So much for its fine feathers; now for the manner of their use. “He
always commences his display,” writes Sir William Ingram, “by giving
forth several short notes and squeaks, sometimes resembling the call
of a quail, sometimes the whine of a pet dog. Next he spreads out
his wings, occasionally quite hiding his head; at times, stretched
upright, he flaps them, as if he intended to take flight, and then,
with a sudden movement, gives himself a half turn, so that he faces the
spectators, puffing out his silky-white lower feathers; now he bursts
into his beautiful melodious warbling song, so enchanting to hear but
so difficult to describe. Some weeks ago I was crossing a meadow and
heard the song of a skylark high up in the heavens, and I exclaimed at
once: ‘That is the love-chant of my King-bird.’ He sings a low bubbling
note, displaying all the while his beautiful fan-like side-plumes,
which he opens and closes in time with the variations of his song.
These fan-plumes can only be expanded when his wings are closed, and
during this part of the display he closes his wings and spreads out
his short tail, pressing it close over his back, so as to throw the
long tail-wires over his head, while he gently swings his body from
side to side. The spiral tips of the wires look like small balls of
burnished green metal, and the swaying movement gives them the effect
of being slowly tossed from one side to the other, so that I have
named this part of the display the ‘Juggling.’ The swaying of the body
seems to keep time with the song, and at intervals, with a swallowing
movement of his throat, the bird raises and lowers his head. Then comes
the finale, which lasts only a few seconds. He suddenly turns right
round and shows his back, the white fluffy feathers under the tail
bristling in his excitement; he bends down on the perch in the attitude
of a fighting cock, his widely-opened bill showing distinctly the
extraordinary light apple-green colour of the inside of the mouth, and
sings the same gurgling notes without once closing his bill, and with a
slow dying-away movement of his tail and body. A single drawn-out note
is then uttered, the tail and wires are lowered, and the dance and song
are over.
