This cleverly designed feeder is great for birds but a real foe to squirrels. A weight-activated mechanism cuts off the food supply when the trigger weight is reached. The trigger weight can also be set to stop larger birds from feeding. It has a large seed capacity of 1.5 kg, six feeding ports and a ventilation system to keep seed fresh and dry. Easy to dismantle for cleaning and carries a lifetime manufacturer's warranty. 50 cm tall.
