So going back to my yard, earlier photos were taken while the snow was coming down.
There is still plenty out there for the birds to eat, it's just a lot of the smaller plants like Coreopsis, and most of the Coneflowers are under the snow. They'll just get eaten later on. Also the Coreopsis variety I have doesn't get very tall.
Black Eye'd Susan's are still up in abundance.
Most of the yard though is a barren waste land. Pretty but useless... unless you like snowmen.
