I wondered about that myself. According to Wikipedia: All mute swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water. The grey color makes you wonder what is in the Thames. 🙂
What a spectacular picture of these beautiful birds! Well captured!

Considering most of their time is spent in the water ducking and diving I was amused to note they have dirty necks!
Good line-up, thank you 🙂
