parts of the plumage are grey. But little is known 
of the habits of this bird, which has been noticed in 
the southern part of Hungary, in Germany, on the 
coast of Dalmatia, and rarely in Italy. It is said 
to feed on winged insects and aquatic worms; but 
its mode of nesting and the appearance of its eggs 
are unknown.

A specimen of this Tern was shot on the 
Shannon, in 1841, in company with the Black 
Tern, with which it was confounded. This speci- 
men was sent, along with one of the latter species, 
to the Natural History Society of Dublin, in 
whose Museum these examples of both species 
are now preserved. ‘The White-winged Tern 
inhabits the bays and inlets of the shores of the 
Mediterranean, and is common about Gibraltar. 
It also visits the lakes, rivers, and marshes of the 
countries in the vicinity of the Alps; and is found 
in Germany, Scandinavia, Dalmatia, &c. The 
food of the White-winged Tern consists principally 
of dragon-flies and other winged aquatic insects. 
Nothing is known either of the eggs or of the 
winter plumage of this species.
