Not my usual area but I've been going down a rabbit hole with trail cam footage lately and honestly some of it is wild. Would love to see what you've got - the way light and shadows interact with cameras like that can throw up some really weird shapes that are hard to explain away.
Had a mate in Shropshire (my neck of the woods) who caught something on his garden cam a while back. Tall, dark, moved in a really odd way. He wrote it off as a person but the proportions were just... off. Never quite sat right with me.
Post the footage if you can. Still image vs video makes a big difference for these things, in my experience even a few frames of movement tells you way more than a single shot. What time of night was it and did the cam pick up any sound?
