The No/No Finch Feeder has a green and black finish and doesn"t contain any wood or plastic! Each opening in the metal mesh sidewalls becomes a seed station for birds using the No/No Finch Feeder. The largest amount of feeding surface in the bird feeder industry! The feeder holds approximately two pounds of nyjer (thistle) seed. The unique baffle device helps keep feed at upper levels instead of letting then run "dry" as birds deplete the seed. This means more birds at breakfast, lunch, and supper. It ends the fighting over just a few feeding windows. When filled with nyjer seed, the time-tested mesh housing will attract finches, chickadees, nuthatches, juncos, and other clingers, perchers and trough-feeding birds. The all-metal No/No Finch Feeder was developed by birders who know wild birds and the people who feed them. It"s a no-nonsense technical upgrade from traditional tube feeders...sturdy yet stylish, with an attractive shape and colorful design. Hang or post-mount your feeder. The roof and tray easily detach for refilling or cleaning. Feeds up to 15 birds at a time and the wire mesh design helps protect against avian diseases!
