21 – Buff-banded Rail; 22 – Purple Swamphen (the eye borrowed for the 2-eyed Lyrebirds); 23 – O-b Oriole; 24 – Olive Whistler ; 25 – Aust Spotted Crake; 26 – E Koel, male and female. 13 out of the 26 would be a good score, I think. The most difficult were 5 and 25, particularly if you had never looked a coot in the eye. 22 had a trace of the swamphen’s shield and the pink rim of the spotless showed in 16. I chose only a moderately bulgy eye for the chough. Other species can be a little bulgy when excited eg the male koel at 26. Iris colour can vary according to sex and age eg young birds often have dull brown eyes. I could have made it easier by showing more of the faces, but that would have been a different kind of thing, not appropriate for elite bird-identifiers.
