Can colorful birds digest for their own food?

Colorful birds cannot digest themselves.It is northern in the north of Australia. The feathers have many feathers and are more lively. They are very suitable for raising as ornamental birds.I like to make groups of activities, usually the nest is built in a tree hole or a shrub. I like to dry and high temperature environment. Usually, the seeds of plants, buds and insects are eaten.Essence
