But it's a bird and more primitive than Opisthocomus ;-)

In fact I think Cairina also has a claw on the 2nd finger but I can't repeat 
the observation because that species is extinct in my backyard. On the 
repeated observations issue (and not only for David): I've been repeating 
those observation for 8 years. 
And it's good to know that this feature is not endemic.

Caught a few young chickens this weekend, about 3 weeks old, confirmed beyond 
doubt: curved claws on a somewhat stiff facsimile of a finger.
