Flying squirrel
Mass. (Middlesex Co.) [Middlesex County, Massachusetts]
Mel. Lincolnii [Melospiza lincolnii]
May 21 - 1875 My. Canadensis. [Myiodioctes canadensis]
of a fine Pteromys volucella the first
I ever saw alive. He came out of
an old downy woodpecker's hole and
though i shook the tree most violently
he still succeeded in clinging to it
and the moment I stopped would
whisk into the hole to come out again
at the first renewal of the shaking.
Finally he "took wing" and sailed in
a graceful "festoon" to the next
tree a live maple whence I could
not dislodge him, as he flattened
himself against the bark and treated
the shower of old branches & bark which
I pelted at him with serene contempt. 
Finally I shot him but as I got within
a yard or two of his agonized struggling 
among the leaves he found a hole 
among some roots and escaped, much
to my disgust. Saw D. striata. [Dendroica striata]
  May 21 [May 21, 1875] Clear and warm. Wind S.W. [Southwest]. Off after
breakfast, driving up to the willows.
Shot 14 birds with my pistol in 17 shots.
The best were Mel. Lincolnii [Melospiza lincolnii] [female], D. maculosa [Dendroica maculosa] 3 [males],
D. caerulescens [Dendroica caerulescens] 3 [females] 1 [male], My. pusillus [Myiodioctes pusillus] 1 [female], Seiurus
noveboracensis 2 ([male] & [female] etc. Birds were
very numerous and I shot all my specimens
in a little thicket near the road.
The M. Lincolniii [Melospiza Lincolnii] was perfectly silent
and rather shy or perhaps, more properly
speaking, suspicious. In one place I
saw 7 [female] caerulescens and one [male].
Saw a single [male] My. Canadensis [Myiodioctes canadensis]
