  There are at least two and I think three male
Wood Thrushes settled in our Run. Two were singing there
this morning within thirty yards of each other near the
(?). As I passed on I heard what I took to be a 
third at the foot of the Run but one of the birds heard
before may have moved on as I moved.
  A Pine Warbler that has been frequenting the cluster
of pitch pines in the Run for the past month has 
two distinct songs. One of them is the normal song
of the species but if anything fuller, louder and
more melodious than is usual. The other song is a
short, flat, dry, woodeny trill positively indistinguishable 
by my ears from that of a Junco & a poor singing
Junco at that. I heard the bird change from one 
song to the other several times this morning.
  Two male Bobolinks spent the whole of yesterday
and today in the meadow across the road from the
farm house. They kept together the whole time pushing
within a yard or two of each other in the tops of
leafy elms & apple trees and one following the other 
when it took wing. Their singing was louder, more
continuous and more rollicking than any Bobolink
music I have heard for years. Not once did they
sing together but one would usually begin as soon
as the other ceased. Thus they kept up an almost
continual flood of music. I feasted my ears on
it for nearly half an hour. They kept it up nearly
all day. I saw no female. The males acted as 
if they were close friends rather than rivals.
