by Mr. Chapman 1 to winter from Florida southward, these 

 statements are misleading, since this vireo winters abundantly 

 in the great swamps which are in close proximity to our coast. 

 That it is a common bird in the months of December, January, 

 and February there is no question, for I have often seen and 

 counted as many as ten individuals in the course of a few hours. 

 On mild days in winter the birds sing with some vigor, but it is 

 not until March that the full volume of song is heard. The birds 

 that winter here begin to moult about the middle of March and 

 usually finish by the 30th of the month. A few remain until 

 the middle of April, but most of them migrate during the latter 

 part of March. 



The Blue-headed Vireo breeds from Pennsylvania to the Fur 

 Countries, and winters from the maritime districts of South Car- 

 olina to Guatemala. 



244. Lanivireo solitarius alticola (Brewst.). Mountain 

 Solitary Vireo. 



The type specimen of this form was taken by Mr. William 

 Brewster at Highlands, Macon County, North Carolina, on May 

 29, 1885, and was described in the Auk. 2 I took a typical spec- 

 imen near Charleston, on February 23, 1885, which antedates 

 Mr. Brewster's type specimen by three months. This specimen 

 is now in the collection of Dr. Arthur P. Chadbourne, Boston, 

 Mass. On February 20, 1886, I secured another specimen near 

 Charleston, which was recorded by Mr. Brewster in the Auk. 3 



This form is larger than L. solitarius, has a larger bill, and the 

 back is usually dark plumbeous instead of olive green. It gen- 

 erally arrives by December 1, but is apparently absent from 

 the last of the month until about February 20, when the birds 

 which have wintered to the southward of South Carolina arrive 

 and remain until March 22, which is my latest record. The song 

 of this form is much richer in tone and volume than that of its 

 near relative , the Blue-headed Vireo . Typical specimens of this large 

 race are very rare, and intermediates are by no means plentiful. 



This vireo breeds in the mountains of South Carolina (Mt. 

 Pinnacle and Caesar's Head), and northward in the Alleghanies to 

 Maryland.
