What do dodos eat?

Could you please elaborate on the dietary habits of dodos? I'm particularly interested in knowing what types of food they consumed in their natural habitat and if there are any specific dietary requirements or preferences that we know of? Additionally, I'm curious to learn about any adaptations they may have had in their beak or digestive system that allowed them to consume certain types of food. Could you also discuss any potential implications these dietary habits may have had on their extinction?
