1893. 
July 13. 
Mass . Nest. 
When the Cooper's Hawks were frequenting the pines near 
the Glacial Hollow last April, I noticed two large nests in 
these trees. Pat climbed to one but found that it was a 
Squirrel's nest. The other, ’which was further to the north- 
ward in a tree that stands at the foot of thd slope next the 
swamp, we did not examine as it did not look very promising 
and the Hawks had apparently deserted the woods at that time. 
I have seen them there at rare intervals since but felt cer- 
tain that they were nesting at some distance beyond my limits. 
As we were passing through the woods this afternoon, however, 
we started one of the birds from the pines very near the 
second nest and on examination found the ground beneath it 
literally white with droppings of the birds. There were also 
the shells of a recently-hatched egg directly under the nest. 
It is probable therefore that the birds hayfe been there the 
whole season and have put me off the track by their remarkable 
silence and elusiveness. I have not heard them scream since 
April .
