This species has increased grestly in numbers 
during the past ten years in the region about Concord and 
at Pill*s Hill it now breeds abundantly. -e found no 
leas than five nests there this season. T o were begun 
on the morning of May 17th and two on that of the 19th, 
while the fifth was a parently completed on the latter 
date* Two of the five alre hatched and reared their 
young successfully, the other three nests were destroyed 
soon after the eggs were laid. Gilbert took some careful 
i 
notes respecting one of these nests, from which X have 
compiled the followings 
At a 1 ’ ' h '.on 7fr -y 17th i female 'v.dstart 
brought a long, trails nr rut, silky-looking fibre ap- 
pare tly that of a milkweed stalk -- to a gray birch in 
front of the cabin and, placing it at the intersection- 
of rather stout branch with the. main stem, began moving 
it about until its position suited her, when she pressed 
it down firmly by rubbing it with the side of her head 
which she turned slcsrly from side to side. This was 
i 
literally the first bit of nest material that was put in 
the crotch. Many others of an apparently similar kind 
w-re brought during the forenoon and treated in the same 
•way, although the bird had to use her bill rather vig¬ 
orously in tamping some of the more refractory ones into 
pi ce* Che worked busily and steadily until noon^when the 
foundation of the nest was finished.
