I think it was actually a chipmunk, but I had to swerve a bit to avoid. Little critter and I both escaped unscathed.

Squirrel jumps out from left of road just missing back wheel of rider in front of me. A minute later a young duck at the left side of the road is startled into taking off right across the front of me
