LABRADOR CHICKADEE (PENTHESTES HUDSONICUS 
NIGRICANS) IN BOSTON AND VICINITY IN 
THE FALL OF 1916. 
BY HORACE W. WRIGHT. 
AGAIN after an interval of only three years another extensive 
southern migration of Penthestes hudsonicus into New England has 
occurred. The subspecific type of the birds of this incursion, 
Dr. Charles W. Townsend informs me he will discuss in a paper 
which he is preparing for “The Auk.’ Briefly it may be stated that 
he finds all the birds, which have been collected in this latest migra- 
tion and have come under his examination, to be of the nigricans ! 
type and not the littoralis type. My paper on the incursion of 
hudsonicus in 1913,? upon such testimony as is presented in the 
paper, assumed the type of that incursion to be littoralis. It is 
not the purpose of this brief article to assist in determining the 
subspecific type of the visitants in either migration, but to indicate 
by records obtained that the southward movement of hudsonicus 
has been general and as extensive, if not, indeed, more extensive 
than the migration of 1913. With the records which I have 
obtained I am enabled to unite those of a number of other observers, 
who have kindly codperated to further the purpose in view. 
My own records are: Mount Auburn Cemetery, Cambridge, 
October 29, one bird; Middlesex Fells, Melrose, November 7, two 
birds; 25, five birds; Belmont, November 9, nine birds; 20, 
eight birds; December 9, eight birds; January 1 and 3, 1917, 
three birds; Arnold Arboretum, Boston, November 16, three birds; 
December 5, twelve birds; January 8, two birds; Jamaica Plain, 
November 23, one bird. 
Other observers’ records are: Mr. William Brewster, Concord, 
October 7 and 12, one bird; 22, three birds; 23 and 31, one bird; 
November 3, one bird.
