Concord, Mass.
  A Pied-billed Greebe, a fine old bird in full breeding
plumage with black throat and gray head, spent the
day in the river in front of the cabin diving at
times for food in deep water about mid-way of the
channel but for the most part cruising warily about
turning its head continually from side to side &
evidently keeping a sharp watch for danger. I watched
it at intervals through my glass. It is the first
Pied-bill that I have ever seen in Massachusetts in
spring.

  During a short walk which I took behind Ball's 
Hill in the forenoon I heard what I at first
supposed to be a Jay making a succession of rather
low, mewing calls apparently in rude imitation of the
cry of the Red-Shouldered Hawk, that when I finally
caught sight of the bird sitting in the top of a 
birch on the edge of Holden's meadow I saw at once
that it was a Hawk of medium size. The next
instant it flew and made off at great speed in
the direction of Davis's Hill when the short pointed
wings and rapid nervous flapping alternating with periods of scaling identified it
at once as a Cooper's Hawk, the first that I have
observed this season.

  Still another Hawk which crossed the river
from Ball's Hill to the Bedford shore when it 
alighted in a large oak passed me completely
although I had a good view of it through
a strong glass not over 100 yards away at first
with the light & other conditions favorable in every way
