Merula migratoria
1907,
August 5.
Lake Umbagog.
  In my boat house at Upton I found, to-day, a Robin's
nest built on cross timber inside the building to which access can
be had by a bird only through a broken pane of glass. This, at
least, is the case at present but the nest is not a fresh one and
may have been there several years. The mice have filled its cavity
with cotton waste.
