Do you think its a buck? those look like points to me... I hope so because this pic was taken about 30yds from my stand yesterday...
Personally, I think it's a leaf. Probably a nice big silver maple leaf that got stuck while falling out off the tree.
how high up from the ground is the cam mounted? Either way, I really don't think those are antlers. Either wing tip feathers or whiskers - I'm leaning whiskers and a neck on the right side.
Bear...they always get so curious over cams. I get pics like that a lot...normally cam is twisted also
