|Cleared for landing!|
This particular unkindness of ravens (which is an unfitting name for ravens, in my opinion) was quite happy to have discovered one such garbage can.
Sometimes the Black-billed Magpies will join the ravens in their garbage-gutting, or will visit afterwards to pick over the scraps. Here's one Black-billed Magpie landing trace.
The one trace for which I've been searching for over a decade is a predatory avian trace. This would be the impression left by a bird, such as an owl, hawk, or corvid, attempting to catch a small mammal. Our predatory birds are still active hunters in the areas in which they winter, so if you have a wooded area, park, or cemetery* nearby, check out the ground for landing strikes by hungry birds. I may have two such traces I can show you in my next post in the Tracking the Wild in Your Neighborhood series. Stay tuned!
*Yes, cemeteries. Cemeteries are quiet areas, often near or within wooded sections. Cemeteries can sometimes be the few remotely "wild" areas in a densely populated area. They also have the benefit of not being subject to the regular foot and vehicle traffic of a city. Cemeteries can be calm oases for urban wildlife.
