Is it me or are there really more birds about in 'non-standard dress'? Not just pigeons but Mallards and Blackbirds etc.
No interactions present.
there have certainly been quite a few posted on this site. But oddities always attract attention, and not just from humans. Odd colourations may make the animal more conspicuous to predators.
In feral pigeons, there is probably a lot of interbreeding with escaped show or racing birds, I guess: and these tend to have unusual colours.
