Edwin:
Not to get technical, but I assume you are asking if the different
races have different songs. I would like to know of any studies on the
song of pardalotes, especially the existence of regional dialects (not
dependent on being a separate race). Although I can't answer your
question with a definitive reply, I can mention that pardalotes are
songbirds and many songbirds learn to sing their species-specific songs
early in their lives (within limits). I have noticed that the songs of
different individual pardalotes seem to vary in cadence and pitch.
However, I haven't qualified the difference and I am not sure if how much
the levels of motivation, etc. can effect these parameters. Until
informed otherwise, however, I would bet that there are regional dialects
within races not to mentioned across races. If so, this begs the question:
how sedentary are pardalotes?
Cheers, Jim
