I guess we've always known that our two male cockatiels went both ways, but we just caught them actually mating with each other. I got it on camera:
The thing is, the smaller bird (all yellow) was crying out and trying to get the thing off. He couldn't get the greyish bird off until we intervened. (Were they actually penetrating? Does this hurt them?) And why are they mating with each other when there is a female, that is laying eggs, in the cage?
Originally we just had the female in the yellow one. We found the yellow/grey one abandoned and took him in. Shortly after, we noticed that the yellow one was acting the way he did to his "wife" to the new bird. He did all the preening, neck hugs, etc. But they never mated. And both birds would regularly have sex with the female.
When the female lays eggs on her nest, she shows little to no interest in them. However, when she does try to go into the nesting box we set up, the guys won't let there. They will be in there both sitting on the eggs, and will attack her if she gets too close.
And, when they separate the two guys, they freak out and scream at each other. They go on for hours.
Help? What is going on?
