  Sialia sialis. - Judging by conditions here the Bluebirds
must have suffered a heavy loss in the South last winter
as they did in the winter of 1894-5. The only breeding
pair I know of in our neighborhood reared 3 or 4 young
in a box in Bensen's pasture. Besides these I saw an adult [male]
on June 3 [June 3, 1912] near Everett Mason's & an old bird with one young
on June 23 [June 23, 1912] near Red Bridge. Scattered birds were
heard calling in the air on other occasions, in other 
places. Faxon saw only one bird during a week in 
May from Concord to Maryland. For the first time in
my experience there was no nest at our farm or
in the Ritchie place.
  Galeoscoptes carolinensis. In usual numbers. One pair
nesting behind house at Farm, another in Berry Pasture,
a third near Mrs. Harris' house, a fourth in
flooded thickets opposite Ball's Hill
