Cockatiel breeding behavior
I have two cockatiel pairs in avariy and one pair lays eggs. So now the other pair are also preparing themselves for eggs. They mate and go inside there box. But there is one problem every day before sunset the male and female make lot of piercing squawks. After sunset female sleep inside box and male outside. So why are they making too much noise. My other cockatiel pair didn’t show this behavior and also they didn’t make lot of noise.
