Abstract: A bird feeder for preventing rodents from grabbing bird seed in the bird feeder. The feeder includes a silo having a first end and a second end with an opening to permit seed to flow onto a supporting tray below the silo. A conically shaped cover is attached adjacent the silo. The cover extends outward in a substantially straight line from a narrow portion which is connected to the top of the silo to a wide portion. The straight line terminates the cover in the wide portion. The diameter of the perimeter of the wide portion, has a ratio selected with respect to the diameter of the perimeter of the feeder tray, to prevent rodents from accessing the feeder.
