ABSTRACT:
A birdfeeder has a bottom portion for delivering seed to a tray to which birds have access through a fly up entry into a feeding area. The bottom portion includes a dome with a central hole and nearby filling port. There is also a cover with a central hole and a skirt portion which normally covers the filling port. The central holes define a birdfeeder axis. A hanger has a straight portion and a hook portion. The straight portion passes through the central holes and the hook portion is above the cover. An eccentric cover lock has an aperture through which the straight hanger portion passes. Due to its eccentricity, the cover lock is normally held by gravity in a cocked position in which the aperture impositively holds the cover lock at any location on the straight hanger portion above the cover including a lowermost location in which the skirt portion covers the filling port and the cover lock deters the raising of the cover. The feeder also has a spring device engageable with the hook portion and a mounting chain. The spring device suddenly lifts the bottom portion of the birdfeeder when an animal releases its grip on the straight hanger portion attempting thereby to reach the fly up entry.
