The ground bird feeder cage is designed especially for the birds that will not feed from tables or feeding stations, such as blackbirds and starlings. Placed on the ground, with food in the provided feeder tray, the larger pigeons, jays, and magpies are unable to get in, leaving the feed for smaller birds to feed in safety. Measuring 50cm across, the cage is 30 cm high and the internal feeder tray is 16cm. Made from powder-coated steel with galvanized hanging chains.
