June 1
to
July 6
  Vireo flavifrons - This species appeared to be wholly
absent from the Brattle Street Region in May and early
June but on the 18th of the latter month I heard a 
male in full song in our lindens. This bird remained
about the place during the remainder of June and the 
first week of July singing freely at all hours. I did not
once see it accompanied by a mate and am inclined
to believe that it did not have one.
  Vireo gilvus - A Warbling Vireo spent this season in
Hubbard Park occasionally straying into our grounds.
On June 21 I heard young calling in the trees at
Mercer Circle so I infer that a brood was raised
there.
  Spinus tristis - I heard the call notes of a Goldfinch
in our garden on June 20 and 29. On the 30th and
daily after that a male was almost constantly flying and
hovering over the garden and jungle singing loudly and
delightfully. From his behavior I have no doubt that he
was established for the season & preparing to breed. On several
occasions I saw a female with him.
  Spizella socialis - A pair of Chippies frequented the
garden and lawn through May and June. Towards the close 
of the latter month I saw one or two young birds
following them about.
  Passerina cyanea - On June 2 I heard an Indigo Bird
singing in the garden. As it did not reappear there
I concluded it must have been a belated migrant.
