1902.
June 21
(No 2)
bird is without doubt the same that I heard
in practically the same place on the 15th of this
month and it may also be the same as the
one that was singing on Davis's Hill on the 11th.
So far as I can ascertain there are no Blackburnians
in the pines near Pulpit Rock this summer (I heard
one there at migration time) although there were two
males singing there in June 1900 and one last year.
No doubt there are one or two pairs breeding in
Lawrence's woods but I have not been there this
season.
Blackburnian Warblers
  As I was following the path which leads from
the Barrett orchard to Birch Field walking noiselessly
over the water-soaked pine needles I surprised a
Cooper's Hawk which was perched on one of the
under (dead) branches of a small pine directly over
the path. Instead of flying away from it came
directly towards me passing within ten yards & giving
me a clear view of it. It looked like a young bird
but was probably an immature female. It is actually
the only Cooper's Hawk which I have seen in this
part of Concord for three or more years. When it
first took wing several small birds (Black-throated 
Green Warblers I thought) in the pines near where
it had been sitting set up a low shrill te-tee-tee-
tee-teeing which they continued until it had flown
out of sight. This sound seems to be made by
a number of Warblers as well as Sparrows whenever
they are alarmed by the presence of a Hawk.
