Terns are a group of generally medium to large seabirds typically with gray or white plumage, often with black markings on the head.

Beak angle ratio is defined as the top angle divided by the side angle. When the top and side angles are similar together, high beak angle ratios result, while when the difference is greater, low beak angle ratios result. Plunge-diving birds' foraging behavior also affects the evolution of rhamphotheca and skeletal beak shape.
