They like to scatter their food all over the room as much as possible
If it is a parrot like an African Grey, they need to have a balanced diet of pellets (you can get from a pet store) and plenty of fruit (apples, oranges, mielies, etc). Sunflower seeds are VERY unhealthy for birds so that can be used as a treat. Smaller parrots/parakeets mainly have seed diets and your pet store will be able to recommend a food for them. :)
Foods are listed as fruit/vegetable only. Any safe plant parts will be noted (e.g. "Carrots and carrot greens").
