[0] Seabirds CEH; JNCC [WHAT COULD HAPPEN] Some species will have difficulties in adapting to changing prey availability. Long-term climate change will result in a northwards shift in the range of some species and consequently a decline in UK population size. Anticipated sea-level rise and a greater number of more severe storms may reduce available breeding habitat for shoreline-nesting species (e.g. terns) and wash away nests. [WHAT IS ALREADY HAPPENING] 
Poor breeding success and reduced survival of black-legged kittiwakes in recent years have been strongly linked to warmer winters and changes to their fish prey populations (e.g. smaller, less-nutritious sand eels, increased snake pipefish abundance). Other seabird species may have been similarly affected.
