Late breeding of C. stellaris [Cistothorus stellaris] - Evening
flight of Dol. orizivorus [Dolichonyx oryzivorus] 
MASS. (Middlesex Co) [Middlesex county, Massachusetts]
1875
Aug. 9 [August 9, 1875] accounts for the fact that the eggs are
so rarely taken - the bird being evidently
an even later breeder than the Chrysomitris.
  August 10 [August 10, 1875] Clear and hot. Went up to the swamps
again this P.M. with young Danolson.
Waited near Block is. [Block island] for the evening flight
of birds and saw them come again in
extraordinary numbers. The marsh wrens (C. stellaris [Cistothorus stellaris])
were singing steadily on all sides and
I hunted a long time in rain for a
nest among grass as tall as myself. The
bobolinks come in by thousands to roost
in the fresh water meadows, after spending
the day on the salt marshes. Wanting some
specimens we concealed ourselves in their
line of flight and killed 8 or 10, I
making two double shots. They fly
much earlier in the afternoon than the other birds which
roost in the maple swamp adjacent.
I think the rails have nearly if not all
left as we searched very closely for them
without flushing a single bird.
  August 13 [August 13, 1875] For the last three or four days I have
heard the sharp chirp of Seiurus noveboracensis
in our garden and today I started one
up from under the sink spout. They pass
most of their time however in a piece of tall
corn where they search for food in the earth
kept moist by its luxuriant shade, and
judging by their calls there must be a
number of them in the place. Hummingbirds
