Spot the difference!

R: What kind of bird are you?
L: I’m a starling!
R: You can’t be. You’re not brown!
L: Well I am. My dad was a starling and my mum was a starling so I’m a starling.
R: So how come you’re nor brown?
L: Because I’m almost white!
R: I can see that. Do you want to borrow some spray tan?
L: No thanks. I quite like being different. And I’m easy to pick out in a crowd as you can see in the extra!
