Maybe this is a real “duh” moment for me, but the first time I picked up a bird bone (and a rather large one at that), I was genuinely freaked out by how light their bones are! Thinking back, of course, it seems a bit obvious why bird that fly would need relatively lighter bones, but in my defence, it is very unsettling to have a bone be so light when you’re not expecting it.
One of the skills you learn going into zooarchaeology is quickly finding indicators that allow for relatively quick identifications off-hand. Of course I’m not gonna hand in a bone report made up of five second IDs, but when you’re faced with a pile of hundreds of animal bones, it does help to do a little preliminary analysis using a few indicators you know.
Anyway, here’s two general bone elements that may be helpful to know off hand for a quick ID of a bird skeleton:
The bird ulna is part of the “forearm” and I find that they can often be ID’ed by these bumps that are found running along the bone.
The clavicles of a bird are fused together into an element known as the “furcula“. This is also what is often referred to as a wishbone. Given this is a unique element in birds (and some dinosaurs apparently! I don’t know much about dinosaurs and their skeletons, but I can at least identify the furcula if present – it’s a bit impressive to kids, at least), the presence of this bone should be a giveaway that you’ve got a bird on your hands.
This isn’t an extensive bird identification manual (although hey, maybe that’s a post for another day?), but again, I find that having these small little hints tucked away are handy for getting a start on IDing bones. Look for more of these kinds of posts in the future!
