A metastable, motion generating squirrel feeder with a pair of coupled, generally V-shaped ribs attracts squirrels with corncobs secured at each rib end. Each rib has a pair of projecting wings symmetrically diverging away from a central vertex. The wings terminate in ends occupying the vertices of a virtual tetrahedron. Notches in the rib vertices enable rib coupling during assembly. Spaced-apart feed holders mounted on the wings each have a fixed bracket and a slidable bracket. Spikes projecting from each bracket towards the other captivate feed such as corncobs sandwiched between the brackets. A mounting ring non-rigidly captivates the vertice region of the ribs, loosely mounting the feeder and suspending it above ground so that the ribs are free to rotate and move in response to squirrels.
