Song (?) of Blue Jay. Fine
Brilliantly clear, very windy (N.W. [northwest])
rather cool; altogether typical March
weather.
  In Garden: a gray Purple Finch
eating seeds of Parkman apples;
2 Jays, one of them uttering a
variety of subdued & very musical
notes some delightfully liquid in
quality, keeping it up ceaselessly
for several minutes. I heard this
through my closed Museum window
to which the bird must have been
very near & on the roof or gutter
just above, I thought. Is not this
the song of the Blue Jay?
  Spent day in Museum working
on Alder Flycatcher story. Composed 
a page of introductory general
matter & compiled considerably
more than that from field notes.
  Nuttall Club. I attended meeting
of Council only being too weak
to stay on for the general meeting.

Ther [Thermometer] Tuesday, Mar. 16, 1915 [March 16, 1915] Wea [Weather]
Fine
Brilliantly clear, almost windless, 
seasonably warm - or cool.
  Hundreds of snow drops, very many
squills and about a dozen yellow
crocuses in full bloom front of
Museum. House bulbs almost
done flowering. They have been
uncommonly fine this year.
  Garden birds: - A solitary Purple
Finch (gray) in Parkman's apple;
two Jays, one singing softly again
close to my study window;
House Sparrow to the number of
ten or a dozen.
  Worked all day in Museum
despite rather distressing nervous
exhaustion which seems to increase
daily although otherwise the aftermath
of the "grippy" attack is passing off.
Wrote five pages for Alder Flycatcher
story, compiling from journal notes. 
The last of Tyrannidae now dealt with.
Victrola music this evening.
