Parus hudsonicus

  Clear and cold. Although at my desk all day I saw
nothing of the Hudsonian Tit until 3.40 P.M. when he appeared
among the shrubbery in front of the museum and presently
descended almost if not quite to the ground among the crowded
stems of a syringa bush in which a Black-cap Chickadee [Black-capped Chickadee]
was then flitting higher up. The two birds became separated
a moment later when the Hudsonian flew off westward. Less
than two minutes after this I saw him on the suet where
he remained only about 10 seconds, going, as he had come, in
perfect silence or at least without sound that reached my ears,
something which has not happened here before to my knowledge.
Walter Dean had come down especially to see him but failed
to do so, being unable to catch sight of him in front of
the museum and a moment too late in joining me in the
study when the bird was at the suet.

Feb. 10 [February 10, 1913]  Brilliantly clear and intensely cold but windless. For the
second time this winter the Hudsonian paid a silent visit to
the suet - at 1.45 P.M. At 3.45 he came again and was
seen by Smith O. Dexter, who happened to be calling on me.
On this second occasion the bird called tse-tse-dee
several times just before and after his stay at the suet
which lasted only 12 or 15 seconds. The first visit was
similarly brief. I was at my desk all day except between
1 and 1.40 p.m.

Feb. 12 [February 12, 1913]  Clear and cold with light wind. The Hudsonian was
noted only once today - at 10.40 A.M., when he appeared
at the tree and remained there only 15 seconds, twice
calling pse-pse-phe-psee without special emphasis on
any of those notes. They were thin and somewhat wiry in quality
