The box involves an infrared light trigger, two cameras, a microphone temperature sensors and a radio-frequency ID reader.

Gathering video from nest boxes isn’t new, Charles Eldermire, Bird Cams project leader at the Cornell Lab of Ornithology, tells Audubon, but using several sensors is a novel approach. More than 30 of these boxes have gone up throughout the Czech Republic and Poland, recording over 300,000 videos available online at
