Unfortunately, being caught with raven bits in the US is illegal I'm afraid, as is American crow (Corvus brachyrhynchos). I'm not sure about the Eurasian raven, though. I do know that carrion crow (corvus corax) bits are legal, and I have more than a few crow feet. I only have one matched pair however, huge feet, which I already promised to a friend. But if you're interested in anything crow, let me know!
