Little Tern Sterna albifrons

This delightful chattering seabird is the UK's smallest tern. It is short-tailed and has a fast flight. Its bill is a distinctive yellow with a black tip. It is noisy at its breeding colony where courtship starts with an aerial display involving the male calling and carrying a fish to attract a mate. Image: Arthur Grosset (Flickr).
