson, 1922). These times 

 agree with autumnal observations at the eastern end of Long Island, 

 and in New Jersey. 



Casual records. — In Bermuda, a sharp-shinned hawk was taken 

 near Pennistons Pond on February 23, 1853, and another was shot 

 near Stocks Point sometime prior to 1884. Sometimes this species 

 is fairly common in the Bahama Islands, as Bryant (1861) reported 

 that at Nassau it appeared to be the most common hawk and that a 

 number were seen in different places. Todd and Worthington (1911) 

 reported seeing sharp-shinned hawks at Mathew Town, Great Inagua, 

 on February 22, 1909, and also at Acklin Island.
