These Hand-blown Glass Feeders allow you a full 360˚ view of the birds at work 100% of the time. They are also unusually secure for the birds, as it is nearly impossible for squirrels and other seed-loving rodents to climb into the seed chamber because the all-rounded glass surface is smooth and slippery. The small feeder is 5" in diameter & has one entrance. The large is 7" in diameter (40% larger) & has two entrances. The birds love this food support in the colder months. Into the more rustic look? We also offer birchwood European feeders and homes here.
