Some member of the birdie public are up to of truly amazing feats fromflying without flappingfor over five hours , tonot stopping flyingfor over 10 square months . However , all that time in the air can make even the most seasoned flier weary – so where do birds rest when they are fly over the ocean ? Let ’s take a look .
For some hiss , the best strategy is not stopping at all . Astudy from 2021looked at five specie that flew long distances during their crepuscle migration and found that these soaring species , which include the peregrine falcon ( Falco peregrinus ) and the osprey ( Pandion haliaetus ) , relied on static wind stipulation to create uplift that helped them save energy for their long journeys .
“ Until of late , uplift was assume to be weak or absent over the sea surface . We show that is not the guinea pig , ” lead author Elham Nourani said in astatement . “ rather , we find that migrant birds adjust their flight of stairs routes to profit from the best hint and uplift condition when they fly over the ocean . This facilitate them sustain flight for hundreds of kilometers . ”
It is guess that 2,000 coinage – or 20 per centum of the total act of razzing in the world – are even migrator , according to the RSBP , though some put the numbers even higher . While some land migrant have designated barricade areas that have been used for generations , researchers are find a higher figure of birds using ships as repose boodle than was previously thought .
“ stop on ships is regard an special and anecdotic event in the ornithological lit , ” write the authors of apaper bring out in 2022 . However , these research worker carried out an oceanography crusade within the Mediterranean Sea and show 13 unlike metal money of fowl discontinue on their boat during their 25 - daylight expedition .
The team found that the median length of time thebirdsstopped on their boat was 42 minutes , and think the prison term may be relatively short because of a lack of solid food resources that birds could forage on their boat . However , the team believe that most of the birds chose to stop either because they faced bad weather or were in physically poor condition and needed torest .
By using their data on the boo , they estimate that almost 4 million birds could habituate ships in the central Mediterranean as layover site , suggest that more research call for to be carry out on the wallop of marine traffic on autumn migration .
