graphed after it had eggs, as it was rather peculiar, being 
constructed entirely of, and lined with, pine needles. I also 
intended to photograph the third nest, with the bird on it, 
as she was very tame; but on my third visit it had been 
robbed, as was the one I photographed. I visited the one by 
the path several times, but never stepped out of the path , 
and did not photograph it, and was gratified to see the eggs 
hatch out and the young grow to be large enough to leave the 
nest. One nest which I found, that of a brown thrush, two 
feet high in a blueberry bush, was robbed when it had young 
half grown.” 
If foxes follow the tracks of people who find birds’ nests, 
then bird study and photography may prove dangerous to 
the birds. 
Mr. C. E. Ingalls once intimated to me that he had some 
reason to believe that a fox had followed his tracks to a 
bird’s nest. In response to a written inquiry he sends the 
following : “ I had at one time under observation the nest of 
a meadowlark. One afternoon about sundown I passed the 
nest with its full complement of young a day or two old, 
with everything looking favorable for a successful develop- 
ment. I passed from the meadow where the nest was situ- 
ated up to a hillside adjoining, and in full view of the loca- 
tion of the nest. I seated myself upon the ground to watch 
some spotted sandpipers that I felt sure were nesting beside 
the brook flowing through the meadow, when I saw a fox 
come to the lower end of the meadow and begin to hunt, as 
I supposed, for mice. In the course of his quartering over 
the ground he apparently stumbled onto my lark’s nest, and, 
as he became aware of its proximity, he pounced sharply to 
one side right into it. I jumped to my feet and shouted to 
him, and ran towards the nest, while Mr. Fox loped airily 
and quickly to the woods. When I arrived on the scene, two 
of the young were gone and one other lay about a foot from 
the nest, dead. One pleasant evening in May I was sitting 
on a log near the edge of a piece of mowing land, where it 
joined some scrub on the edge of a wood. . . . While wait- 
ing, I saw a fox on the edge of the grass land, mincing along, 
in no hurry, and evidently hunting for mice or grasshoppers,
