Prof Daniel Pauly, at the University of British Columbia in Canada and who led the work, said the decline is very strong and "is due to countries having fished too much and having exhausted one fishery after another." Prof Boris Worm, at Dalhousie University in Canada and not involved in the new research said."This was a Herculean task that no one else has ever attempted.Seafood is the critical source of protein for more than 2.5 billion people, but over-exploitation is cutting the catch by more than 1 million tons a year.Official catch data from FAO rarely includes small-scale, sport or illegal fishing and does not count fish discarded at sea.Paleczny and Hammil's research found that the tern family has fallen by 85%, frigatebirds by 81%, petrels and shearwaters by 79%, and albatrosses by 69%.Lascelles said: "Increased efforts should be made to rid seabird colonies of invasive species, reduce bycatch in fisheries or the ensnaring of birds in fish nets, and setting up conservation areas." Paleczny also called for the creation of international marine protected areas to cover the wide ranges of seabirds.

Seabirds have been around for sixty million years, and they are true survivalists: circumnavigating the globe without rest, diving more than 200 meters in treacherous seas for food, braving unpredictable weather and finding their way with few, if any, landmarks.
