20. Usnea Warbler. Arrived May 2 [May 2, 1916], last seen on the 27th [May 27, 1916]. During the interim
between these dates the species occurred commonly but not numerously no more than
two or three different birds being ever observed in any one day. They sometimes
visited blossoming apple trees in the orchard or the big elms in our door yard but
were noted oftenest in mixed woods especially those along the Run.

21. Yellow Warbler. Heretofore we have always had at least one pair of Yellow
Warblers and sometimes two, nesting in cultivated shrubbery close about the house.
This year a [male] was noted there on May 5 [May 5, 1916], 6 [May 6, 1916], 7 [May 7, 1916], 8 [May 8, 1916], 22 [May 22, 1916] and 23 [May 23, 1916] which another,
with different type of song, was heard on May 27 [May 27, 1916], June 1 [June 1, 1916], 2 [June 2, 1916], 6 [June 6, 1916] & 7 [June 7, 1916], but both
were apparently unmated and merely wandering bachelor birds although one or the
other may have had a spouse & nest in Mr. Howe's grounds where I heard the 
song of a male on May 28 [May 28, 1916] & June 18 [June 18, 1916]. Another heard at Flint's Bridge on
June 28 [June 28, 1916] completes my Concord Region record for the present year.

22. Black-throated Blue Warbler. Of normally sparing occurrence during May
migration when I noted a [male] on the 13th [May 13, 1916], two [males] on the 14th [May 14, 1916], one on the 19th [May 19, 1916], one on
the 20th [May 20, 1916] and a [female] on the 21st [May 21, 1916]. One of these birds was met with among red cedars
near the foot of our lane, all the others in the Run leading thence to Pulpit rock.
The males sang freely, at various times of day.

23. Yellow-rumped Warbler. First noted on April 30 [April 30, 1916] when a single [male] was
seen. During May 2 [May 2, 1916] there were not less than 50 birds, mostly males,
scattered about in apple trees, oaks & hickories near our farm buildings. As
they flitted hither & thither in small, loose flocks their low-pitched, trilling
songs came pleasingly and almost ceaselessly from every direction. No more
than a dozen remained over the next day and after that only a few
stragglers were seen the last, a [male] & 2 [females], on May 21 [May 21, 1916]. A [male] singing all
day long near our house on the 6th [May 6, 1916] had a peculiarly sweet, full &
loud voice.
