Concord.- Clear with hot sun and cool N. wind; a September-like day.

  At 7.30 A.M. I found a rather large & interesting mixed
flock of birds in the elms in front of our house. They stayed in
these trees over an hour and with the aid of my glasses I
identified them all positively and made out the following list.
Mniotilta varia, 4 (one ad[ult] ♂[male] in autumn dress), Cornpsothlypis americana 2
(moulting about the head and fore neck), Helminthophila ruficapilla 1,
(apparently ad[ult] ♂[male] in full autumn plumage), Dendroica pennsylvanica 2
(in perfect autumn plumage with olive-green upper and white under parts,
the yellow wing bands and whitish ring about the eye very conspicuous),
Vireo gilvus 4 (three young with very yellow sides, the fourth bird an old ♂[male]
not through the moult but warbling every now & then in low tones)
Sitta carolinensis (♀[female] very ragged & pin-feathery), Icterus baltimore (ad[ult] ♂[male] &
♀[female], both in nearly or quite perfect fall plumage), Contopus virens 1
(silent & apparently young), Passer domesticus 5 or 6, Spizella socialis
4; in all ten species and about twenty-six individuals.
The four species first named were probably migrants which came
from the N. last night and joined the others all of which
have been in the habit of resorting to these trees daily for
the past week or more.

  The male Oriole sang several times in loud, ringing tones.
This is the first time that I have heard the full song for
several weeks although a bird (evidently adult) in the birch
swamp on the Assabet last evening gave most of its sotto voce.
This autumn (or rather late summer) song of the Baltimore
is more prolonged and richer than the ordinary spring fluting
and its effect is heightened by the general silence at this
season. It begins with the normal flute-like song, is
continued by a succession of rich notes & ends, usually, in a low chatter
