1 Migration

2 What is migration? Migration - the regular movement of birds and other creatures from one part of the world to another and back Migration is usually seasonal Mammals, fish, reptiles, amphibians, insects, crustaceans and birds migrate Migration is a form of adaptation. Animals migrate to survive The trigger for the migration may be local climate or season change local availability of food, for mating reasons Learning about migration is one of the best ways to understand the risks that birds and other animals must take in their daily lives

3 World distances Write down the distances as they appear on the map
London to Edinburgh 350 miles km Cairo to Ulaanbaatar 4,000 miles 6,500 km Madrid to Paris 660 miles km Cape Town to Cairo 4,500 miles 7,200 km

4 The Humpback Whale The humpback whale can travel 16,000 miles a year
That is the greatest migration than any other mammal on Earth Each species of humpback whale travels to warmer tropical waters during the winter months to mate and give birth Then they swim to the rich colder waters of the Arctic or Antarctic to feed for the summer

5 Migratory animals The leatherback turtles travel across the Pacific Ocean between Indonesia and the U.S. An incredible distance of more than 12,000 miles in 647 days Females mate very 2 or 3 years One of their most impressive feats is the ability to navigate back the beach where they were born to spawn

6 Africa’s Wildebeest Africa's wildebeest herds travel annually by the millions in search of greener pastures More than 1.5 million wildebeest migrate in an enormous loop every year The wildebeest do not travel alone. As many as 200,000 zebra and 500,000 gazelles also make the journey Followed by some of the Africa’s top predators.

7 Birds About 1,800 of the world's bird species are migratory.
The tiny Arctic tern undertakes nature's longest migration, flying 43,000 miles annually between the Arctic and Antarctic. Starting in August and September, the Arctic tern will head away from Greenland with the intention of getting to the Weddell Sea, on the shores of Antarctica. It will spend about four or five months in the deep south before heading back to the far north, arriving home in May or June

8 Satellite Telemetry Biologists and researchers use Satellite Telemetry to track migration An object on earth can be tracked using satellites in space There are roughly 2,250 satellites orbiting the Earth Sent to falcon research team

9 Satellite Telemetry – how does it work?
The PTT sends digital codes to an orbiting satellite The researchers can create an online maps showing where the Falcon has been Data is sent to the researchers who can access the information through their computer. The satellite re-transmits the data to a receiving station on earth Researchers attach a Platform Terminal Transmitter (PTT) to the back of the Falcon
