Top 10 Animals in Natural Migration
Whether through the magnetic perception, solar or lunar orientation, landmarks, smell, echolocation, or any other method, many creatures of the earth love to travel. Our planet is filled with overlapping migration patterns that form the fabric of the natural systems of the Earth. Whether by biology that is beyond our perception, movement patterns transmitted across generations (such as elephants), or despair at the decline of habitats, animals are always moving. This list includes fish, birds, mammals and insects that have their unique brand Wanderlust great.
10. Gray Whales
Any number of whales could be placed on the list as highly migratory species. Our oceans are intertwined with corridors that whales use to find calm waters to birth their calves or cold water to consume their share of krill. The gray whale is the first example of how these marine mammals nomadic life. Hunted to near extinction in the early 20th century (and disappeared from the European side), these creatures have made a comeback in the North Pacific Ocean. Each fall, a group of these whales embark on a journey of 3-4 months starting in the Chukchi Sea and ends with the pilgrims warm waters of Mexico. As they are often hunted by orcas, these gentle giants roam along their best. The migration of the Pacific gray whale is highly documented and has become a great source of ecotourism.
9. Flying Foxes
Australia is home to four distinct types of foxes (fruit bats). These bats may be sensitive to extreme heat, they try to avoid as best they can. Their sensitivity to heat stress (especially in gray-headed flying foxes) will become another problem that the climate of the planet continues to warm. Their migration is driven by the need to flowering plants and nectar they contain. So it is that they require a wide range of operating effectively, something that becomes more difficult to find due to deforestation and agriculture. They travel to and from a variety of habitats such as wetlands, forests and other forest types. The bats continue to share similar fates down as the iconic koala, since both animals are turning to the eucalyptus trees as the main source of food.
8. Pacific Walrus
Walruses like to spend part of their year on the ice and their summers on rocky terrain near the sea during freezing their usual ice becomes too impenetrable for good fishing. This cycle will always lead to migration to the indeterminate scale. Walruses can find something suitable in any way. Pacific walruses tend to make an epic journey from the Bering Sea through the Bering Strait and the ice of the Chukchi Sea cold and vice versa. Females and calves are more migratory than the big bulls, and many calves are farrowed during the trip to the North. These animals were hunted to extinction many times, but have a joint protection of the United States and Russia, one of the few things we can agree.
It has been well documented that many marine species of fish live a migratory life. Often, these are the fish that are heavily targeted by commercial fisheries. The reason is the lack of international law concerning the harvesting of fish that migrate across the ocean gyre. And types of tuna fish as it moves around the entire ocean and so through a multitude of nations and waters. A country think that if they do not harvest the fish then someone else will. The end result is a massive harvest (and the extinction of several) types of migratory fish species. More than half of tuna species are threatened with extinction in the near future. However, in many markets around the world, you can always buy them relatively cheap meat. If we want to continue to have our tuna sushi, we’d better start to consider more sustainable options in fishing.
Regardless of the ocean of origin, migration of salmon are notoriously dramatic. Let the fish of the sea and enter freshwater rivers, swimming upstream, and dodge predators at every turn. Perhaps the most widely publicized obstacles of this trip are the obstacles that grizzly bear has set up along the way. These stocky mammals have to align the tops of many waterfalls along the way and sit down to fish. Salmon is the strength to make a leap of faith that ends either in a new batch of cold water source or a cracking sound terrifying made by brewing their bone mass bear jaws. For all the hundreds of fish that make it past the fishermen fur, we obtain nets. The task may seem suicidal, and that’s because it is. After all these efforts, even if a salmon goes where it wants to go, then the fish just opens wide mouth like a submarine cry companions going belly up, and dies. Their rotting carcasses are left to feed the ecosystem where they came from.
5. Army Ants
For many small and large animals their lives is a migration. Perhaps one of the most distinct examples of this nomadic lifestyle can be found in the continents of Africa and South America. There are over 200 species of army ants there, and these little buggers offer perhaps the best example of the mentality of swarm, is a lot of individuals acting as one, in the animal kingdom. Their life is so nomadic that they do not even have to build housing. Instead, they come together to form their own structure called a bivouac. The structure of the breath of life becomes a temporary plant reproduction where parts of their prey are brought to be consumed. Impressive, these ants can dismember prey many times their own size through teamwork and tactics swarm. Their strong jaws can reduce or tarantulas croquettes and pieces in no time.
4. Sandhill Cranes
Hundreds of thousands of cranes moving north-eastern Siberia to the U.S. Midwest and South each year. They travel in herds of more than ten thousand bird size and dip in states like New Mexico and Arizona. They glide through heat sinks, or hot air from areas of land as a result of the uneven solar radiation, to save energy in the long term. If you look at a flock of cranes, then you could even make the outline of a thermal column they use. This species is estimated at millions of years. Their migration to the heart of America is relatively new, however. Migration is the result of adapting to the ever-growing presence of humans around the world. At the southern end of their journey, they find their main source of food: the remains left by discarded mechanical harvesting farms. Farmers appreciate the new support for these ancient creatures, as they help to clean the place.
Perhaps no animal is best known for his prowess as the wildebeest migration. The timing of their travel is irregular, but are thought to follow the trends of average rainfall and foliage growth that accompanies it. Wildebeest often travel with zebra use as bait for additional crocodile when they swarm crossings perilous rivers. They also have a special knowledge of the languages of other animals, and so meet the many alarm calls. Even with their incredible ability to come together and work through a swarm mentality, these guys always end up providing lunch at the door of predators keystone of Africa. Vultures also follow this migration as an important source of food, and so are inevitably entangled with the wildebeest. If the number of wildebeest run out through famine or natural poaching, vultures also suffer.
2. Monarch Butterflies
Monarchs are quite common in many states in the north-eastern United States, and the same range as far north as Canada. They often announce the arrival of warm weather and dazzle the eye during the hot days. What we may not realize, or at least understand the magnitude of it is that creates these beautiful travel more than 5,000 miles (to and from) each year. When they notice that winter is coming, these butterflies luggage and head to Mexico and parts of the United States that border. The warm temperature throughout the year reflects these creatures until they are ready to head north again. The back and forth dynamic is simply because, although monarchs can not survive the winter in the north, they need flowers larvae that spring break provides. Pontes insects are not as common or expected in the hot corners of overwintering areas.
1. Arctic Terns
The holder of the longest migration from start to finish, the Arctic tern is a tough guy who likes to travel winged. They are both in the North and South polar regions and enjoy the summer at each location. When the winter winds begin to blow, these wanderlusts luggage and head to literally the opposite of the world. If you do the math, they traveled more than 40,000 miles per year. With each bird healthy living around 30 years is more than 1.2 million miles flown on each life. Like George Clooney, the Arctic tern spends much of his life in the air. For food, the feathers will often commuters cup of other birds in the air, forcing them to abandon their prey. They stop their migration habits nest every one to three years.
