killed between November 1 and May 1. During the season of 1929-30, 

 9 sharp-shinned, 120 Cooper's hawks, and 76 goshawks were sent in. 

 together with 296 harmless or beneficial hawks. And the following 

 season the score was 180 harmful hawks, against 255 useful species. 

 This seems a big price to pay for the few goshawks destroyed. Most 

 men cannot, or will not, distinguish the good hawks from the bad. 



DISTRIBUTION 



Range. — North America, casual in the British Isles, 



Breeding range. — The two races of the American goshawk {A. a. 

 airicapillus and A. a. striatulus) breed north to Alaska (Bethel, 

 Yukon Delta, Nulato, Bettles, Big Creek, and Fort Yukon) ; western 

 Mackenzie (rarely Fort Good Hope, Fort Anderson, and the Grandin 

 River) ; Saskatchewan (Beaver Eiver, Wingard, and Pelican Nar- 

 rows) ; Manitoba (Riding Mountain and Portage la Prairie) ; north- 

 ern Ontario (Moose Factory) ; Quebec (Great Whale River and 

 Fort Chimo) ; and Newfoundland Labrador (Hopedale). East to 

 Newfoundland Labrador (Hopedale) ; Newfoundland (Nicholsville 

 and Fox Island River) ; Nova Scotia (Pictou, Wolfville, and Hali- 

 fax) ; Maine (Calais and Norway) ; New Hampshire (Alstead) ; 

 Massachusetts (Petersham) ; Connecticut (Winchester Center) ; 

 eastern Pennsylvania (Lopez) ; and rarely northern Maryland 

 (once, at Jennings in 1901). South to rarely Maryland (Jennings) ; 

 Michigan (Mackinac Island and Isle Royale) ; probably Colorado 

 (Breckenridge and Lone Cone) ; possibly New Mexico (mountains 

 west of Taos) ; probably northern Arizona (San Francisco Moun- 

 tain) ; and central California (Lake Tenayo). West to California 

 (Lake Tenayo, probably Pyramid Peak, Donner, Eagle Lake, and 

 Mount Shasta) ; Oregon (Glendale) ; Washington (Bumping Lake 

 and probably Lake Cushman) ; British Columbia (Chilliwack, Cari- 

 boo District, Dock-da-on Creek, and Hot Springs) ; Yukon (Lake 

 Marsh) ; and Alaska (Chitina Glacier, Chulitna River, and Bethel). 



The western form {striatulus) appears to breed only in the Pacific 

 coast district, from about Cook Inlet, Alaska, south to the Sierra 

 Nevada of California, wintering east to Colorado. The eastern form 

 {atricapiUus) is more wide ranging, particularly in winter, when 

 specimens have been collected west to California. 



Winter range. — The normal winter range includes most of the 

 breeding range, but in some seasons (depending largely upon the 

 status of the food supply in the north) goshawks will work south 

 to Florida (Lake lamonia and St. Petersburg) ; Texas (Center 

 Point) ; central Arizona (Fort Verde) ; and southern California 

 (Lower Otay Reservoir, near the Lower California line). 



Migration. — ^A study of the data available indicates that the mi- 

 gration of the goshawk can not be satisfactorily illustrated by dates
