Robin relining nest for second laying.

  The young left on [one] of the Robins' nests under the eaves on
the front of our house on May 26. Since then I have seen
them with their parents about the place almost daily but
not until to-day have I seen either of the parent birds
at the nest. The female came to it with a bill full of
dry grass while I was dressing this morning, however, and
after that I saw her make repeated trips of the same
kind. Evidently she is relining the nest preparatory to
laying a second clutch of eggs in it.

Unusual abundance of breeding Blackburnian Warblers

  Blackburnian Warblers are breeding as numerously on
our place here this season as they do in the Maine woods.
There are two males singing in Pulpit Rock woods, one in
Prescott's pines, on [one] on Davis Hill, one on Pine Ridge and one at
Ball's Hill. Never before have I known so many here
in summer. I attribute this increase to the crowding in of
birds driven from nearby localities by cutting or thinning of the
pine woods which has been so general in Concord of late.
