56. RUFFED GROUSE (Partridge)— Bonasa umheltiis.

neighborhood, though formerly quite common. Thick sprout

 places like Marvel wood.

 corded from Pond Rock and Street's Woods in East Haven. 

 Most plentiful near North Haven. Arrives early in April. 



58. MARSH HAWK— 0>«^5 hudsonius. 



Spring and Fall transient, occasionally wintering : probably 

 a few nest here. Arrives some time in March, leaves in the 

 middle of April. Seen again late in August, quartering low 

 over marshes and meadows in search of mice. A decidedly 

 beneficial species. 



59. SHARP-SHINNED YiK^'Yi—Accipitervelox. 

 Permanent resident, rather common in winter, even in the 



city. Nests here, preferring hemlock groves. Migrates in large 

 unmbersin August and .September. One of our smallest hawks ; 

 like the following, very destructive to poultry and small birds. 



60. COOPER'S Yih^NYi—Accipitcrcooperi. 



Fairly common Winter resident : nests here. In the Spring 

 and Summer to be seen almost anywhere in the outskirts of the 

 city. Except that it is distinctly larger it closely resembles the 

 preceding in appearance as well as in habits. 



61. GOSHAWK— ylcc«>//^r atricapilhis 



Very rare Winter visitant, nesting far to the north. De- 

 structive to poultry. Seen in East Haven, in January, 1908. (?) 



62. RED-TAILED HAWK— />^«/^o borcalis. 



Winter resident, going north about April i. Not so com- 

 mon at any time as the next. One of our largest hawks. For-

63. RED-SHOULDERED ViKWYi—Buteo lineatus, 



A common permanent resident ; nesting in tall trees almost 

 anywhere outside of the city : West River, Street's Woods, E.

 popularly given to this and the preceding species are misleading, 

 as neither attacks poultry to any extent.
