Abstract: A pair of Black-capped Chickadees undertook nesting in early July, late in the local breeding season of this species, in a suburban garden in Surrey, southwestern British Columbia. Two eggs hatched after a delayed incubation of 17–20 days, four to seven days longer than normal. Delayed incubation is discussed. The two young fledged during the afternoon, an unusual time of day.

Key words: Black-capped Chickadee, delayed incubation, Poecile atricapillus, southwestern British Columbia
