Windex! :)
We had a foot of snow yesterday. It's kind of hard to explain, but our living room has 4 glass doors so you can see the back yard. Birds have been crashing in to the doors for two days now. I think it's because of the snow. It must be reflecting in the doors and they see it and think they can keep going.
Last week, I look outside and there's a bird hanging from it's beak from one of the feeders. He was trying to get a seed that was stuck and jammed his beak in too far and got it stuck. Took me forever, but I finally got him out with a 10" Phillips Screwdriver. I could see how he was stuck from the other side of the feeder, so I stuck the screwdriver in and had to push down on his beak to free him.
Ya know ... he never even thanked me! He just flew off.
He's lucky I found him in the first place. The only reason I did was my wife had just got home from work and told me to go outside and see if I could get a picture of the sky. This is what I got ....
I didn't touch it up, the sky was all purple and orange like that.
