freely or so viciously although they are very annoying
at times by getting into one's eyes, nose & ears. At least
I have no doubt that the birds feed chiefly on these
insects for they were the only ones that I could 
see and the air was filled with their swarming
legions.
  The arrivals for the day were D. caerulescens, G. trichas
V. olivaceus, V. flavifrons & Habia ludoviciana mentioned
above with Galeoscoptes carolinensis (male singing at Davis's Hill)
and Dolichonyx orzivorus (male singing on West Bedford 
side of the river).
Arrivals.
  I spent the entire forenoon in the woods just
behind Ball's Hill watching the swarming Warblers
& cutting down trees along a new wood path.
In the afternoon I visited Davis's Hill where
I found about a dozen birds including the Cat bird,
a Towhee, a Yellow Warbler & a few Yellow rumps.
  In a small pine standing alone in an exposed
part of the hillside I discovered a Blue Jays  nest
over the edge of which projected the tail of the
sitting bird. I did not disturb her or approach
the nest nearer than 15 or 20 yards (Nest empty & abandoned a few days later)

on nest.
  As I was sitting on a bank by the river a
large Mink crossed the path within 15 yards of
me coming from the hillside. I went at once to
the spot but did not see the arrival again although
the bush was trim & there seemed to be no places where
a mink could hide.
