More migrants arrive.
Western Palm Warbler

  A second and lesser flight of northern bred
Warblers arrived last night which was calm, warm and
clear although foggy along this river valley. Most of
these birds were Black-polls. In company with
four or five of these in white pine woods on the
crest of a ridge Smith O. Dexter & I found a
Western Palm Warbler this afternoon. It behaved
very oddly, keeping 30 or 40 feet above the ground near
the tops of the pines and not once wagging its tail
during the entire time (certainly two minutes)  that we had
it under observation. Nevertheless I feel sure that our
identification was correct for we both made out all its
characteristics of color & marking except the yellow under
the coverts & that Dexter saw although I did not.
It certainly had no yellow on the under parts except
on the tail coverts & perhaps on abdomen, also.
