A project starter

I knew we occasionally have these Roe Deer in the railway cutting but found out this morning how they enter and leave. 

I had to walk just about ~7metres to get from our kitchen door to near the fence, but by the time I was close enough, they had seen or heard me and were away.  Perhaps pick a dry morning and have a tripod set up the previous evening with a remote trigger?

The one waiting to leave went between the top two strands of the fence.
