Cambridge, Mass.
1902
July
  With the exception of a single day spent at North Scituate
and several Sundays at Concord I was in Cambridge through the 
entire month. The weather has been almost uniformly cool
and during much of the time uncomfortably so and there have been
very many cloudy days as well as frequent rains but almost
no thunder showers. The birds have sung less freely than usual,
especially during the latter half of the month. No northern species
have appeared and I do not think that many of our local
birds have departed for the South.
  The following species have been noted in out garden: -
  1. Turdus fuscescens. - One in our mulberry tree on the afternoon of the
14th. I had a good view of it & am sure of the identification.
  2. Merula migratoria. - Constantly present feeding on cherries & mulberries. 
Not often seen on the lawn after the middle of the
month. The birds (all young in spotted plumage) came
down one of our chimneys, each by a different flue, and
were found dead or dying in closed & unused rooms.
On the evening of June 16th (at 8 o'clock) Gilbert started
about 25 Robins from the lilacs immediately behind
our house. I was away during that month but
returning on the 30th found that the birds has established 
a small roost in these lilacs to which they have
come regularly, and in ever increasing numbers, through
the present month (July). As the bulk of the flight arrives
at a time when we are taking supper at a neighbor's I
have not been able to follow it closely but the birds seem
to come from every direction and from considerable distance.
On the evening of the 2nd I counted 127, nearly as
many more must have got in unseen. I think there
must be now (at the close of the month) fully 400 or 500.
