A mesh feeder for dispensing sunflower and similar sized treats, the birds retrieve each item by pulling them through the mesh. There are no ports, making it more difficult (though not impossible) for squirrels and large birds to eat from the feeder. The feeder can serve sunflower (with or without shells), safflower, peanut pieces (pieces, not halves), dried fruit, and any other similar sized items.
Who you attract depends on the food you offer, but chickadees, nuthatches, woodpeckers, and finches are all within reason.
Holds about three pounds of seed.
Approximate dimensions: body at largest point ~ 8"D x ~ 11"H, hanging loop adds about 4" to height.
