DUCKS. 63 
As the American Green-winged Teal (Anas caroli- 
nensis, Gmelin) is believed to have occurred in this 
country, it may be well to remark that it differs 
from the European bird in wanting the white streak 
which extends from the bill over the eye in the latter ; 
and the white line below the eye is also nearly absent, 
being very indistinctly marked. It is also without the 
cream-coloured band on the scapulars, while across 
the shoulder there is a distinct transverse bar of white, 
no trace of which is to be found in the European bird. 
Mr. J. H. Gurney, jun., informs me that two instances 
are known to him of the occurrence of the American 
Blue-winged Teal (4. discors, Linneus) in England ; 
and Mr. R. Gray has recorded the capture of one in 
Scotland*; but as so many foreign wild fowl are 
annually imported for our parks and ornamental 
waters, it is almost impossible to say whether the 
solitary examples found at large from time to time 
are truly wild or escaped birds. 
GARGANEY. Querquedula circia (Linneus). 
A spring and autumn migrant, occasionally remain- 
ing to breed. The nest is reported to have been 
found in Norfolk, Cambridge, and Huntingdon. It 
is of rare occurrence in Scotland; and but very few 
examples have been met with in Ireland. 
POCHARD. Fuligula ferina (Linneus). 
A winter visitant, occasionally remaining to breed.
