I was called out by a Sydney friend a few weeks ago to a bird which had not
long left the nest and which was being fed by a Red Wattlebird. He thought
it was a Long Tailed Cuckoo (which got me moving fairly quickly) and some of
the  markings looked a lot more like a juvenile LTC than any of the
available field guides show for a young  Common Koel.
