and distinctly separated from each other in time. This buzz(and
the buzz-pop)is made with spread and quivering wings while the young-
while
ster is running toward me, low to the ground and circling about my
occasionally
feet pecking at them impatiently as if wanting some kind of action
on my part. Off-hand one would say that it is clearly a call for
food. Perhaps it is sometimes; certainly it is not always. I think
it seldom is, and that it is really a demand for attention, for if
the bird then flies up to my shoulder as it frequently does, the
buzz ceases instantly and is followed by little animal sounds
perhaps expressive of affection or contentment. Or if I reach
down and pick it up bodily it may subsideat once with the same gentle
sounds or, in marked contrast, snarl nastily like a cat, struggle
to get free and either run off or else jump up on me and settle down
contentedly immediately notwithstanding the explosion of temperament
at the instant it was caught. (It makes this same angry snarl when
stepped on by its brother--or sister?). This snarl may be described
as a disagreeable, nasal raowh or waowh, the a being short. On
hearing it, the cause of it might reasonably expect to have a fight
on his hands, yet in three seconds or less the bird may be sitting
on his shoulder placidly preening.
When flying up to a perch these birds are silent; yet when
alighting on a human being they always announce their coming and
arrival vocally by pleasant sounds. In other words: the inanimate
object is not class ed as something to be communicated with, but
these
the human friend is. It appears to me,then, that the sounds are
perhaps nothing specific and
intended to convey some message, perhaps not consciously, but at
least they indicate some recognition on the part of the bird of a
friendly fellow creature possessing some measure of understanding
and capable of responsive action. (I suppose this point of view
represents naive anthropomorphism and that all this is readily
explained by a simple, elementary pattern which the bird is constrain
