  As I was walking down lower Sparks Street I heard
somewhere in Hubbard Park & repeated several times the
wild, ringing notes of a Solitary Vireo. After a short
interval of silence the song of a Yellow-throated Vireo came
from apparently the same spot. I have little or no
doubt that the bird was the Solitary Vireo which was
in and about our garden in April singing, alternately,
the songs of its own & the Yellow-throated species.
Richard Eustis whom I met told me that a Solitary Vireo
had been seen several times lately in Hubbard Park. I
wonder if it is possible that he is breeding there.
  C. tells me that the Robin roost in the Garden has
been growing rapidly of late. She counted ninety one
birds coming in on the evening of May 17th and thinks
there were considerably one hundred in all. They
"made a perfect babel of noise", she says, numbers of
them singing at once. The poor Cat-bird seems greatly
annoyed at their presence spending most of his time
in the back part of the garden. Last year she
nested twice in the thicket where the Robins afterwards
roosted & one roosting this spring.
