Golden
Whistler
- Pachycephala pectoralis
Named for the male’s bright plumage
colour
and strong voice, golden whistlers are some of the most conspicuous
birds
in the Atherton rainforests, both visually and acoustically. Each male
golden whistler has a repertoire of song types, most of which end with
a loud upslurred syllable. Males sing with eventual variety; they
repeat
one song type a number of times and then switch to a different song
type.
The first nine songs in the above
sound
file come from a continuous recording from a single male. His first
three
songs are the same song type (the type pictured in figure 1), however
his
fourth song represents a second song type. The fifth through eighth
songs
are repeats of his first song type, but on the ninth song he returns to
his second song type. The last two songs in the recording come from
different
males and represent two further song types, the last of which sounds
remarkably
like the male song of the eastern whipbird.
Neighbouring golden whistlers
engage in
obvious countersinging behaviour. Males will perch in highly visible
locations
and countersing back and forth for extended periods. On several
occasions
I observed two males countersinging with the same song type. This
song-type
matching is a common feature in birds with repertoires, and is thought
to be a signal of directed aggression.
R. J. and M. N. Brown published
an intriguing
report of duet singing by a pair of golden whistlers in southwest
Australia
in 1994. They describe a male and female jointly attacking their
reflections
in the window of the Brown’s home. During the attack, both the male and
the female sang songs which appeared to be identical. Furthermore, the
male and female appeared to coordinate their songs in the form of an
overlapping
duet.
Habitat.
Golden whistlers are found in all
types
of habitat from gardens and golf courses to mangroves and rainforests.
Range.
Four races of golden whistlers
are found
throughout most of eastern and southern Australia. These recordings are
from the P. p. pectoralis race at the extreme northern end of the
golden
whistler’s distribution.
