I set up a mini IR camera in my chickadee house. It's hooked directly to my TV so I can watch the nest anytime, and make videos like this: like this. I was watching yesterday and my cat walks up and takes a seat. I thought it was cute!
Here's a shot of the camera in the box. For anyone who's interested, I got the camera from here. Fun to watch, and I can't wait for the eggs to hatch. One thing that's interesting is that this is the second brood of chickadees this season in this box. Apparently that's quite rare, assuming it's the same pair of birds.
What a clever idea! I LOLd when I saw the kitty watching the bird on TV. It's funny, I have an indoor cat also but she's always in the window watching the birds. I sometimes hear her "talking" to them.
