472 LARGE-BILLED GUILLEMOT
|I have never observed this bird on any part of the coast of our
Middle Districts, and, although I was told that it not unfrequently
occurred about the Bay of Boston, I failed in my endeavours to procure
it there. The specimen from which my figure was made was sent to me in
ice, along with several other rare birds, from Eastport in Maine. I
received it quite fresh and in excellent plumage, on the 18th of
February, 1833. It had been shot along with several other individuals of
the same species while searching for food in the waters of Pasmaquody
Bay, which were then covered with broken ice. Its flight was described
by Mr. CURTIS, who sent it to me, as similar to that of the Foolish
Guillemot, with which it associated. No other information was
transmitted, excepting that it dived and swam like the other species. I
afterwards sent the skin to my friend the Rev. JOHN BACHMAN, in whose
collection it remains.
No individuals of this species were observed by my party on our way to Labrador; and as the Foolish Guillemot was abundant on the coast of that country, I concluded that the Thick-billed Guillemots which visit our eastern seas in winter, set out for the far north at an earlier period than the others. I am indebted to Mr. HEWITSON of Newcastle, author of the "British Oology," for a description of an egg of this bird, which is in the valuable collection of the Messrs. HANCOCKS, who procured it from Greenland. It measures 3 1/8 inches in length, by 2 1/8 at its broadest part, and is of a bluish-green colour, streaked and spotted with black or very dark umber.
Male, 18 1/2, 30.
Occasionally procured in Maine. Not very rare off the coast of Nova Scotia. Breeds from Hudson's Bay to the Arctic Seas.
