We have a camera trap, or trail cam. It is waterproof, and straps to a tree, and is triggered by motion. We have left it in one spot at the far end of our garden for a couple of weeks, and these are a selection of the best photos. The night time shots are blurry due to the difficulty of taking photos at night without using lights which would scare off the animals. I think it is exciting to see what happens when we are not there.
There were quite a few pictures of deer, with a maximum of four in one shot. Most were a bit of a head, or a backside, or a blur of fast-moving shapes. I am still waiting for a group shot of deer grazing in daylight. That would be very nice!
