GULL-BILLED TERN. 
Sterna Anglica. Montagu. 
The naturalist, whose name is attached to the specific 
appellation of this bird, was the first who distinguished it, 
in the supplement to the “ Ornithological Dictionary,” from the 
Sandwich Tern, which it much resembles in some stages of its 
plumage. 
Some doubts have been entertained whether the S. Anglica of 
Montagu and Temminck are synonymous ; for our own part, we 
think, without a cause. Mr. Jenyns, in his “ Manual of British 
Vertebrata,” and Mr. Selby, in his “ Illustrations of British 
Ornithology,” concur in thinking them so. 
In summer, the Gull-billed Tern has the crown, occiput, and 
upper part of the neck, black; upper plumage, light blueish 
grey ; lower plumage and tail, white ; tips of the quills, and the 
half of the inner webs, next the shafts, grey, darkest at the tip.
