Night Vision Birdhouse Camera
We found this incredibly nifty night vision bird house and nest box camera sold by Windy City Parrot. The Night Owl™ is an infrared night vision nest camera. You do have to run a cable to your television or computer, but once you do that, you can monitor all the activity in a bird house, bat house, squirrel house or nesting box. The Night Owl infrared camera uses a wide angle lens with a depth of field from one-quarter inch to infinity. This assures that you should be able to monitor all the activity in the box and no matter where the little critters are located, the images should be in focus.

The camera has six mini infrared diodes that bathe the inside of the birdhouse with invisible infrared light. While the human eye cannot see infrared light, the camera is sensitive to infrared and thus can see all the activity. It also comes with a built-in microphone and 100 feet of plug-and-play cable. This means that you can monitor the sounds as well as the sights. Extension cables are available if you need to locate your bird or squirrel house more than 100 feet away.
You can find this and many other bird-related gadgets at Windy City Parrot.
