What can a hidden camera in the woods see?

Have you ever walked in the woods and heard a twig snap behind you? You turned around, and nothing was there. Something heard you coming and slipped away to hide.

Now picture a small camera hiding in the woods, painted brown and green like bark so it looks like part of a tree. So what can a hidden camera in the woods see?

First, a forest ranger straps the camera to a tree beside a narrow animal path. Then the ranger walks far away. Many forest animals stay hidden while people are close by, so the ranger leaves the path quiet and empty for them.

Inside the camera sits a sensor, which means a small part that notices something warm moving in front of it. The camera waits quietly and takes no pictures until its sensor notices something.

When a warm animal steps onto the path, the sensor feels the change and tells the camera to take a picture. Click, click, click! The camera snaps a few pictures in a row, so it catches the animal as it walks past.

In the daytime, the camera sees the animals that use the path in the light. A deer steps along on its thin legs, and a squirrel scampers by with a nut in its mouth. Each one gets its picture because the sensor felt its warm body.

Many forest animals are nocturnal, which means awake at night and asleep during the day. Owls, foxes and raccoons come out when the woods turn dark. A bright flash would frighten them away, so how do you think the camera takes their picture?

The camera shines a special light that our eyes cannot see, but the camera can, so the animal shows up in the dark. When a fox trots by at midnight, the sensor feels its warmth and the camera clicks. The night pictures come out in grey, black and white.

Because no person is standing nearby, the animals behave just as they do when they are alone. The camera sees a mother fox with her cubs tumbling in the leaves. It sees a nocturnal raccoon sniffing the camera with its pointy nose, curious about this strange box on the tree.

Sensor, nocturnal. A hidden camera sees the wild animals that walk past it by day and by night, because its sensor clicks a picture whenever a warm body moves, even when no person is there.

Sleep well, and maybe tonight a little fox is trotting past a quiet camera in the woods.
