1913.
Feb. 17
[February 17, 1913]

Parus hudsonicus.

  Clear, calm and mild. The Hudsonian Tit
heralded his approach to the suet by my window at 2.55 P.M.
by calling spee - zee, zee; spee - zee. Stayed 35 seconds.
Returning at 3 P.M. he called tchip - chip - chip - chip, tsee and
remained15 seconds.

 Feb. 22 [February 22, 1913]  Cloudy, calm and very warm, Raining all day, at times heavily.
At 11.17 A.M. The Hudsonian appeared at the suet. After
calling pse - pse - pse - pse, psee twice he feasted for 5 seconds.
At 12.45 I heard (but failed to see) him in the rhododendron thicket
just outside my window. He was now calling tswee - ee - ee - tswee -
ee - ee uttering those notes very rapidly in a rather loud voice.
They reminded me of some of those sometimes given by a
Carolina Wren. I think they must represent one of the
apparently rather numerous variations of the Hudsonian's song.

Feb. 23 [February 23, 1913]  Clear, calm, cool. At 12.40 I heard the Hudsonian
call te - te - te - te - te twice in quick succesion. The next
instant he appeared at the suet. After perching within reach
of it he remained there only 2 seconds and then departed
without as much as a single peck at it.
