Zašto kondor, orao, sup i sl, imaju na vrhovima krila pera koja pojedinačno strše, a galeb, albatros, čigra i sl. nemaju?

zbog soli u zraku, morski zrak ima drugaciji efekt na profil krila  ;)
ako gledamo sa druge strane orao,sup, kondor su scale modeli pa imaju flapove a galeb,albatros,čigra su parkflayeri pa ima ne trebaju flapovi
