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
World distances
Write down the distances as they appear on the map
Cape Town to Cairo
4,500 miles 7,200 km
Cairo to Ulaanbaatar
4,000 miles 6,500 km
London
to
Edinburgh
350 miles 550 km
Madrid to Paris
660
miles
1000
km
The Humpback Whale
The humpback whale can travel 16,000 miles a yearThat 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
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 daysFemales mate very 2 or 3 yearsOne of their most impressive feats is the ability to navigate back the beach where they were born to spawn
Africa’s Wildebeest
Africa's wildebeest herds travel annually by the millions in search of greener pasturesMore than 1.5 million wildebeest migrate in an enormous loop every yearThe wildebeest do not travel alone. As many as 200,000 zebra and 500,000 gazelles also make the journeyFollowed by some of the Africa’s top predators.
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
Satellite Telemetry
Biologists and researchers use
Satellite Telemetry to track migrationAn object on earth can be tracked using satellites in spaceThere are roughly 2,250 satellites orbiting the Earth
Sent to falcon research team
Satellite Telemetry – how does it work?
Researchers attach
a Platform Terminal Transmitter (PTT) to the back of the Falcon
The PTT sends
digital codes to
an orbiting satellite
The satellite re-transmits the data to a receiving station on earth
Data is sent to the
researchers who can access the information through their computer.
The researchers can create an online maps showing where the Falcon has been
