[Ontbirds]Peregrine in Scarborough

[Dave Bailey]

At approximately 3:30pm, Sunday March 23 I observed what I am sure was a Peregrine Falcon interacting with a Red-tailed Hawk above the northwest corner of the intersection of Highway 401 and Markham Rd. in Scarborough. The Peregrine was not stooping, just doing some short dives and circles around the less agile Red-tailed. Having fun? Hunting? (unlikely) Defending a possible nesting site? (more likely, IMHO) Details are sparse because I was also dodging and watching for other vehicles at about 110 kmh, but judging by the size compared to the hawk I would presume that it was a female.

Markham Road is at exit 383 from either direction on Highway 401.
