Lancaster, Mass
1901.
June-July
  Merula migratoria - Late in May or early in June a Robin built
her nest on the head of one of the columns which support
the piazza roof of Miss Holman's house. The situation was well chosen
for the eaves projected sufficiently to shelter it from the rain while
it was protected from observation by the foliage of a
that was trained around the column. But being directly over
the side exterior to the house there was much passing of people
which at first disturbed the sitting bird sufficiently to make
her leave the nest every time one of us entered or emerged
from the door in question. Before the eggs were hatched,
however, she had learned to disregard us and three young
were successfully reared. They left the nest about the
1st of July. After this the whole family escaped our
observation until the 7th of the month when Mrs. Brewster
saw one of the old birds - presumably the female - visit
the empty nest remaining in it a minute or more.
  We left Lancaster the next morning returning on the evening
of July 15th when we found the female Robin sitting
on the nest - no doubt on a second clutch of eggs. Just
when she began laying them I am unable to state but
the members of Miss Holman's household think it must
have been at about the time of our departure as they
saw the bird sitting in the nest by the middle of
the week (i.e. by the 10th or 11th) they think. This is the
first instance that has ever come under my observation
of a Robin laying a second time the same season
in the same nest. I am very sure that she cannot
have repaired it to any extent for had she gone to
it often for this purpose the fact would surely
have become known to us.
