A few more turkey points of interest. If you can add extra info on any
of these points I'd be interested: I'm doing this without the literature.
I've yet to read about this, but turkeys in captivity (at least) use their
primaries in a strange acoustic display: they scrape the feathers along
the ground making a loud shhh-shhh-shhh noise. Those that are kept on
concrete wear down the tips of their feathers so that the distalmost end
of the feather is horizontal and parallel to the ground, not pointed as in
an undamaged feather. Female turkeys prefer the males with the
broadest skulls, though I'm sure vocal prowess, size and condition
must come into it.
Displaying male turkeys blush, turning from pinkish-red to deep red
with blue and violet. As they become darker in colour, the wattle that
hangs from the cere is distended and dangles down below the beak. I
don't know if other wattle-bearing birds also distend their wattles
during display.. keep this in mind if you give your hadrosaurs or
Turkeys are (so the books say) named because they were originally
confused with guinea fowl and were thought to originate from Turkey.
Surely it must be more complex than that. While turkeys were
obviously not discovered until Europeans settled the New World, there
is supposed to be a bird that looks just like a turkey (which of the two
species I'm not sure) in the Bayeaux Tapestry. I seem to remember
there are feral turkeys in the UK somewhere... (the group is not
included in Heinzel et al. though, so this hasn't been confirmed).
