We’ve long had ravens at my school however crows are making more and more of an appearance here, too. Oddly, when crows show up, ravens usually leave. I suspect it’s the abundance of food available here — kids are notoriously messy. But, the Ravens and Crows seem to be working out a timeshare system where they use the playground at different times. This flock (murder) of crows was on the playground (16 strong) until my camera appeared and then they all flew frantically off to these distant trees. Sorry about the blur on this picture it’s zoomed in and super-cropped.
I love corvids. The crows at our school are more skittish than the ravens who are brazen and will come look in our windows and land right on the railing outside my classroom and kronk at me. They are heading for the garbage cans where the reach in with their beaks, pull up the plastic liner, hold it with a foot, and reach in again and again until they lift the food at the bottom to where they can reach it. Tricksy critters, ravens.
And crows.

A flock of crows is called a murder? I love it!! And I love that they are timesharing with the ravens. I have a huge murder of crows that hangs around my apartment.
Yes, a group of crows is a murder while a group of ravens is an unkindness. I love words!
Unkindness! Cool, I wonder why these two groups of birds obtained such words to describe themselves.
