Concord, Mass.
1912.
April 1 to
July 1.

  Cotile riparia. - Fair-sized breeding colony in bank on Bedford Street near
Catholic Cemetery, another one in bank near town centre ([?] sand bank)
More on Dakin's Hill or near Peterson's. Very few seen along river after migration. 
  Spizella pusilla. Very scarce this season. Must have suffered heavily from
cold winter in south. I doubt if any bred on our land although I heard 
one singing in or near our berry pasture May 3-23. One heard in Howe's
pasture & another at rear of Everett Mason's, Bigelow Road, on June 3 [June 3, 1912].
  Melospiza melodia. Comparatively scarce during migration & later. Must
have suffered in South. Not over 20% of usual number survived to breed. At the Farm had none near house & only 2 males sang in Berry Pasture
   Pipilo erythrophthalmus. - This species also unusually scarce. Only one
bird noted during breeding season. He sang in Berry Pasture through June.
  Hydemelis ludoviciana.- Less numerous than usual. One pair at Farm, one
at Ball's Hill. Latter built nest in birch E. [east] end of hill but Jays (?) raided it.
  Passerina cyanea. Three [males] singing through June at Farm, one 
near house, one in Berry Pasture, one in Birch Field.
