Cada año vuela frente a las costas noroccidentales de la península Ibérica buena parte de las poblaciones de algunas especies de aves que tienen sus colonias en el norte de las islas Británicas. La temporada reproductora de este año de la gaviota tridáctila, el págalo parásito y el charrán ártico ha sido "terrible" (sic) según la RSPB y BirdLife International. La falta de alimento debida al cambio climático se apunta como la causa principal.
la nota de prensa difundida por BirdLife International dice que "The new RSPB data confirm that many northern species have suffered major collapses in breeding success. Worryingly, the evidence again suggests that repeated annual breeding failures are now substantially reducing populations of those species worst affected".
La situación en Islandia no es mejor: "Icelandic seabirds are also experiencing similar problems. Fuglavernd (BirdLife in Iceland) reports that many seabirds have had extremely bad breeding seasons over the last four years. Icelandic seabird declines have coincided with a period of rapid increases in sea temperature - especially in south and west Iceland which is most exposed to the warming waters of the Gulfstream.
As in the UK, species which have suffered most are Arctic Terns, Black-legged Kittiwake, Atlantic Puffin, Great Skua and Northern Fulmar Fulmarus glacialis. Due to climate change, 18 new bird species have arrived in Iceland since the 19th Century".
