Red-billed seagulls, as the name suggests, are red-orange in their beaks and red-orange in their two claws. Most of the body is pure white with a black tail. The size is about the same size as the pigeons, so Kunming people call it the "water pigeon". In this Kunming city, there are two places where the most concentrated seagulls are gathered. One is Dianchi Lake and the other is Green Lake.
