A few weeks ago, I was walking up on the national forest and found this collection of Fluff on the ground.
Up close, it looked like rabbit fluff.
I think that a raptor, such as a red-tailed hawk, smacked down a cottontail rabbit there and tore it open to eat it, but I cannot be sure. The almost circular pattern of the distributed fluff seems to suggest a bird to me rather than a four-footed predator
Dinos 1, Mammals 0 in this case?
