So , that ’s another one the birds have on us . In addition to flying and colorful plumage , they ’re also equipped with gaussmeter beaks that can sensemagnetic fieldsand use them as a map . Yes , even chickens .
Here ’s how it works . The upper beak of birds has nerve branches that contain iron , which may be used to quantify the intensity and tendency of Earth’smagnetic field :
More than about 500 dendrites in the fringe encode the magnetic field information , which is composed in the central queasy system to a magnetic map . It obviously does not matter , whether birds use this magnetic map for their recollective space predilection or do not – the equipment can be incur in migrant birds , like redbreast and garden warbler , and well as in domesticated wimp . “ This determination is astounding , as the birds analyse have a dissimilar sprightliness way and must fulfil diverse orientational tasks : home pigeon , trained to return from unlike tone ending website to their homeloft , myopic - distance migrant like robins , long - space migratory bird like garden warbler and also extreme residents like domesticated chicken ” , explains Gerta Fleissner .
That ’s good : even Chicken Little has a built - in gaussmeter . I get it , birds . You bring home the bacon . Me and my lame opposable thumb are just gon na sulk off into the length . But I ’m not saying where , now that I bed you ’d be able to discover me . [ Eureka AlertviaBoing Boing ]
