Male Cockatiel is Nesting in his box, without mating

Why is my Cockatiel (Male) nesting in the box with nesting prior ?

He is overly protective and limits his exposure outside of the box.


Hi Yousaf,

I want to confirm that you have a male and female together, with a nest box? A single bird should not be given a nest box. If you have a male and female, and are trying to breed them, then of course they need the nest box when they are breeding. It is also very important that you only have one pair of birds in the cage – more than one breeding pair can’t share a cage and there should not be any extra birds in the cage. Sometimes with a captive breeding pair, one of the birds will get too territorial. It is more often the male, and he can get so aggressive that he blocks the female from using the nest box. If this is what is going on, and the female hasn’t laid any eggs, then I would recommend taking the nest box down for a short time to see if the male will calm down. Some males remain too aggressive to breed. An aggressive male will constantly attack the female, keep her from the eggs or chicks and then the eggs end up getting broken or the chicks die. It isn’t an option for the female to hatch the eggs on her own. Both the male and female take turns sitting on the eggs. Some birds do not make good breeders. If this male doesn’t calm down, then you probably won’t be able to use him for breeding.

Thank you for asking Lafeber,
