Geese aren't the main winged animals that relocate. Cold terns make one of the longest trips of all. These seabirds spend the late spring in the Ice, where there are a lot of little fish to eat. The winged creatures lay eggs and back their young here. As winter approaches, the flying creatures fly south. They fly the distance to the Antarctic, where it's mid year and they can discover a lot of fish. Their round-trip travel takes them around a half year, three months every way! It's around 20,000 miles (35,000 kilometers) in length. Numerous sorts of ducks, falcons, larks, and different feathered creatures additionally relocate.

BATS AND BUTTERFLIES

Other flying animals other than winged creatures move, as well. A few sorts of bats relocate. Ruler butterflies make astounding excursions.

Every fall, a huge number of ruler butterflies in North America relocate. Rulers from west of the Rough Mountains travel to California. Rulers east of the Rockies travel to Mexico.

It's a separation of around 1,300 miles (2,000 kilometers). After the eggs are laid, the grown-up turtles come back to Brazil's seaside waters.
