Relative? The hoatzin is not a galliform. (And probably not a cuculiform
either.) Not that anyone would know _what_ it is... turacos (Musophagidae)
and pigeons (Columbiformes) have recently been suggested and have quite some
support from the data.

While I don't have your experience, I've seen lots of (fried) chicken and
turkey alulae with small, certainly functionless, usually straight claws. By
far most specimens have these claws. I think I've once seen a claw on a 2nd
These are definitely not metacarpal spurs like seen in anhimids.
