I haven't seen a Scarlet Tanager for years but I've had a few Baltimore Orioles around here each year. On my biking trail off of the Etobicoke creek I've seen them pulling apart tent caterpiller nests, not for the caterpillers but for their own nesting material.
We get Scarlet and Summer Tanager nesting around the house. As for Owls, we have Great Horned, Screech and Barred. The Barred Owls often get into a "conversation" during the Spring & Summer. It is one of the few "Bird Things" that my wife enjoys.
