I have (had) a pair of modenas and they raised a few clutches of babies together this summer. I also have a couple of utility kings that I picked up at one point this summer, I wasn't sure gender on them when I picked them out, just picked them from someone's flock.... Well, my Ma modena decided to have an affair and started dating one of the kings! For all intents and purposes it looks as though she has divorced her husband and married the king, as they now hang out together and sleep in the same place and Pa modena is out in the cold..... I thought it was pretty weird that she up and dumped her long-time mate. The kings had been around for quite some time before this mate-swapping took place, it didn't happen as soon as they showed up or anything. Oh, and one other detail, was that after having been here for quite a while, the king had run the modena pair off from what had been their nesting and roosting area and it would sit up there at night and Ma and Pa modena had to take up other accomodations. So after that housing situation had gone on for a little while, one day I found the king and Ma modena sitting in the nest cooing with each other. Maybe she loved her old house more than she loved Pa and dumped him for the king to get to move back in. LOL Is it unusual for pigeons to swap mates of their own volition?
