1902.
May 11
  Brilliantly clear with light N.W. wind. Cool
at morning and evening, pleasantly warm through the
middle of the day.
  Birds are coming by later this month without much
regard to weather.
Arrivals
It is true that there were no arrivals
yesterday but although the recent cold wave can scarcely
be said to have passed before this forenoon a number
of new birds appeared to-day. The list is as follows: -
Golden-winged Warbler, one singing at E. end of Ball's Hill
early this morning, another in the apple orchard at the farm
at about 10 A.M.  Black & Yellow Warbler, a beautiful mob flitting about in
gray birches in the cedar hollow near the Barrett Spring at 5 P.M.
Black-throated Blue Warbler, a male among some dense young
white pines in the Barrett woods (on the eastern side of the
cow pasture) at 4 P.M.
 Red-eyed Vireo, a male in full song on Ball's Hill (west end)
at 12 M.
  Yellow-winged Sparrow, one in full song at 4.15 P.M. in
the mowing field on the Lawrence farm just north of the
boundary wall of the Barrett farm (very near my hen house)
I have never known one to occur in this field before.
  Humming bird, one darting away from a bird cherry
tree in bloom in front of the barn at the farm. It
looked like a female but I could not certainly distinguish
the sex.
  The Tanagers, Grosbeaks, Chestnut-sided Warblers, Oven Birds,
& Black & white Creepers have perceptably increased in numbers
since yesterday. Yellow rumped Warblers & White-throated
Sparrows have not changed in numbers for several days.
