lining consisted of fine black rootlets and black and white hairs, 
the walls also not being so thick as in the previous one. In addi- 
tion to this difference in the nests the two sets of eggs were not at 
all alike, the first one being rather pointed and minutely spotted 
size .70 X .51, whilst the second one was more obtuse and boldly 
spotted size .66 X .50. The female on being flushed behaved 
exactly in the same manner as before dropping to the ground and 
when some little distance away from the nest rising above the 
underbrush into the lower branches of the adjacent trees, where she 
preened her feathers and flitted about most unconcernedly, in 
marked contrast to the behavior of the Redstart, Myrtle, Magnolia 
and Chestnut-sided Warblers, all of whom show great concern when 
flushed from their nests after incubation has been in progress a 
few days, which was the case in the above instance. As regards 
the male he behaved as before not putting in. an appearance, 
although on the day of finding the nest I located one (presumably 
the male of this pair) singing in the tree tops some two hundred 
and fifty yards away. Certainly in my experience the behavior of 
the male of this species is not very complimentary, but I have to 
write as I found him. | 
After locating this second nest at such a late date, and apparently 
belonging to another pair of birds, I made renewed efforts to try 
and find a third one, but without success, although on August 1 
I found a female feeding a young bird just able to fly, at a spot some 
seventy-five yards north of the first nest, and on this occasion the 
male put in an appearance for a brief period only, but made no 
effort to feed the young one. Probably these were the advance 
guard of the fall migration and have no bearing on the matter, in 
which case it is of course possible that the two nests and sets of eggs 
although differing so greatly may have belonged to the same pair of 
birds, in favor of which my inability to find a third nest and 
the unusual behavior of the male in keeping out of the way in 
both instances would seem to point. As regards the Black-throated 
Green Warbler I found the parent birds feeding young on the 
ground on June 28, and also located two empty nests, thus definitely 
adding it to the breeding list, so that there only remains the Black- 
burnian Warbler of the summer visitants whose nest, eggs or young 
I have so far failed to find. In conclusion I may mention that I
