Abstract
A bird gate for a grain auger outlet includes a panel that extends across the auger outlet in a normal, closed position. It is biased to that position by a spring. When grain is delivered from the auger, it falls on the panel, biasing the panel to an open position and allowing the grain to be delivered from the auger. The closed position of the gate prevents birds from entering the auger for nesting.
