March Owls:

Barred Owls aren't typically found in SW Ontario, but this year they have been spotted at a few different locations.

They are large, stocky owls with rounded heads, no ear tufts, and medium length, rounded tails. They are a slightly smaller than Great Horned Owls.

Barred Owls mostly eat small mammals like mice and voles. Sometimes they go fishing for crayfish and crabs. If a Barred Owl eats enough crayfish, the feathers under its wings can turn pink - just like a flamingo which gets it hue from the high volume of shrimp in its diet!

A Red phase Eastern Screech Owl can sometimes be seen poking out of a tree cavity.

The presence of a Great Horned Owl in Canatara Park was made obvious by a "murder" of 22 American Crows. The crows harassed the owl before it finally flew away.
