Aix sponsa (Linn.) Wood-duck. 



Breeding Range. — The wood-duck is more closely con- 

 fined to the United States than any other North Ameri- 

 can duck. South of this country it is not a rare resident 

 in Cuba and is accidental in Jamaica and the Bermudas. 

 It occurs in California south to Los Angeles and Ventura 

 counties, in the latter of which it breeds. There is a 

 single record for Mexico, at Mazatlan. It breeds in 

 eastern Texas, south rarely to San Antonio ; thence to 

 the Pacific slope and north throughout the whole Rocky 

 Mountain region it is rare or accidental. It is recorded 

 as breeding in southwestern Colorado (Fort Lewis), 

 northern Idaho (Fort Sherman), northern Montana 

 (Flathead Lake), and as a rare migrant in various locali- 

 ties south to New Mexico and Arizona. 



The northern extension of its range is found in Nova 

 Scotia and New Brunswick, for the species is not yet 

 recorded from Newfoundland, and there seems to be no 

 reliable record for Labrador. It ranges at least as far 

 north as Montreal, Ottawa, Moose Factory, Trout Lake 

 and Cumberland House. It appears to be absent from 

 the Rocky Mountain region of Canada, but occurs in 

 southern British Columbia (Agassiz, Sumas, Chilliwack 

 and Burnaby Lake.) 



It is one of the earliest ducks to breed, as young were 

 found in northern Florida on March 19, 1877. 



Winter Range. — The southern range in winter has al- 

 ready been given ; northward the species winters regu- 

 larly to North Carolina, occasionally in Maryland and 

 Pennsylvania ; accidentally in New York and Massachu- 

 setts. In the interior it is found at this season as far 

 north as southern Indiana, southern Illinois and Kansas.
