We have one of those bird feeders that sit right in the window and has a one way mirror so you can see the birds but they can't see you. This is where the cat spends 80% of the day. Every now and then you hear a thump as she crashes into the window trying to get one of the birds. It's not a great picture but if you look closely there is a bird sitting in the feeder. Now that everything is covered with ice there is a constant flow of birds to the feeder. (as you can see I need to fill it up again!) It's really kinda fun to watch them. Just ask Misty!
