Identificaciones de torontoraptor

No hallux, smooth toes, tracks slightly asymmetrical

Scent marking/communication board on tree

Deep holes drilled into the tree

I'm guessing with fair certainty. Tracks came up the steps out of the pond and onto the dock.

Largest track is 9 by 6 cm at widest points

Track length about 3.25" which is at the low range for great horned owl. Tracks seem less bulbous/robust than typical great horned owl tracks though. Barred owl maybe?
