Long Distance Migrations

No Fear, No Limits - Bar-headed Goose Anser indicus

These hardy geese have mastered the art of high-altitude flight. Despite their limited ability to soar for extended periods, they consistently reach greater heights than many other migratory birds. On their journeys from breeding grounds in Mongolia, Tibet, and northern China to wintering sites in India, they traverse the Himalayas at altitudes of up to 7,000 meters, with only a fraction of the oxygen available at sea level. Scientists believe they conserve energy by flying close to the mountains and at night, but the genetic basis for their extraordinary tolerance remains a mystery. Some scientists who raised a gaggle of geese as their own 'children' have discovered the secret behind their high-altitude success, which can see them soar at  29,500ft, lies in the ability to chill their blood to lower temperatures and preserve energy. Although their population is declining, their vast range means they are currently considered "Least Concern" by BirdLife International.

Racing Against the Wind - Great Snipe Gallinago media 

The Peregrine Falcon is a total speed demon, hitting speeds of up to 390 km/h when it dives for prey. But don't let that fool you – it's not a marathon runner!

The Great Snipe, believe it or not, is the champ of long-haul flights. Who would've thought this little chubby bird could fly so far and so fast? Without any help from the wind, this bird has been clocked at 97 km/h over a distance of 6,800 km. That's like flying from Australia to the UK without stopping! And to make it even more impressive, it loses half its weight during this crazy journey.

Unfortunately, the Great Snipe is in trouble. Habitat loss due to farming and wetland destruction is putting it at risk.

Always on the go - Bar-tailed Godwit Limosa lapponica 

Imagine flying for nine days straight without a wink of sleep or a bite to eat. That's the life of a Bar-tailed Godwit! These birds are champs, flying from Alaska all the way to New Zealand in one go. It's the longest non-stop flight of any bird, and it's totally mind-blowing.

Even though they're super tough, some Bar-tailed Godwits are struggling. Those that fly the East Asian-Australasian route are having a rough time because their homes are disappearing. So, they're on the endangered list.

But there's hope! BirdLife is working with governments to protect their stopover spots and keep their homes safe. Even though these birds are tough as nails, they still need a place to rest and refuel. Let's give them a break.

The Long Haul - Red Knot Calidris canutus 

Even though the Red Knot is only a small bird with a wingspan of 20 inches, some of them fly an incredible 15,000 kilometers every year! They travel all the way from the southern coasts of Chile and Argentina up to the Canadian Arctic Archipelago. Unfortunately, human activities are making this journey much harder for the Red Knot. Coastal development and overfishing of horseshoe crabs, whose eggs are a crucial food source, have led to the Atlantic subspecies of the Red Knot, the Rufa Red Knot, being listed as threatened in 2014.

Penguin Pilgrimage - Adélie Penguin Pygoscelis adeliae

Who says you need wings to migrate? Penguins, these flightless birds, trek thousands of miles every year! The Adélie Penguin, for example, walks around 13,000 kilometers (8,077 miles) to find the sun in Antarctica.

It's a tough life. In winter, the sun doesn't shine where they live, so they keep walking to the edge of the ice. Luckily, the ice gets bigger in winter, so they can always find a spot to chill. When spring comes, they stay near the edge as the ice melts.

Even though climate change is making things harder for them, Adélie penguin populations are actually growing, especially in East Antarctica. It's great news! But we still need to be careful about how we treat our planet to help these amazing creatures."

Short-tailed Shearwater Ardenna tenuirostris, or Tasmanian Muttonbird, is a pretty amazing seabird with a crazy migration. Every year, these birds take a long flight from their homes in Tasmania and southern Australia all the way to Kamchatka in Russia, then on to the Aleutian Islands in Alaska, and finally back home around the western coast of North America.

They’re built for soaring over the ocean, so they can fly for ages without getting tired. Even though they travel thousands of miles, they always know how to find their way back to the same burrows year after year. While their numbers have gone down in some places, there are still millions of these birds flying around Australian waters, making them the most common seabird you’ll see there.

A Global Traveler: The Arctic Tern's Sterna paradisaea Migratory Patterns

No discussion of bird migration is complete without acknowledging the extraordinary feats of the Arctic Tern. Imagine flying 90,000 kilometers every year! This medium-sized bird holds the record for the longest known migration in the animal kingdom. Each year, it travels an astonishing 90,000 kilometers (55,923 miles) from pole to pole, journeying from Greenland in the North to the Weddell Sea in the South. This little bird is a real world traveler, flying from the chilly Arctic to the icy Antarctic and back.

With a lifespan of up to 30 years,  that's a lot of air miles to rack up. An Arctic Tern can accumulate a lifetime journey equivalent to more than three round trips to the moon. Yes you read that right. It is like taking a non-stop flight to the moon... three times! This incredible feat of endurance and navigation is inspirational – it's a symbol of how birds can travel the globe and connect us all.
