Spangled Drongo Mimicracy

["Greg & Val Clancy" <>]

Hi Belinda,

I am always amazed at the sounds that emanate from Spangled Drongos.  I have 
also heard them mimic the calls of the Pied Butcherbird.  There is one call 
that most/all Spangled Drongos make and I am not sure whether it is an 
imitation or just coincidence that it sounds like another species' call. 
The call that I am referring to is the Brown Goshawk chatter.  When I hear a 
Spangled Drongo I sometimes immediately think 'Brown Goshawk' then when I 
hear the other rasping calls I realise that it is a drongo.  Has anyone else 
heard this call?
