Not sure how common this is since I've only been birding semi-seriously for a few years, but for the last week there have been approximately 10-15 Cedar Waxwings calling from trees where I live on the southeast corner of Golfdown and Cove in the Albion/Elmhurst area of north Etobicoke. Also, today I watched about a dozen Chimney Swifts calling as they performed aerobatics over the same area.
