Stalked the source of an incessant pipping noise, and found this cutie up high. We only have four Cuckoos to choose from here (North Tas), Pallid, Fan-tailed, Horsfield's Bronze & Shining Bronze.
He was twice the height of an average adult Fairy-wren at least, so I guess the two Bronze-Cuckoos are out? My first thought with the non-stop begging (how their squawk-box doesn't break, I'll never know ), and barring on the tail, made me think Fan-tailed perhaps?
Interestingly, he was being fed by a pair of Thornbills, then shortly after, a small family of Fairy-wrens took over the feeding for quite a while. I have read that Pallid fledglings are so good at begging, that parents (other than their hosts) will quite often temporarily leave their own young to give the cuckoo chick a quick bite to eat - I guess this could apply to any Cuckoo young perhaps. Was very interesting to watch anyway.
Would love some help confirming ID please!
Looking at the Brown on the wings, and a lack of yellow eye ring, my thinking is Fan-Tailed, but as always, happy to be proven wrong. The Pallid should have more wing markings.

This is a tricky one... if it was a Fan-tailed, the bright eye-ring should still be evident in a juvenile bird. Do you mind if I send a copy to some expert people that I happen to know?

Thanks Dale! Has had me stumped
.
Not at all Brandon, that would be brilliant if you could, thanks! Here are two more shots, out of focus
but they may help further with ID & size comparison etc.

... And the results are in! It has apparently been decided that it is a Fan-tailed Cuckoo. YAY!!!

And the winner is....
Fantastic, thanks Brandon - and thanks Brandon's expert people too!
