E. Watertown, Mass.
1900.
June 5
  Visited the hog's back ridge opposite the Arsenal
at E. Watertown this forenoon to get some photographs.
The weather was clear & still and the birds were
singing well. I heard Robins, Cat-birds, Yellow Warblers,
Redstarts, Maryland Yellow-throats, Song Sparrows, a Wood
Pewee, a Yellow-throated Vireo and an Indigo bird.
Bronzed Grackles in small numbers were flying to
& from their nests in some tall pitch pines on the 
top of the ridge. In an oak I saw a Blue Jay
feed its mate precisely in the same way as at
Concord a week or two ago, the bird receiving the
food crouching, fluttering her wings feebly and making
a low chirping sound like a young bird. No nest 
was visible & I cannot quite understand why
the female (?) should have been fed when she was not sitting.

  Warbling Vireos were singing in or near silver leafed 
poplars along the streets behind Mt. Auburn where
I used to find them thirty or more years ago.
