If you are feeding birds, it is probably because you like them. Otherwise why do it? While some backyard birdwatchers welcome all birds to their feeders, for many of us, there are birds that are less welcome. Some people don’t like House Finches. Some don’t like House Sparrows. Others draw the line at Brown-Headed Cowbirds. Red-Winged Blackbirds? European Starlings? Common Grackles? Your list may vary. What birds at your feeders do you consider nuisance birds?
