Snow Storm
Mild weather again but damp
snow falling ceaselessly all day 
loading every branch and twig and covering the ground to a depth of about 3 inches. Little or no wind.
Hudsonian Tit and white-throat Sparrow
heard (but not seen) close to the suet that hangs by my window. 
  Of late I have been frequently 
disturbed by rather loud but intermittent
tapping on the Museum roof over my 
desk. Hitherto I have attributed it
to a Woodpecker but today Gilbert [Robert Alexander Gilbert]
saw 2 Blue Jays making it by
pecking at the copper gutter.
  Worked all day on Black bellied
[Black-bellied plover] and Golden Plover stories, rewriting most
of former and adding 2 fresh pp. [2 fresh pages] to latter.
Nuttall Club evening. [?] on 
"Common Tern."

Ther [Thermometer] TUES. FEB. 4, 1913 [Tuesday, February 4, 1913] Wea [Weather]
Sparrow-hawk [Sparrowhawk] in Garden.  Fine
  Clear & mild. Wonderful snow
foliage at sunrise, partly dissipated
about 8.30 by rising wind which
tore much of it from the trees, altho
some still clings to them in sheltered nooks. 
  In the Garden saw a [female] Downy [Downy woodpecker] in 
catalpa and 3 Crows on wing. Heard a 
chickadee & the white thr. Sparrow [white-throated sparrow]. 
  As I sat at my desk about 3 P.M.
the cry of a Sparrowhawk came 
faintly to my ears. Stepping out I 
saw the bird, a [male] fly from near
the top of our Gravenstein apple tree 
bearing in his talons booty that looked
like a Sparrow. He went off over our
house towards the river. 
  Began Ring Neck Plover story this 
morning and worked at it all day
without accomplishing anything at all. 
My brain simply refused to work
perhaps because it has been overworked
of late, perhaps because I have not
smoked to day.
