Hi irwan,
ur gglb song is good but i think it's not the territorial song which is more melodious and hard long rolling ear piching sound with aggresive wing display. Why not u try to put a mirror for a while to see ur gglb reaction with other male image. This normally done to make gglb more fierce n confident with their territory cause in the wild the gglb is a territorial bird. But if u have more than 1 gglb in one place don't let it see each other too often or just half covered the cage.
regards.
