1906.
July 16
(No 2)  
the following two evenings. To-night not one alighted in
the lilacs but about 7.30 I saw several birds fly over
the house from the garden. Soon after this Mrs. Brewster,
who was in one of the front chambers, called to me
that the Robins were assembling in our lindens. I
at once went into my study & during the next ten 
minutes saw twenty or more birds come into these trees,
chiefly into those on the western side of the front
walk. Judging by the agitation of the foliage by
the entering of the birds there must have been at 
least thirty or forty Robins assembled when the flight
came to an end. I watched the trees until all sound
and movement ceased and was satisfied that the
Robins had really gone to sleep there. Most of them
chose the lower branches that stretch out over the lawn.
This is the first time I have ever known Robins
to assemble in these lindens to roost but during former
years scattered birds have occasionally taken refuge there
after dark when something has occurred to disturb
them in the lilacs.
