Ther [Thermometer] Saturday, Sept. 30, 1916 [September 30, 1916] Wea [Weather] Fine
aurora borealis
Brilliantly clear with raging N.W. [northwest] 
wind. Cool through day, almost frosty
by 8 P.M. when the northern sky was
ablaze with the search-light rays of 
the finest display of aurora borealis I
have ever witnessed in this latitude.
 Birch Field teeming with Yellow rumps [Yellow-rumped Warbler]
at 9 A.M. Not less than 30 of them there,
mostly in two flocks. Not nearly so
many in mid-afternoon. With them
we saw a juv. [juvenile] Chestnut sided Warbler [Chestnut-sided Warbler],
at least 4 Blackpolls [Blackpoll Warbler] & 3 or 4 D. virens [Dendroica virens]
In our dooryard or along the neighboring
lane were 4 or 5 Robins, twice as
many White-throats [White-throated Sparrow],a Phoebe, a Towhee,
a Cat-bird [Catbird] & a Swainson's Thrush. Saw
another Swainson [Swainson's Thrush] & a large typical aliciae
in Birch Field. In Cedar Park found where
a Hawk had devoured one of my white
Homer Pigeons leaving only a pile of its
feathers & the upper part of skull minus the
eyes but with part of cervical vertabrae [vertebrae]
attached.  A lesser pile of feathers masked 
which bird had apparently first been brought
down under apple tree near Peach Orchard.
  Spent most of day superintending work of
men in front of house. Henry golfing at 
Bensens in A.M. He & I visited Birch Field twice
Mr. & Mrs. A. C. Robbins thier [their] sons & Norton called

Glorious.
Heavy flight of Yellow rumps [Yellow-rumped Warbler]
  Brilliantly clear with strong N.W.[northwest] wind
which abated gradually thro.[through] day & ceased
wholly at nightfall. Air crisp & very cool.
  Warblers migrating overhead in considerable
numbers at 10 P.M last night.  Birch Field
swarming with them this forenoon, mostly all
were Yellow-rumps [Yellow-rumped Warbler]. Among them, however, I saw
a [female] Black-throated Blue [Black-throated Blue Warbler] & one Black-poll [Blackpoll Warbler].
With or near them saw a Ruby-Crown Kinglet [Ruby-crowned Kinglet],
2 Gold-Crests [Golden-crowned Kinglets], Chickadees, a Nuthatch of both
kinds [White-breasted Nuthatch] [Canada Nuthatch], a [male] Downy [Downy Woodpecker], a Hermit Thrush, a 
dozen or more Juncos. Henry saw an adult
[male] Sharp-shinned Hawk gliding low through
birch covert. A [female] Red-wing Blackbird [Red-winged Blackbird]
flew low over us there, showing her striped
underparts distinctly. Comparatively few
Jays now. They have decreased steadily of late.
In Farm came 6+ Robins, 12 Cat birds [Catbird], a Gray-cheeked Thrush,
12+ White-throats [White-throated Sparrow], a [female] juv. [juvenile] Sapsucker tapping
softly on trunk of elm. A Phoebe by barn
cellar, a Song Sparrow in front of house.
  Henry & I took our last walk together to
Birch Field in mid-forenoon. He left me just
after dinner & motored to Auburndale to take
Federal [?] for W. [Washington] to-night [tonight]. I went after
to Birch Field with Timmy [Brewster's dog] at sunset.
