Abstract
A bird feeding system may include a platform that is sized and configured to catch at least a portion of the bird feed that may fall from a bird feeder. The platform may include a frame and a catching portion, which may have a permeable construction. The frame may be configured to be moved between a collapsed position for storage and an expanded position for use. Advantageously, the platform may be connected to different types and configurations of bird feeders and/or other structures using attachment members that are adjustable in length.
