You may not have a glass house, but the birds in your backyard can. We love the simplicity of the Glass Haus Bird Feeder from Sprout Home ($56). We haven't seen it in person, but we're big fans of Sprout Home and their garden products.
We're a little nervous about the durability of a glass bird feeder, although the website assures it's "tough enough for beating wings."
We wonder if it's tough enough for squirrels, too. The stopper at the end of the cord is made from rubber, and it looks like the hook at the top can be securely wrapped and fixed around a branch.
We think these are so pretty, they'd make beautiful lanterns, filled with rocks and tea lights.
