an Empidonax minimus, a Sayornis phoebe singing, and
a number of Petrochelidon lunifrons. At evening I saw
a Bittern and a Green Heron and heard a Cow bird &
some Bank Swallows. These additions carry the list
up to 39 species.
Eave Swallows
  The Eave Swallows were at Parker's nesting under
the eaves of the barn. Parker put up a chest to
support the nests this spring but in spite of it
a number of nests full of young fell during the
thunder shower of last evening I was told. Parker's
son says there were 17 complete & occupied nests
yesterday. This morning there were only four or five
perfect ones but I counted a dozen in which the
birds were sitting although some of them were little 
more than narrow, semi-circular platforms from
which the young or eggs had apparently fallen.
