Ever see a shore bird run? They don't hop, as most birds do. They
have one heck of a stride, and they're pretty quick as well. That
requires a different bone and muscle structure. I'm no expert on
avian anatomy, heck, I hardly have any actual knowledge of bone
structure, but from observing them, it would seem that the hip socket
is set up different.
I'll try to dig something up (no pun intended), but can someone with
more knowledge shed more light on the differing anatomy of birds?
