APPENDIX 167 



Winter Range. This species is accidental in winter in 

 the West Indies (Jamaica), rare in the Bermudas and rare 

 in central Florida (Gainesville) and also in Alabama. 

 From Georgia northward it is more common, and from 

 North Carolina to New Jersey it is one of the abundant 

 winter ducks. Black ducks, including both A. obscura 

 and A. rubripes, are abundant at this season around Long 

 Island and on the shores of Rhode Island and Massachu- 

 setts, but although a few A. obscura winter in Massa- 

 chusetts, the greater number are A. rubripes. West of the 

 Alleghenies there is uncertainty as to which form pre- 

 ponderates in winter. A. obscura is a tolerably common 

 winter resident of Louisiana, but A. rubripes reaches Ar- 

 kansas, and one form or the other winters as far north as 

 southern Ohio, southern Indiana and southern Illinois. 

 In migration A. obscura is rare west to eastern Nebraska 

 (Fairmont, Gresham, Calhoun) and eastern Kansas 

 (Reno County, Wichita and Lawrence.) Notes on the 

 migration of this species are for the most part included 

 under those of A. rubripes. 



Anas obscura rubripes Brewst. Red-legged Black Duck. 



Breeding Range. As stated under the last species, a 

 breeding duck from Okak, northeastern Labrador, is con- 

 sidered intermediate between this form and A. obscura, 

 while the bird breeding at Ungava Bay is A. rubripes. 

 This Ungava Bay record seems to mark the northeastern 

 limit of the species so far as reported. Thence the species 

 extends west to Hudson Bay, as far north at least as Fort 

 Churchill, and is rare or accidental west to Manitoba 

 (Long Lake; Lake Manitoba, Oct. 28, 1900; Delta, Sept. 

 4, 1902, September, 1903; St. Marks, two, October, 1902),
