  Hold my earlier thought Zo!
  
  The Gulls may well gather together in flotillas of/for familial recognition for ‘security’ purposes, but there could also be another reason for their ‘migration’ between ‘land’ and ‘sea’ on a diurnal timescale!
  
  ‘Thermal capacity’!
  
  ‘The sea (water)’ takes ‘a longer time’ to warm during ‘spring and summer’ and ‘a longer time’ to cool during ‘autumn and winter’ WRT ‘any land surface’. Thus, these Gulls only seem to seek a ‘climate’ that best suits their ‘metabolism/lifestyle of the day’.
  
  Our recent ‘frosts’ in the UK lead me to think about this subject and I believe that the Gulls may well migrate to the sea at night because the sea was ‘warmer than the land’ during our ‘overnight frosts’. Similarly, I could also presume that, during the ‘hot season’, the Gulls may want to ‘cool’ in the sea.
  
  This leaves ‘spring and autumn’. ‘Spring’ is the season for ‘laying eggs’ and ‘autumn’ is the season for ‘educating the offspring’.
  
  Your thoughts?
  
  Kind regards, Ray Dart (AKA suricat).
