Turdus Swainsoni, 6 Oporornis agilis
Contopus virens, Fall singing of the 
Vireos. Anthus Ludovicianus (saw one)
1875.
Sept. 11 [September 11, 1875] Clear and very cold ther. [thermometer] falling to 40 [degrees].
Off at 5.30 A.M. meeting Will Stone in the 
swamps, he having missed me at the
house. As large birds were wanting we
went in immediately for specimens but
had very poor luck. The only bird that
I got worth skinning was an adlt [adult male] G.
trichas [Geothylpis trichas] in most beautiful plumage.
Shot and spoilt a Turdus Swainsoni
the first. Saw a little company of Parula
Am. [Parula americana] and shooting one found in [it] almost
destitute of any save pin feathers. Saw also
Oporornis agilis: I have seen several birds
during the week that I referred with some
doubts to this species but this time there
was no mistake; as I got within 6 ft
of the bird: it was uttering its peculiar
and indescribable note (a single loud, sharp
almost vibratory sound that has withal
a sort of metallic ring to it) and another 
in the same thicket kept answering it.
Vireo flavifrons and V. noveboracensis [Vireo noveboracensis] were
both in full song in the pine swamp
and the notes of both but of the latter especially
seemed to me to possess a compass and
sweet completeness lacking in the spring:
possibly the fine, pure air at this season
may assist the effect or lend vigor to the
performer. The sparrows are now moulting
and in very poor plumage. D. striata [Dendroica striata] is
not very abundant yet. Saw two Contopus
virens: it is remarkable that this species
which arrives before E. mininus [Empidonax minimus] should be
the last to leave. The swamps are very dry
and we shall probably have no snipe this fall.
