Adding a seed tray to a bird feeder helps to get the most out of feeding wild birds. The 10.5 in. Omni Seed Tray saves spilled seed, while also helping to attract a larger variety of birds. Adding a seed tray turns a tubular bird feeder into a platform feeder that will attract more species, like ground feeding birds. Its UV stabilized polycarbonate construction is dependably durable. The tray attaches with the included threaded black plug - no tools needed! This tray fits Droll Yankees' Classic, The New Generation, Ring Pull, and Bird Lovers feeders and is proudly made in the USA.
