Abstract
There are generally two styles of modern bird feeders: the tubular feeder with a tubular reservoir and several perches attached to the tubular reservoir at various positions around the reservoir, and the more traditional rectangular bin style with one or two feeding stations. These bin feeders are constructed to feed only general bird seed of mixed variety and are not selectively configurable to feed a specific small seed like thistle. The disclosed bin feeder includes removable and repositionable bin sidewalls with appropriately shaped upper and lower longitudinal edges to exclusively provide appropriate openings for thistle feed along one of the longitudinal edges or an appropriate opening for generally larger seed along the other of the longitudinal edges.
