I am constantly impressed by this birdfeeder that automatically refills and adjusts to the seasons; self-cleaning too.  I have several of these and I especially enjoy bird watching in September. The design is beautifully organic and made from 100% sustainable natural material. It also has a seasonal timer with a bee and butterfly feeding feature. You can get one free if you have a friend who already has one, or you can find yours by searching any sustainable organic seed/plant source for: ECHINACEA AUGUSTIFOLIA or ECHINACEA PURPUREA. ( I love to get mine online from Horizon Herbs @ horizonherbs.com. Easy installation: plant seed, water, and watch.
