A bird feeder including a shroud embracing a vertically disposed feed container with the feed container having a feed tray at the lower end thereof. The shroud is vertically movable between an upper position and a lower position with respect to the feed container. In its upper position, birds are able to gain access to the feed tray. In its lower position, the shroud blocks access to the feed tray. A spring yieldably maintains the shroud in its upper position. If a squirrel climbs onto the shroud, the weight of the squirrel overcomes the resistance of the spring which results in the shroud moving to its lower position to prevent the squirrel from gaining access to the feed tray. Three different embodiments of the spring are described and shown. The design of the cover of the shroud partially shields the spring from inclement weather.
