Normally I see lots of ravens congregating right outside my office window (no doubt drawn by all the bones I set out there), but just now a giant pterodactyl-looking thing with a huge wingspan landed right in a tree in our yard.  It looked like a buzzard.  All the ravens were pestering it, and finally it took off across the field, with them in pursuit.  My phone cam couldn’t quite capture a good closeup, but here’s a silhouette, with ravens for size comparison.
