Yes, a cucco riding the ground.
I just discovered a nice text skip. In the Lost Woods, when going from the area where you play your ocarina with the Skull Kids to the Goron City warp, if you face the "arch" leading to the warp and hug the left side, you can walk in a straight line to the warp without activating the owl text.
EDIT: Here is the best method for getting from Kokiri Forest to Goron City:
Exit house.
Backflip.
Backwalk until right before ledge, then run into it and pull yourself up.
Roll to vine, climb up.
Turn around, backwalk straight ahead.
Sidehop right, angle yourself, backwalk and sidehop into arch.
Lost Woods:
Turn around.
Backwalk.
Sidehop left 8 times.
Diagonal walk left for a short time.
Backwalk into the warp.
