I was checking e-Bird for observations of Bohemian Waxwing near Toronto this year.
Toronto: 1 report (Mar 25, near Don Valley Pkwy)
Southern York region: about 10-15 report (several in Markham in mid-March, several at Lake Wilcox in Jan/Feb, 1 Royal Orchard Apr 6, 1 King City Mar 26)
Durham region: about 20 reports in Oshawa and north of the cities.
Brampton: 1 report Apr 3
Mississauga: 1 report Apr 7
Obviously there are a lot of flocks around that don't get reported, but they aren't seen very often around here, even a big invasion year like this one.
