Two males paired up?

[jmaxpsi]

Ok, I have 2 pigeons that I believe are paired up. The more aggressive one in which I thought was a male and actually mated with the other less aggressive one. Then another day, the other one in which I thought was a female was on top of the male and mated. Can anyone explain why the male laid down and let the other one mate? Each time that I saw them mate, it was a successful and complete mating ritual. The one that I thought was a female is a young bird. It always follow the call of the older bird. As of today they are looking for the right box to build a nest. The OB coos and hides and the YB comes looking. Thanks for any comments.
