Autumn song of Swamp Sparrows

beautiful song, repeating it six or eight times at short
intervals. It consisted of the ordinary trill preceded, as well
as followed by a number of additional notes some of which
were exquisitely liquid and tender. This song, which the
Swamp Sparrow gives not infrequently in the summer and
early autumn, is not unlike the flight song used in May 
and June and it may be essentially the same although as
I listened to it attentively this evening I thought it
appreciably different and decidedly superior to anything one 
ever hears from the bird in spring. As far as I could
make out the particular bird to which I have just referred
was perched among the reeds every time he sang.

Marsh Wren

  The Marsh Wren was in a bed of flags at the edge of
the Lagoon. For sometime he remained concealed uttering a low
cac which I mistook at first for that of a Red-wing. At
length he showed himself within a few yards of me and I
had him in plain sight for several minutes during which, to
my surprise, he did not once cock up his tail - a very 
unusual omission.
