text: There are two main groups, the ‘sea’ terns (not always strictly marine), which look pale grey and white except for a black cap in summer, have long tail streamers and dive to catch fish, and the ‘marsh terns’, which are blunt-tailed, almost black underneath in summer, and dip to pick their food from the surface without diving.
