Dodos fed primarily on plants, seeds and fruits that grew naturally on Mauritius, they were herbivorous. They would swallow small rock pellets to help grind the food they ate and optimize their digestion system. (This might be UN true because no one has seen a dodo for over 300 years). Dodos were able to breed all year round. Some scientists, believe that once a male and a female would mate, they would stay together for life, thus they would take care of their chicks once the egg would hatch
