First Dragon Flies
Ther [Thermometer] FRI. MAY 30, 1913 [Friday, May 30, 1913] Wea [Weather]
Mourning Warbler.   Fine
Brilliantly clear & just pleasantly 
cool with high W. [west] wind.
  Spent day at Ball's Hill with
Duren, George & Tom, spraying trees
behind the hill chiefly. Heard a
Canadian Warbler in the swamp.
A Wood Pewee on the hill. No
north bound migrants there but
when I got back to Farm at 5
heard a Night hawk in elm by barn.
At 7 P.M. heard a Mourning Warbler
in swampy thicket on north side of
pond in Berry Pasture. During
next 20 minutes it sang almost
incessantly, sometimes one song following
another almost without pause. It
also uttered a sharp metallic cheep
exactly like that of O. [Oporornis] agilis. It
kept low down in leafy shrubbery
& seemed rather shy. I saw it
twice but not distinctly. 2 Cat birds [Catbirds]
singing near house & 2 in Berry Pas. [Berry Pasture]
[margin] Dragon Flies [Dragonflies] out in swarms all about Ball's Hill. [/margin]

Deer at Farm       Fine
Sunny with fresh N.W. [northwest] wind &
drifting clouds. Pleasantly cool.
2 Black polls [Blackpolls] singing near house in
early morning. Thought, but could not
make sure, that I heard an Alder
Flycatcher in Berry Pasture at 6.30 A.M.
& a Yellow bellied [Yellow-bellied Flycatcher] near Pulpit Rock later.
  Spent entire day spraying with
Duren. We began on Pine Hill
near wood shed & put out 3 bbls. [3 barrels]
water there. Began in Pulpit R. [Pulpit Rock]
woods & Birch Field at 10 & worked
there rest of day. Birds singing
freely and delightfully all day.
There are as many as ever of
most summer resident kinds except
at Ball's Hill. We have now 3
male Phoebees [Phoebes] at Farm. Gilbert [Robert Alexander Gilbert] saw
a Deer - a big Doe - walk across field
front of house at 7 P.M.
