1916.

55. Vesper Sparrow. First noted on April 5 [April 5, 1916]. Afterwards
present in normal numbers during the entire season, throughout
all their ancestral haunts in our neighborhood. Singing
freely at all hours up to close of May after which they were heard
less often, usually at morning & evening only, until the first week of
July when the second song period began with renewed vigor and
obviously improved sweetness and finish of their delightful chanting,
in the fields that had "release from the sickle and the rake" 

56. Grasshopper Sparrow: Listed herein solely on authority of
Mr. Dexter who, moreover, noted only a single bird - a [male] heard
singing in June not far from the Baker Farm. From all that I can
learn of its present and recent local status the species would seem to 
have well-nigh ceased to frequent any part of the Concord Region in 
summer although not uncommon there formerly.

57. Henslow's Sparrow. A male singing in June, in a grassy
 meadow on the Wilfred Wheeler farm not far from the Fitchburg R.R.
Station, was reported to me by Mr. Dexter. So far as I am aware no
other bird of its kind was noted within Concord limits this season.

58. White-crowned Sparrow. Two handsome plumaged birds together in
our Farm lane on May 13 [May 13, 1916]. One uttered every now and then a sweet, plaintive
song beginning with two notes very like a Vesper Sparrow's opening ones &
followed by have [half] a dozen more suggestive of those of the Tree Sparrow. My
crude, whistled imitation of them was often promptly answered by their author.
On the 14th [May 14, 1916] a single bird, also in the Lane, sang at intervals all day long.
His song wild & plaintive reminding me of a Meadow Lark's. He also uttered
the whit call and a faint, lisping chirp common to most Sparrows.
It was, no doubt, the self-same male that continued to haunt the
