National Trust Green Metal Squirrel FeederAll the squirrel has to do is lift the lid and take food as required as, much simpler than stealing from a bird feeder! Just be patient and give them a chance to work it out. Discourage squirrels from raiding and damaging bird feeders by providing them with their own dedicated feeder which offers easy access to food.
