Hello Peter,
Just to pick up on your comment that "I'm not sure where Phil's idea of 'very
different Calls' comes from". Until I'd spent some time at O'Reillys in the
rainforest I would have agreed with Phil - the calls of Northern Shrike Tits do
sound different to Eastern Shrike-tits but now that I have had more experience
I would modify that statement to ......sound different to most Eastern
Shrike-tits.
In my experience, the rainforest inhabiting birds at O'Reillys (a very odd
habitat for a Shrike-tit) do have in their repertoire calls that are almost
identical to the northern Shrike-tits at Drysdale River. I've heard and
recorded lots of Eastern Shrike-tits and haven't heard "northern" type calls
anywhere but at O'Reillys. I would be interested to know where you've heard
these calls in the east - they must surely occur elsewhere because you are
obviously familiar with them. Unfortunately we know so little about the entire
repertoire of all but a few of our native birds in Australia that it's
downright embarrassing.
For those who are interested in the different Shrike-tit calls, my website has
a good selection where they can be compared easily .
Cheers
Graeme Chapman
