If you like to see what happened during exactly 0.5 second when two Forster âs Terns attacked together a school of fish look here: _http://www.pbase.com/image/148856471_ (http://www.pbase.com/image/148856471) You can try to find two single tern plunge-dive paths - it should be easy, well sort of. Made from set of 5 photos taken 1/8 second apart. So many things were happening last Sunday.
