The Arctic tern travels from the Arctic to the Antarctic each year, covering over 40,000 km round trip to breed in the summer months in the Arctic and winter in the Antarctic. Over its lifetime of about 26 years, an individual Arctic tern may travel over 1 million km migrating between its breeding and wintering grounds twice annually.

The Arctic tern travels the longest distance of any migratory bird: it
journeys from one pole to another two times a year, covering 40,000 km.
Over the course of its life, about 26 years, an Arctic tern can travel up
to 1 million kilometres.

This document discusses alligators, caimans, and their similarities and differences. It notes that alligators and caimans are reptiles in the order Crocodilia. The American alligator can grow up to 4 meters long and 360 kg, while the Chinese alligator is smaller at up to 2.1 meters. Alligators and caimans live in freshwater environments like marshes and rivers. They can move on land using two forms of locomotion and prey on smaller animals. Their skin and meat are used by humans. Alligators and caimans are distinguished from crocodiles by features like their snout shape and visible teeth when their mouth is closed. Caimans are also discussed, noting their endangered

Reptiles

vandanagiri1

Reptiles are cold-blooded vertebrates that breathe using their pulmonary system. They include turtles, tortoises, lizards, snakes, and crocodilians. Reptiles can be carnivorous, herbivorous, or omnivorous. Crocodiles live in both saltwater and freshwater and feed on fish, birds, and invertebrates. Alligators are large aquatic reptiles with scaly skin, four feet, and a sharp-toothed snout. Snakes range greatly in size and habitat but many hibernate in cooler climates.

This document provides information about 15 different animal species found in temperate forests: - White-tailed deer, squirrels, mallard ducks, black bears, foxes, bald eagles, turkeys, raccoons, beavers, cardinals, rabbits, muskrats, skunks, weasels are described along with some key facts about their physical characteristics, habitat, diet and behaviors. - These animals occupy a variety of niches in temperate forests and surrounding areas, with some being herbivores, carnivores or omnivores, and playing important roles in the forest ecosystem.

Polar bear

The polar bear is the largest land carnivore and apex predator of the Arctic. It lives in the middle and polar ice zones of the Northern Hemisphere. Polar bears have more elongated bodies than other bears, with well-developed legs adapted for both walking and long-distance swimming. They have small ears and tails to help conserve heat, and adults typically weigh between 400-600 kg for males and 175-300 kg for females.

Palaearctic region

The Palearctic region is one of the eight biogeographic realms of the Earth. It includes Europe, northern Africa, northern China, Russia, Japan, Iran, Afghanistan, and western Pakistan. The climate is mostly temperate, with both forested and open steppe lands. Zoologically, the region contains many families of mammals like rabbits, hedgehogs, and deer. It also has over 50 families of migratory birds but no parrots. Reptiles include turtles, tortoises, lizards and snakes. Amphibians prominently feature newts and salamanders. Fish include carps, salmon, and eels, with carp being dominant.

Mammoth

Mammoths were a genus of extinct elephant relatives that lived from 4.8 million to 4,500 years ago. They were well adapted to cold environments with long hair, small ears, and large size. The woolly mammoth survived the longest, until around 3,750 BC in Alaska and 1,650 BC on Wrangel Island. The causes of their extinction are debated but likely involved climate change and human hunting. In 2007, the remains of a one-month old mammoth were discovered frozen in permafrost in Russia.

Migratory birds face threats from habitat loss, hunting, and collisions with man-made structures. International cooperation is needed to protect birds that migrate across multiple countries. Migratory patterns are genetically programmed and cued by changes in day length, though navigation also involves sensing the earth's magnetic fields and using visual landmarks. Stopover sites between breeding and wintering areas are important but less protected than other areas. Conservation groups have worked to establish protected areas and regulations to help preserve migratory birds and their long-distance journeys.

Migratory birds are some of nature's most magnificent creatures that play important ecological, economic, and cultural roles. Neotropical migratory birds nest in North America and migrate south to Latin America and the Caribbean for winter. Over half of bird species nesting in the US are neotropical migrants. These include songbirds, waterfowl, birds of prey, shorebirds, and others. Migratory birds may be at risk due to lack of protection during nesting season or migration. The legislative definition of migratory birds includes species that annually migrate through parts of North America, Central America, South America, Asia, and beyond.

Students at DAV Public School in Khera Khurd, Delhi learned about migratory birds through a field visit to Yamuna Biodiversity Park. They collected data by filling survey forms and made blogs and PowerPoint presentations about different migratory birds. They included information on birds that migrate to and from India. Students also created cartoons of migratory birds that were displayed to teach others about these birds.

LSC-CyFair Academy for Lifelong Learning

This document provides information about common winter bird species seen in Houston backyards and summarizes key facts about bird migration. It discusses the typical migration distances and routes of different bird species in North America. The document explains that birds are triggered to migrate by decreasing daylight hours and hormonal changes, and notes that favorable winds and weather conditions influence when migration occurs. It describes some of the navigational techniques birds use to complete long migrations and identifies threats migrating birds face from human activities like habitat destruction and pollution.

Birds migrate for reasons such as finding more food, dispersing their young, avoiding predators, and seeking more favorable climates. They navigate using the sun, stars, and landmarks, and possibly a magnetic sense. Migration is studied using bird ringing where birds are caught, tagged, and released to track their movements. Migrating birds face challenges including harsh weather, lack of resources, and threats from other birds and humans. Activities to teach children about bird migration include making bird houses, reading books, bird watching, marking routes on maps, art projects, and learning about climate and predator risks birds encounter.

This document discusses the different features of birds including beaks, feet, and claws. It explains that birds have various beak shapes suited to their diets, such as short and hard beaks for seed-eating birds like sparrows and pigeons. Birds of prey like eagles and vultures have strong, curved beaks for tearing flesh. It also describes different claw and foot structures among birds related to tasks like perching, swimming, or wading in shallow water.
