Down here in my neck of the woods ( well, actually it's far from my neck of the woods ) craws like that are small bites for them big mommas, of course you yanks see them craws and go thinkin' : oh, these are beeg craws !, at Cajón de Peñas we found lotsa big mommas with "acamayas" showing from the mouth. Google acamaya so you can see how big those things are, of course, things are biggere down here in the South.
