Hi
as I mentioned before I have just spend 3 months bushwalking in Kimberley
and I noticed the following "pairs" of birds didn't overlap.
Pied butcherbird and silver backed form of grey
black faced cuckoo shrike and little cuckoo shrike
striated pardalote and red browed pardalote.
I know that evolutionary theory states that every animal has its own
environmental niche but I did expect these to be dividing up the habitat in
some way rather than being absent when the other one was present. In fact,
I only saw red browed pardalote on one occassion but it was most strking for
the other species.
The other thing that struck me was how rare the northern rosella was. In
all that time I only saw the bird on 6 or seven occassions.
Also saw one budgeriagar one and a half hours boat ride from Wyndham up into
hte Durack river-unexpected sighting. I guess it could be called
sub-coastal northern australia but it was pretty close to the coast. My
wife suggested possibly an aviary escapee but it was wild coloured
bird-only one, was a bit unusual.
