The term 'Beach Flier' refers to three different types of birds that can be seen flying near beaches. The first is a KITE, which is a type of raptor with long wings and a forked tail. The second is a TERN, which is a small seabird with a long, pointed bill and long, narrow wings. Finally, the third is a SEAGULL, which is a large, white bird with a hooked bill and webbed feet. All three of these birds can be seen flying near beaches, making them beach fliers.
