Concord, Mass.
1903.
May 8
  Cloudless & hot with light N.E. breeze & intervals of dead calm.
Ther. rose to 80 degrees at noon.
  Spent entire day out of doors walking to Ball's & Davis's
Hills in A.M. & strolling about Birch Field in late P.M.
I fully expected to find a number of freshly arrived migrants
but the only species noted for the first time was the Yellow-
throated Vireo of which I heard one singing near the house.
There were plenty of Black-throated Green Warblers, Black &
White Creepers & Oven birds but these were scattered about
everywhere. In no place did I see anything like a flock
of migrants collected in one spot the nearest approach to it
being three White-throated Sparrows on Davis's Hill.
  Perhaps I should also except the Blue Jays for the woods
were literally swarming with them both yesterday & to-day
& I saw as many as four or five together in several places.
They were very noisy & active. I think they must have
been migrants just up from the South.
  Still another bird probably freshly arrived migrant &
certainly new to my list was the Whippoorwill which sang
for a minute or more this evening very near the house.
  A Thrasher was singing gloriously early this morning
directly in front of the house.
  The Phoebee's nest in the horse shed at Ball's Hill had newly
hatched young to-day.
  I examined both the stumps near the cabin in which Chickadees
reared young successfully last year but neither is occupied
by them this season although both cavities remain exactly
as they were.
  Mosquitoes were troublesome in the woods this evening
for the first time this year.
