This is what a lyrebird looks and sounds like. If you prefer to see the same clip with lower picture quality, but in David Attenborough's well modulated tones, see the clip at the bottom.
I forgot to mention it yesterday, but just before we got to
Tahune, a Superb Lyrebird crossed the road in front of us – a rare sight as
they are normally very shy. The remarkable thing about the Lyrebird is its ability
to mimic other sounds. I was telling Miss Ten that the last one I saw - also in
this area, on my first walk to Adamson’s Falls, sounded like a chainsaw and she
said, “Is that why they call them Liar birds?” You'll see why they call them Lyre
birds when you have looked at one of the clips. For information about their habits, feeding and breeding click here.
Lyrebirds are not native to Tasmania but were initially introduced
from the mainland by Lady Franklin in the 1800’s. In the 1930’s and 40’s
fearing mainland extinction due to habitat loss and the presence of European predators such as
foxes, several more were released near Hastings- just south of
here, and Mount Field. Beautiful as they
are, as with most introductions e.g. rabbits, cane toads and blackberries, there is a
downside.
At first Lyrebirds seemed to have fitted in rather well, possibly
occupying the niche which used to be occupied by the small Tasmanian emu which
became extinct soon after white
settlement (No, the settlers didn’t
necessarily hunt them to death. It is now thought that the rats which came with
them, may have eaten the eggs), but now the 22 birds which were introduced by1949 have grown to an estimated 8000 birds and have extended their range all
over the state. Their habit of scratching up huge mounds for nests now
threatens other species - tearing out seedlings, removing the insects and preventing
regeneration. It is in the leaf litter
and moss that the seeds for our rare species germinate and once loosened, they
are easily washed away. This is why some
of our beautiful wilderness waterfalls will be very slow to recover after
recent floods.
Because of their history on the mainland, Lyrebirds are
still protected, but the day may come when Tasmania may have to consider
culling them. This is the problem when you live on a small rock which is in
fact a floating Ark. It is also why we
have to be s -o -o -o -o careful with what can be brought in, so please don’t complain
when we ask you to ditch you fruit and vegetables on entry. Every introduction,
even a microscopic one, poses new risks.
Enjoy our lyrebirds while you can.
UPDATE 3/8/2019 :Just came across this interesting bit about Lyrebirds, which debunks the myth that the chainsaw sounds I heard the lyrebird make are copied from human activity. If you hear something like that record it with your phone and send it to Send it to offtrack@abc.net.au
