444 Sherman, Brewster's Warbler in Massachusetts. [oct 



When within a short distance of it, we saw, in a mixed flock of 

 migrating warblers, either the same bird or one in similar plumage. 



A few days later a pair of Brewster's Warblers were reported 

 nesting in the Arnold Arboretum. I did not see the birds or the 

 nest, but I was told by Mr. Charles J. Maynard and others who 

 did see them, that the nest contained five eggs, all of which hatched. 

 Dr. Faxon reported the young to have left the nest when seven days 

 old. Mr. Maynard sent me a water-color drawing of the female 

 and young, which he made at the time. This female showed an 

 extensive, nearly black throat patch, also a large yellow patch 

 in the wing. 



During the spring of 1908, a pair of Brewster's Warblers again 

 built in the Arboretum near their old site, but on the other side 

 of the road. This nest was found by me after having been given 

 a clew by Mr. John Carver of its supposed location. It was 

 placed a few inches from the ground and rested in the center of 

 the upright shoots of a young cornel bush. Eventually it con- 

 tained four eggs. Three disappeared, leaving one on which the 

 female sat for several days but finally abandoned it. The last 

 visit I made to the nest, which was some time later, showed the 

 egg still there. I have since been told that the nest is now in- 

 cluded in the Harvard University Collection. 



Mr, Carver told me that the birds started to build again, a few 

 feet away, but that they did not complete the nest. 



This female, of which I made a water-color drawing, showed a 

 dark dusky throat patch, not clearly defined at its base, but 

 blended into the pale gray of the upper breast. It was blackest 

 at the base of the bill and at the center of the throat. 



The black line through the eye was broader and extended back 

 farther than did that on the Brewster of the preceding year. 

 She differed also in showing two broad yellow wing-bands. 



June 5, 1910, my son's attention was attracted to a male Golden- 

 winged Warbler carrying nesting material not far from our house. 

 He told me about it and took me to the place that afternoon. 

 We soon found the male, a beautiful specimen, easily recognized 

 and distinguished from other male Golden-wings by his jet black 

 throat patch which extended up and back on either side of his 

 neck. This took away its usual triangular shape and gave it 

 rather the appearance of a bib.
