Baby Raccoons in a Tree Hollow

I was out birding with my fiance out in the forest and discovered a den of raccoons in a tree hollow. The little guys made a few noises as I looked in the hollow. They seemed pretty curious at first as they approached the opening, they might have though I was their mom returning with food. After sniffing around and determining that I was not their mother they proceeded to climb up the tree hollow. We'll have to go back and check in on these guys as they grow up. They look like they are about half the size of a full grown adult raccoon so far. This was a nice little surprise today I had not idea I would find a den of raccoons randomly in the forest lol.
