I have a thick hedge in the back yard. Below is a picture from the summer (aaahh, summmer) and now there's about a foot of snow on the ground. We're in a suburb of Wilkes-Barre and I put out bird seed. We don't get Redpolls, Evening Grosbeaks, or crossbills but we do get House Sparrows - hordes of them. Lately, we have about 30-40 at a time. All that chirping might attract some attention. It did.
Watched a Cooper's Hawk dive in to the hedge and emerge with a sparrow. This hedge is dense enough that it's difficult to put your hand in and pull those stupid nightshade vines out.
One down, thirty-nine to go.
