Many birds within the order Charadriiformes exhibit bright red or yellow coloration on their bills, feet, eyes, or mouth linings. Specific examples include:1

Oystercatchers (family Haematopodidae): These birds are notable for their long, flattened, bright red bills.23
Gulls and Terns (family Laridae): Members of this family often feature brightly colored red or yellow legs, eyes, and bills.3
Skimmers (family Rynchopidae): These birds possess red or yellow bills, which are sometimes tipped with black.3
