- It is natural behavior for male budgies to guard the nest during the breeding season.
- The male budgie will typically perch in front of the nest box and keep an eye out for any potential threats, such as other birds or animals.
- He may also sing and chirp to attract the female and defend his territory.
- The female budgie will typically climb around the nest box and gather nesting material, such as twigs, grass, and feathers. She will also lay her eggs in the nest box and incubate them until they hatch.
