Corvids are some of my favorite animals. When I became a Virginia Master Naturalist, I did my final project on intelligence in crows. I see ravens less frequently than crows, so I’m even more excited when I come across them. Unless you can get a good perspective of their size – ravens are much larger than crows, the size of a red-tailed hawk – it can be hard to tell the difference between a crow and a raven. I used the this page on Cornell’s excellent bird site to verify these were ravens: I used the “4 fingers” tip.
At the wildlife hospitals I’m training at, I am frequently told of all the ways the crows, ravens, and jays may try to trick me. I’m really looking forward to working more with these incredibly intelligent species, in fact, crows and ravens are two of the animals I would like to rehab at my own home some day.
