Vse predstaviteli zhivotnogo mira - ptit͡sy, ryby, rakoobraznye, reptilii, mlekopitai͡ushchie, nasekomye i dazhe slizeviki sovershai͡ut velikie puteshestvii͡a po vode, sushe ili vozdukhu. Migrat͡sii͡a - odna iz velichaĭshikh taĭn prirodnogo mira. Bez kompasa ili GPS-ustroĭstv ptit͡sy proletai͡ut tysi͡achi kilometrov iz Evropy v Afriku, gde vdovolʹ nasekomykh i i͡agod, lososʹ peresekaet okeany, chtoby vernutʹsi͡a v reki, v kotorykh on rodilsi͡a, a babochki-monarkhi provodi͡at vsi͡u svoi͡u vzroslui͡u zhiznʹ, puteshestvui͡a ot lugov SShA i Kanady do lesov Meksiki. Za svoi͡u 30-letni͡ui͡u zhiznʹ poli͡arnai͡a krachka proletaet rasstoi͡anie, ravnoe pi͡ati poletam na Lunu i obratno. V ėtoĭ knige podrobno rassmatrivaetsi͡a, kak i pochemu migrirui͡ut raznye zhivotnye. Prostoĭ tekst napolnen uvlekatelʹnymi faktami, a krasochnye illi͡ustrat͡sii pokazyvai͡ut chudesa nasheĭ neobyknovennoĭ planety i vidov, naseli͡ai͡ushchikh ee. Kozhistye morskie cherepakhi - odni iz samykh zakalennykh pokoriteleĭ okeana. Vmeste s morskimi techenii͡ami oni plyvut v poiskakh vkusnykh meduz i preodolevai͡ut do 17 000 km v god, a potom vozvrashchai͡utsi͡a, chtoby otlozhitʹ i͡aĭt͡sa na tom samom pli͡azhe, gde rodilisʹ. Pari͡ashchie ptit͡sy ogranicheny vysotoĭ termicheskikh potokov, a mashushchie mogut letatʹ na bolʹshikh vysotakh. Vot pochemu my redko vidim mnogo melkikh pereletnykh ptit͡s; obychno oni leti͡at tak vysoko, chto s zemli ikh prosto ne vidno.

All representatives of the animal world — birds, fish, crustaceans, reptiles, mammals, insects and even slime molds make great journeys by water, land or air. Migration is one of the greatest mysteries of the natural world. Without a compass or GPS devices, birds fly thousands of kilometers from Europe to Africa, where insects and berries abound, salmon cross oceans to return to the rivers in which they were born, and monarch butterflies spend their entire adult lives traveling from the meadows of the United States and Canada to the forests of Mexico. During its 30-year life, the polar tern flies a distance equal to five flights to the moon and back. This book examines in detail how and why different animals migrate. The simple text is filled with fascinating facts, and colorful illustrations show the wonders of our extraordinary planet and the species that inhabit it. Leatherback sea turtles are one of the most seasoned ocean explorers. Together with the sea currents, they swim in search of delicious jellyfish and travel up to 17,000 km per year, and then return to lay their eggs on the very beach where they were born. Soaring birds are limited by the height of thermal currents, while waving birds can fly at high altitudes. That's why we rarely see many small migratory birds; they usually fly so high that they can't be seen from the ground.
