Shiny Pidgeys

Earlier this year, in June, I was out for a walk and came across three unique looking pigeons. I couldn't help but take a bunch of pictures! I had never seen Pigeons that looked like this and to see three different looking ones all at once seemed like a rare find.
(I would have gotten all the points in Pokémon Snap)

Here are the three of them together:

Those who are different seem to stick together:

I think my picture taking was making the grey & white one nervous, it started to wander away:

The other two didn't seem as cautious though:

What's behind here?

Pretty bird

"I've got my eye on you"

Grey/white slightly less worried:

Brown one knows they're beautiful:

Came a bit closer to show off:

Sassy runway walk:

Me too:

The white one spotted something:

Tasty grass:

I think the brown one liked me:

The pigeons in my area usually look like this:

I had never seen pigeons that looked different from the typical ones shown in the last photo, if you know what their colour mutations are called please feel free to let me know in a comment below!
