The western swamphen prefers wet areas with high rainfall, swamps, lake edges and damp pastures. The birds often live in pairs and larger communities. It clambers through the reeds, eating the tender shoots and vegetable-like matter. They have been known to eat eggs, ducklings, small fish and invertebrates such as snails. They have even been known to attack large eels; however, there is no consensus amongst ornithologists if they actually eat eel. They will often use one foot to bring food to their mouth rather than eat it on the ground. Where they are not persecuted they can become tame and be readily seen in towns and cities.
Swamphens were often kept in captivity in ancient Greece and ancient Rome. The behavior of the species was described in some detail by Aristotle in History of Animals (4th century BC), and they were also mentioned by Aristophanes (5th century BC), Pliny the Elder (1st century BC), Aelian and Athenaeus (2nd to 3rd century AD). Sources indicate that these birds typically were western swamphens (originating from the Balearic Islands, among others) or grey-headed swamphens (originating from Turkey), and the two were already distinguished by Pliny the Elder who considered the former superior. They typically were not kept for food, but instead were decorative birds in villas and temples. If raised in captivity swamphens tend to become quite tame. There are many depictions of the species on Roman mosaics and frescos, typically in a natural or domestic environment, including the famous garden fresco from Pompeii. In early Christianity it was also frequently depicted, but here symbolising the richness of life and often perched in the tree of life.
