She moved higher into the tree and settled herself comfortably about
ten feet above the ground as if she were going to stay there indefinitely.
I went away, returning at 6:15, to find her still sitting there quietly.
This may have been her resting place for the night. During a part of
this time Greenie was scrapping a few trees away. There was no exchange
of calls and Greenie did not appear in the open. Soon the sound
stopped, suggesting that he may have been selecting a roosting place and

birds have for foot-travel over flight even for considerable distances
and also their recognition of my call. Incidentally Greenie's course
was in the middle of the street; Brownie's mostly near the shrubbery.
While Brownie was on her way, a hawk crossed her path carrying some small
object in its claws. I suppose each was aware of the other's presence,
but there was no evidence of it, unless it was the thrasher's selection
of route.
During the rest of the day both adults were seen frequently,
