Unlike last year, house sparrows have been a problem at my backyard feeder this year, depleting precious sunflower seeds and, in my opinion, displacing other native regular visitors.
So I've kept the feeder empty for the last five-plus weeks. I haven't seen house sparrows at the feeder lately either. Should I wait a little longer until the location-based memory is completely erased in those pesky birds?
