One thing I have always been very interested in to improve my wildlife photography is wildlife camera trapping. With camera trapping, you set up a camera in a small box and place two movement sensors where you expect the wildlife that you want to capture to walk by. Once the animals walk through these sensors, the camera will take a picture. Sounds pretty easy but in reality, it is one of the hardest ways of taking pictures! But it is an extremely powerful tool in wildlife conservation. Through with camera trapping, you can get pictures of very shy animals that you usually would not be able to get close to.
One photographer that does a lot of camera trapping is Steve Winter. He especially focuses on big cats. Through his camera trap images, he was able to capture never before seen behavior of snow leopards, clouded leopards, and even the rarest cat on our planet, the beautiful Amur leopard.
I am planning on using camera trapping once I move up to Montana. A goal of mine has always been getting a image of a wild mountain lion. It is incredibly hard to see them in the wild as they are very shy, but camera trapping enables you to take images without you actually being there and without stressing the animal out
