Concerning Spangled Drongo mimicry I have often heard them mimic a Pied
Butcherbird but I have also heard them doing a call which is very similar to
a Brown Goshawk call. I wonder if it is one of its own calls, as I have
heard it uttered by many Drongos, or whether it is imitating the Brown
Goshawk. I have also seen Drongos actively chasing off Brown Goshawks a
number of times.

Thinking about yesterday's post from Kirri Hardy on a Pied Butcherbird
mimicking a Spangled Drongo...
I have a bush block adjacent to a birders' haunt well known to
Victorians—Rise and Shine Bush Reserve. My neighbour's block is a Noisy
Miner hangout (with the consequent reduction in bird species diversity) and
every time I hear a Noisy Miner call at my place I have a fleeting panic
that I am about to be invaded and colonised by these gangsters. But, more
often than not when I hear a Noisy Miner call and track it down I find a
Grey Shrike-thrush has mimicked the call. Phew!
