  A Partridge was drumming this afternoon in the
Barrett run and another in Prescott's pines near the
road to the Gun Field, both on stone walls. Gilbert
heard a third in the Blakemore woods. I think
that the bird in Prescott's pines was the same that
I heard yesterday at the north end of Davis's swamp
(where the drumming stand is a small log) and I
also believe that the Blakemore bird is the one we
hear so frequently at the east end of Ball's Hill.
In other words I think that each bird has two
drumming stations.

  A few Robins came to the spring roost in the
dense pines behind Ball's Hill this morning. All
appeared to be males and there was, as usual, much
singing and calling. I was astonished to hear one bird
sing on wing. I heard him in the distance at first.
When he appeared he was flying in the usual manner
but rather slowly. He continued his song without the
slightest break when and after he reached his perch
on the topmost spray of a tall pine. There was
nothing peculiar about the song. Evidently it was
not a real flight song but the bird was simply
so full of his [?] that he could not wait until
he reached the end of his short journey.

  There was a solitary Yellow Palm Warbler about the
cabin yesterday and again this morning. Gilbert saw
a single Yellow-rump on the 17th. I miss sadly the
large mixed flocks of the Warblers we usually 
see at this season and fear that nearly all must have
perished in the south last February.
