1.25-quart capacity. Aspects' Seed Tube Feeders combine heavy,, die cast metal caps,, ports,, bases and a clear U.V. stabilized polycarbonate tube to make these feeders an investment that lasts a lifetime. A built in seed deflector in the base allows birds to remove every last seed. Redesigned feed ports on the seed tube model have a raised ridge to divert rainwater and perches are part of the seed port. Add a seed tray to attract more birds,, and protect the feeder from the elements with an Aspects dome.
