BIRDS OF DURHAM AND VICINITY.

Nettion crecca. European Teal. 
138. 
This is another trans-Atlantic fowl that sometimes inadvertently 
comes to America. Its general coloration is very similar to that of 
the Green-winged Teal, but it differs in lacking the conspicuous white 
bar on each side of the breast. 
It is highly probable that the Canvas-back appears here at irregular 
intervals, in autumn at least. 
Somateria mollissima borealis. Northern Eider. 159. 
This is a northern form of Eider, breeding in Greenland. It can 
be distinguished from the American Eider only after capture. The 
two projections of the horny bill-sheath, toward the top of the head, 
are parallel, narrow, and acute, on this species, in contrast to those on 
dresseri, which are divergent, broad, and rounded at the end. 
Chen hyperborea nivalis. Greater Snow Goose. 169a. 
This is a rare visitant to New England from the interior. Adults, 
excepting their black primaries, are entirely white. 
Chen cserulescens. Blue Goose. 169. i 
This species nas been taken once or twice in Maine. 
Anser albifrons gambeli. American White-fronted 
Goose. 171a. 
Another possible visitant from the interior. Only a few have been 
taken in New England. 
Br anta nigricans. Black Brant. 174. 
The Pacific form of our Brant. It is accredited to southern New 
England, and it is not impossible that it may be found here. It is to 
be distinguished from our Brant by a broad white collar, broken be- 
hind in the middle of the neck. 
This is a casual wanderer from the south. In October, 1858, an 
adult specimen was taken at Alton by Dr. Charles Palmer of Ipswich, 
Mass. (American Naturalist, i87i,p. 120.) It has also been taken 
several times in other New England states. 
Aythya vallisneria. Canvas-back. 
147. 
Odrer HERODIONES. 
Plegadis autumnalis. Glossy Ibis.
