This GIANT tube feeder by Droll Yankees is the perfect solution for the “Always Filling The Feeder” syndrome.  The B-7F 20" Tube Feeder is great for busy feeding stations, hard-to-access locations, or weekend vacation homes (fill it up on Sunday as you leave & still have seed (and birds) when you return on Friday).  It features all-metal components, 3˝” diameter polycarbonate tubing, and a threaded base for adding a tray.  Made in the USA.
