A man filmed a pigeon eating seeds. At normal speed, the bird appears to be eating erratically, scattering seeds everywhere. It almost seems like it can't target or choose its seeds randomly. But when viewed in slow motion, everything becomes much clearer.

Each seed is actually carefully inspected before being eaten or thrown away. The pigeon makes extremely fast and precise movements with its beak, giving the impression that he is seriously 'judging' each seed before making his decision.
