A bird feeder with a movable lid includes a knob which is grippable by the user of the bird feeder to slide the lid along a suspending cable. The knob includes a U-shaped spring with gripping surfaces that grip the cable. This U-shaped spring is firmly trapped between the knob and the upper surfaces of the lid. This assembly permits easy sliding of the lid against the frictional engagement provided by spring bias so that the lid is held down against the filler opening of the feed reservoir that, but can be slid along the cable against the frictional bias of the spring for easy filling.
