  A Golden crested Kinglet was singing this forenoon
in the woods behind Ball's Hill. I wrote down (on 
the spot) the following rendering of its song: Tsee-tsee-
tsee-tsee-tril-il-il-il-il-il. The tsee notes were 
were thin, wiry and high-pitched and very similar
to the ordinary call notes of the species but with
less of the z sound than the latter. The trill il etc.
notes were pitched much lower there than tsees and
were rather liquid and, indeed, not unmusical in
quality. All the notes composing the song were
delivered hurriedly and in rather feeble tones.

  Soon after this I saw the bird and its
mate (or at least a female of the same species)
among some alders, near the ground. What charmingly
dainty and sylph-like little creatures! One can
never cease from admiring them and wondering at
their grace and animation of movement especially
when, as happened repeatedly to-day, they are
seen poised on fluttering wings, like Hummingbirds,
inspecting the terminal leaves or buds of some
slender spray.
