We assess the effectiveness of wood pigeons as dispersers of domestic olive seeds.

40.3% of pigeons consumed olive seeds, with a mean of 7.8 seeds per pigeon and day.

Most seed sizes passed undamaged through the gut, with germination rates >10%.

Pigeons can act as long-distance dispersers (>7 km) of cultivated olive trees.

Pigeons facilitate the dispersal of cultivated olive trees into the natural systems.
