The cold weather that's coming must be pushing birds, because yesterday and today our house has been surrounded by Robins. I would guess that there are at least 100 of them here by the house, and possibly more.

It's usually Blue-Jays, Chickadees, Nuthatches, Mourning Doves, Woodpeckers, etc. I've hardly seen any of them, since the Robins arrived.

Edit - Double that, within sight of the house.
