Charles Co., February 16, 1904; latest December 4, 1902. Ear- 

 liest for Clark Co. (Currier), February 21, 1892; latest in spring, 

 April 25, 1897; in fall, December 5, 1899. Pairs are occasionally 

 seen in summer (June 18, 1901, Clark Co., Currier, and June 17, 

 1906, in Saline Co.), but whether they breed has not been ascer- 

 tained. 



150. Aythya collaris (Donov.). Ring-necked Duck. 



Anas collaris. Fulix collaris. Fuligula collaris. Anas fuligula. Anas 

 (Fuligula) rufitorques. Ring-neck. Ring-bill. Blackjack. 



Geog. Dist. — North America, rare on North Atlantic Coast. 

 Breeding from southern Minnesota and North Dakota northward 

 to Lake Athabasca; sparingly west of the Rocky Mountains. 

 In winter chiefly along the Gulf Coast to Central America and 

 Cuba; north to the Carolinas and the Ohio River. 



The Blackjack is a very common transient visitant in Missouri. 

 The first arrive from the south about a week after the first Mal- 

 lards and Sprigs have come. In short winters the species may be 

 absent a few weeks only. In the vicinity of St. Louis the first 

 have been noted February 18, 1898; in some years they were not 

 seen before the middle of March, but usually varying numbers 

 are frequenting the marshes of northeastern Missouri from March 

 10 to April 10, sometimes to the end of the month (April 28, 1893, 

 Clark Co., Currier). Their presence in fall is also governed 

 largely by the weather conditions. In 1903 they were plentiful 

 in St. Charles Co. from October 3 till December 4; in other 

 years they came as late as October 20 and were gone a month 

 later.

 icana. Anas clangula (in Wilson). Clangula glaucium. Clangula vul- 

 garis. Bucephala clangula. Whistler. Great Head. Garrot. Whistle- 

 wing. 



Geog. Dist. — North America; breeding from Newfoundland, 

 New England, northern Michigan, North Dakota, Montana and 

 British Columbia northward in wooded regions to the Mackenzie 

 River and Alaska. It winters abundantly on the Atlantic coast 

 from the British Provinces to South Carolina, along the Pacific 

 coast, and less commonly on the Gulf coast. 



In Missouri the Whistle-wing is a frequent transient or winter
