I don't run on the paths every day and I never run the same route two days in a row for fear of encountering a creeper. But the days that I do run the paths I enjoy taking in all of the amazing scenery.
Here is a partial list of the wildlife that I've enjoyed watching throughout my summer runs:
Animals
Deer (one so close the other day I could have reached out from the path and touched it)
Chipmunks
Squirrels
Groundhogs
Birds- and this is just a small list, I cannot identify all of them- but I kinda want to take up bird watching as a hobby now (who cares if I am not a retired old man)

Bluejays - my personal favorite
Cardinals
Orioles
Crows
Kingfishers
Sparrows
Woodpeckers
Morning Doves
Carolina Chickadees
and lots of different butterflies.
Anyone have a favorite place to run?
