Yellow-rumped warbler.
Another from the archives, so ready for spring. Yellow-rumped warbler. October 7, 2023, Rondeau Provincial Park, Ontario, Canada, in our yard. Setophaga coronata Yellow-rumped Warblers winter across much of central and southeastern U.S., and they sometimes come to backyards if food is offered. To attract them, try putting out sunflower seed, raisins, suet, and peanut butter.
