Concord, Mass.
1905.
May 15
  Cloudy with light showers. Wind N.E. in P.M. Rather warm.  
  The country was better supplied with birds today than 
on any previous date this month but they were very
generously distributed as is usually the case when the
weather is calm & cloudy. At Ball's Hill there were
several Yellow rumps, a Magnolia Warbler, a Canadian Warbler
& a Wilson's Black-cap. At the farm in the apple
orchard, where the blossoms had already begun to cover
the ground with their fallen petals (especially after the rain
began falling) I found a considerable number & variety of
Warblers. There were two Nashvilles, a Golden-wing, two
Usnea Warblers, a Black-poll, a Black-throated Green,
a Blackburnian, two male Black & Yellows, two Canadian Warblers,
and a Wilson's Black-cap besides the resident Yellow
Warblers & Redstart. All these birds spent much of this 
time searching for insects among the snowy clusters of
apple blossoms, also flying to the oaks in the neighboring 
woods at intervals. 
  Yesterday I saw a Chickadee near the farm house with
a big tuft of wool in its beak. Today I followed it to
its nest which is in a hole in the under side of a 
dead prong of an elm directly over the door yard and 
fully 50 feet above the ground. I saw the bird enter
the hole with a piece of wool & emerge without it. I
have never before known a Chickadee to nest so high.
The male bird has been whistling much of late. The hole is near
the end of the prong & is a round, pecked hole.
  The Bats in the shed increase in numbers. There were ten
yesterday and fourteen today (See entry under May 12)
Bats.
