That is hair from a dead White-tailed Deer.
If you look around the area, you might be able to find the bones from the remains. These hairs in particular are likely from the tail. The only animal in your area that has hair of this color that is likely to be found in your area is the White-tailed Deer.
I commonly come across areas like this in the spring time.
Update:
Here is a similar photo that I took with a cool beetle.
