[March 17, 1911]

  Clear & cold (10 [degrees] min. 30 [degrees] max.) but with only moderate
wind, chiefly southerly. Snow thawing rapidly.
  Despite the improvement in the weather I saw and heard
only a very few birds and these all of wintering kinds. I 
listened in vain for Bluebirds and there were only two
Juncos at the seed bed. I wonder if the terrific blizzard 
of yesterday did not kill a good many birds.

Nuthatches caching small pieces of suet.
The [male] gives them to the [female] to carry off.

  The pair of Nuthatches come regularly to the suet, 
oftenest in the early morning. The [male] was digging out pieces 
up to the size of a large pea and carrying them away
to store them in crevices in the trunks & behind scales of loose 
bark. He took them to different trees & in all directions usually
going about 100 yards. Whenever the [female] was with or
near him he invariably employed her to carry off and cache 
the morsel. She took it from him without hesitation and
flew, as he did, in various directions, chiefly to apple trees 
in the orchard. Curiously enough he would not permit her
to touch the main store of supply from which he was drawing. 
Whenever she attempted to do so he attacked her quite viciously
and drove her away. Yet the next moment he would give her 
the small piece that he had just extracted.
