There is at least one Anna's Hummingbird at Paulik Park in Richmond. One or more overwintered there last year, despite the very harsh weather of December and January. This species has been spreading north from its historical southern range for many years, and is becoming a winter resident in many localities in BC.
They were absent from the park during the breeding season. It's odd to think of their return as a sign of winter, but that's what it is.
