THE PHILADELPHIA VIREO IN NEW ENGLAND.—The increase and decrease of certain species in given localities is becoming a subject of much interest, instances of which are cited every year. A single specimen may be captured in a locality far from the usual habitat of its species, where it may not be seen again for years, or it may gradually increase and later be found as a regular autumn migrant, though not detected in the spring, and vice versa. The above-named species was first given as a New England bird by Prof. Charles E. Hamlin, based upon a specimen which he captured at Waterville, Me., May 21, 1863. For the next nine years it escaped the notice of our collectors, when during a collecting trip at the Umbagog Lake, Maine, I procured a specimen on June 3, 1872, and on the following day, in company with Mr. Wm. Brewster, obtained two more. In a communication from Geo. A. Boardman, Esq., he states that on June 2, 1872, he obtained a female at Calais, Me., the only one, however, which he has met with. We did not hear of the Vireo again until September, 1874, when Mr. Brewster took six specimens at Lake Umbagog. On September 11, 1875, I procured a female at the foot of Ripogemus Lake, a beautiful sheet of water situated about one hundred and fifty miles northeast from the Umbagog Lake, and observed two others. There was an immense migration of Warblers, Sparrows, and other species on that morning, and the specimen taken was in company with the Red-eyed and Yellow-throated Vireos.* All these specimens were undoubtedly on or near their breeding-grounds, and although but few pass through the coast States, yet it is strange that the species should have escaped the notice of the many watchful collectors of the present day until Mr. Brewster procured a specimen in Cambridge, Mass., on September 7, 1875 (see Bulletin No. 1, p. 19). Three specimens were taken during the first week of June, 1876, at Lake Umbagog, in which locality it now must be considered as a summer resident.—RUTHVEN DEANE. * This is the most northern locality in Maine at which I have known the Yellow-throated Vireo to occur.
