Canaries gender question

[miraeseb]

Hi,

we got these 2 birds last year in May (2020) and we were told that they are 3-4 months and that they are a male and a female. So we named them Mira (female) - the brown one and a bit smaller and Seb (male) - the yellow one. They are a bit older than a year now and we still cannot tell if Mira is indeed a girl and Seb a boy.

We had them together in a cage when we saw that in middle of February 2021 they started having fights. Nothing major (later we saw major fights...), so we placed a paper wall in the middle but they would mutually create holes in it and most of the times I would find Mira in the Seb´s half part of the cage. Most of the times, they were just hanging out ok together (in half of the cage). I would replace the paper wall but they would still open holes and stay together but as the time passed, they would fight more often and longer. They started also making a lot of new voices.

Seeing the situation and not wanting them to get hurt, we got a bigger cage with a separation. They were still getting angry and fight through the bars, so I added paper on the bars, cause I didn´t want them to hurt each other with their beaks and again they would make holes in the paper to see each other.

About them

Seb: the one we were told is a boy - sings a lot and long. I think he could sing almost non stop all the day, if Mira wouldn´t get angry (or at least, this is what I think). He eats more, he is less aggressive most of the times, he has longer showers and when I put nesting material, he just takes it and in 5 seconds he just lets it fall on the bottom of the cage. He is more curious than Mira and he comes to eat salad from my hand really easier than Mira. He will explore everything faster than Mira. In the beginning when I was giving them salad with my hand inside the cage, he was trying to escape the cage, taking his head outside the cage between the bars. Sometimes when Mira is aggressive, he just doesn´t look at her and like this they do not fight.

Mira: the one we were told is a girl - she also sings. Makes all the voices that Seb makes but she doesn´t sing that much. Let´s say she sings less than 1/3 that Seb does throughout the day. She is really aggressive and when Seb sings sometimes she does everything she can to make him stop, like falling on the ground making extra noise. When I put them together, she will be the one to get angry after a while. She needs really more time to trust me and come eat from my hand and she will do it most of the times after Seb has already done it. She gets the hair of the head more often vertical like being excited or afraid. If Seb flies away from the cage somewhere that she cannot see him ( I let them fly free since I got the new cage), she get very anxious. I can make also here a video.

Last but not least, they are being also sweet to each other.I think they are feeding each other but I am not sure:

But they both sing:

And they fight:

But they can also stay together without problems but Mira at some point will get aggressive and I am separating them. I let them without the division, only when I can stay there with them and I am doing it, cause like this, they have more space horizontally also. When Mira gets aggressive I put the division again.

I am sorry for the long text. What do you think? Are they a boy and a girl or both boys? Can 2 boys feed each other? I guess it cannot be that I got 2 females that are both singing.

Thank you in advance for your help,!
