Aspects' Bigfoot Round Seed Tray works well on a pole-mounted feeder as well as on a hanging feeder. Instructions are included for either mount. This seed tray can be used on a variety of tube feeders, including the Aspects Seed Tube, Thistle feeders, and Big Tube; Droll Yankees A-6 and B-7 series feeders; and Vari-Crafts two and three quart feeders with threaded base hole. Adding a seed tray will allow more of the seed to be eaten at the feeder and less scattered on the ground.
