birding-aus
G'day Andrew and B'ausers,
Over the years I have seen young Spangled Drongos showing the odd-tail
characteristics that you describe on a number of occasions, they frequently
remind of illustrations of the Ratchet-tailed Treepie of Indo-china (which I
have yet to see!)
Also every year (around the same period) I hear a call which I am sure is new to
me only to realise that it emanates from a young Drongo, hopefully in the future
I'll remember it first-time!
