How do I determine the gender of my parakeets?
About a month ago, I brought home a pair of parakeets and a pair of love birds. They seem to get along ( which was quite odd because according to the Internet the two species often fight) and don't cause any trouble. I know that the pair of love birds consists of a male and a female ( the male has a bright orange head and the female's head is more greenish) but I'm not sure about the gender of my parakeets. They are both at least 4 month of age because their heads aren't stripped . One of them has a blue-ish purple cere and the other has just a plain blue cere. I've done my research, and according to the Internet females are supposed to have a tan or brown cere ( which none of them do) but I did find that in some rare cases a female could have a light blue cere. They always feed each other and cuddle ( they even sometimes sing to each other) which I don't find possible if they were both males. If anyone could help me, I'd be so grateful . Thank you .
