Abstract
In a wild bird trap, a pair of control housings are recessed in the surface of the earth or disposed below the surface of a body of water which respectively support a pair of horizontal net arms when the trap is in unsprung position. A section of netting extends between and is connected with the pairs of arms. Housing contained pressure cylinders, connected with the respective net arms, are connected with a source of fluid under pressure through a solenoid valve opened in response to closing a circuit in a remote concealed location for actuating the cylinders and springing the trap.
