Lawrie, is your estimate of <10 birds from 32 records based on a formal
estimation technique? I would have thought that if there had been 32 birds
detected by birders, then there should be many more that weren't detected, so I
would say I didn't have a clue how many there were.

Whilst there were 32 records to date this year in Victoria, that's most
unlikely to be 32 birds. They are moving around a bit in central
Victoria/Melbourne, and apparently are seldom encountered in the same place on
consecutive days. There are probably <10 individuals. Until the number gets
higher, successful breeding may either not occur, or be difficult to detect.
