26. Dendroica caerulescens. - A [male] juv. [juvenile] seen in mixed flock in Birch Field on
Septemer 21 [September 21, 1913]. On the 26th [September 26, 1913] I was pruning an apple tree in
the orchard when a [female] appeared directly over me and presently
tried to perch on the terminal and still moving end of
my pole prunes which seemed to excite her curiosity greatly.

 27 Dendroica coronata. - Arrived September 12 [September 12, 1913]. Present in the largest
numbers Sept. 24 - 25, frequenting gray birches in company
with D. striata [Dendroica striata]. Common from this time up to October 16 [October 16, 1913]
after which comparatively few were noted, the last on
November 13 [November 13, 1913]. During this as in many a previous
autumn I frequently saw Yellow rumps, to the number
of a dozen or more, accompanying flocks of Bluebirds flying
over wide open fields & meadows sometimes rather high
in air, usually bringing up the rear of the
loose, struggling procession of birds and calling quite
as freely as the Bluebirds. Not infrequently the 
flock would contain more or less Chippies, also.
When the dew-soaked roofs of our farm buildings were
steaming in the rays of the early morning sun they
were often resorted to by Yellow rumps who hopped
all over them & peered in under the eaves or [?]
on fluttering wings to do so, apparently seeking insects
there.

28. Dendroica maulosa. Only one record, that of a [female] seen among
gray birches, in Birch Field, on September 24 [September 24, 1913].

29. Dendroica pennsylvanica. A young bird in big elm near barn at
Farm on August 31 [August 31, 1913], another in oaks behind barn on September 2 [September 2, 1913]
& an adult [male] (showing wide chestnut stripes on sides) in Birch Field
on September 21 [September 21, 1913], all three in company with Warblers of other kinds.
