Ther [Thermometer] Tuesday, Jan. 18, 1916 [January 18, 1916] Wea [Weather]
10 [degrees], 22 [degrees] Fine.
Clear, cold; light variable winds.
Typical mid-winter day of the sterner sort.
   In Garden: a Chickadee calling close to
my study window, a dull-colored
Peabody bird in clothes yard, with
House Sparrows; afterwards either the
same or a similar looking bird
scratching among fallen leaves in Jungle. 
  Gray Squirrels out again despite
the cold. I saw one or more
repeatedly running singly over the
snow.
  Spent day in Museum. Worked
on the bird collection in A.M.
examining and rearranging specimens
in four cans recently bisulphided
and throwing out skins badly 
injured by [anthrinae?] of which they 
were only 3 or 4. Found about
that number of dead "bugs".
 Wrote letters in P.M. Victrola
music this evening.

Ther [Thermometer] Wednesday, Jan. 19, 1916 [January 19, 1916] Wea [Weather]
10 [degrees], 22 [degrees] Fine.
Clear & cold with light N.W. [northwest] wind.
  In Garden: Woodpecker gathering at
9.30 - 10 A.M. consisting of [male] Hairy [Hairy Woodpeckers] and 
[male] and [female] Downies [Downy Woodpeckers] together for almost half hour
in apple tree by lilacs and a [male] flicker
in Parkman's apple [tree] eating its fruit.
The black & white spotted birds worked
energetically & ceaselessly on what
appeared to be perfectly sound apple tree
trunks & branches hammering away at
them most vigorously but although
watching them long & closely through my
glass I failed to see that they got
anything in the way of food. 
  A Blue Jay on ground, a Crow on
wing & a score or so of House Sparrows
complete the list for to-day.
  Spent day in Museum working on
uncatalogued nests, eggs & skins labeling
some & putting many in new boxes.
Batchelder & Bangs came up for the
afternoon to look for Newfoundland birds
in my collection.
