Glowing green thing or animal in my backyard

This is the second time I’ve seen this in my backyard and it’s only out at night, I live in the country on a acre of land and I was outside wetting down a extinguished bonfire then I saw it. I don’t think it’s a animals eyes reflecting because I would’ve been able to tell it was eyes and it was completely dark out but it’s just very bright green. It was moving around the tree line getting closer to me.
