Concord, Mass.
1912 
April 1 to 
July 1.

  Harporhynchus rufus. Exceedingly scarce after the migration
passed. During its continuance (May 1-14) I heard or saw a
few birds at Ball's Hill. Afterwards I located but one
which sang freely from May 12 to June 25 in Mr. Howe's 
pasture at the rear of Holden's Hill.
  Sitta carolinensis. - On March 31st [March 31, 1912] and again on April 17 [April 17, 1912]
I saw a pair of Nuthatches in the elms that shade our farm
house. On April 28 [April 28, 1912] I noted a [male] at Bensen's and on June 23 [June 23, 1912]
heard the call of a bird at Dr. Emerson's place. Quite
evidently there was no nest at or very year our Farm this
year. Why they should have ceased to build them after continuous
residence for many seasons I cannot imagine.
  Certhia americana. No Creepers noted this spring by me
anywhere in Concord or elsewhere for that
matter. I feel they must have suffered severely
in the South last winter with the Bluebirds, Robins etc
