More fun than communal roosts is the fact that juveniles leave home about now and congregate in non-breeding flocks for the next few years. I remember being excited at seeing my first such flock somewhere in the mid-2000s, a group of 35 birds. The very few breeding pairs in our area that began breeding here just before the turn of the century finally had produced enough young that they could find each other and group up like they do in the rest of their range. Very exciting.
I still don't see these flocks of non-breeders very often. But, it's a sign the local raven population is doing well. Kevin From: [email protected] <[email protected]> On Behalf Of Marie P.

Well according to Birds of the World, Common Ravens do indeed form communal roosts. Very cool. First I've ever seen this dusk flight in this neck of the woods.

I just stepped outside to cut some herbs for dinner, when hearing the croak of a Common Raven overhead, I looked up and witnessed an astonishing sight. A steady stream of Common Ravens flying overhead, quite low, some circling as they do on thermals then proceeding, headed southeast. I counted about thirty then lost count. They were acting just like crows going to roost. Maybe the corvidophiles on the list can elucidate as what was going on? Do they actually form big roosts at this time of year? I did not know this. I am used to seeing smallish family groups or pairs. Or maybe was this a migration event ahead of some cooler weather coming in? Quite fascinating whatever the reason.
