The record-breaking chicken that flew from Alaska to Australia with out stopping
Staring on the sky, have you ever ever puzzled the place all of the birds fly to?
Only a few birds dwell their complete life in the identical location; most of them take to the air with a purpose to uncover a dependable supply of meals, to start out a household, or to outlive the altering seasons.
While some migrations are quick, others journey throughout huge distances. For migrating birds, a missed flip can show to be deadly as a result of they spend a number of weeks flying over oceans and continents from one finish of the planet to a different.
Nonetheless, in 2022, one juvenile chicken efficiently earned a spot in historical past with its surprising flip.
A bar-tailed godwit (Limosa lapponica), recognized by its tag quantity “234684”, flew 13,560 kilometres (8,435 miles) from Alaska to the Australian state of Tasmania with out stopping for meals or relaxation, breaking the file for the longest continuous migration by a chicken.
The gap coated is equal to 2 and a half journeys between London and New York, or roughly one-third of the planet’s full circumference.
In keeping with the 5G satellite tv for pc tag hooked up to its decrease again, the epic journey began on 13 October 2022 and continued for 11 days and one hour with out the chicken touchdown as soon as.
This isn’t the primary time that bar-tailed godwits have hit the headlines for his or her marathon migrations. This five-month-old chicken smashed the earlier file, set by one other of its species in 2020, by over 350 km (217 miles). That godwit in flip had out-flown one other that flew for 11,500 kilometres (932 miles) in 2007.
Bar-tailed godwits aren’t the one long-haul travellers within the chicken world. Arctic terns (Sterna paradisaea) can recurrently fly even better distances over the course of a yr.
Certainly, factoring in a spherical journey from their breeding websites north of the Arctic Circle to Antarctica and again, these industrious seabirds would possibly cowl as a lot as 80,000 km (50,000 mi), making theirs the longest chicken migration general. Nonetheless, the important thing distinction is that they often contact down throughout their superlative voyages.
Though most birds migrate many miles in quest of meals and heat, some have a capability to remodel bodily to fulfill environmental situations.
They’ll drastically alter their our bodies and metabolism by shrinking the dimensions of their inner organs, shortly gaining weight and burning via fats reserves, barely sleeping, and lots of different superpower-like qualities apart from.
Godwits, significantly, make place for energy-rich fat by absorbing 25% of the tissue that varieties their digestive tract, liver and kidneys. That is made attainable via a organic course of often called autophagy (“self-eating”), a mechanism that permits the physique to recycle elements of itself as and when required.
Godwits may make their hearts and chest muscle tissue larger mid-flight to offer extra vitality and oxygen to those areas.
These extraordinary expertise do have some drawbacks, although. The bodily adjustments make godwits extra prone to each pure and human-made hazards as a result of they lack the vitality wanted to fly lengthy distances.

Our new record-breaking godwit was lucky to outlive its trek throughout the big Pacific Ocean and quite a few islands, together with New Caledonia and Vanuatu, the place it appeared to have handed up the prospect to refuel.
Birdlife Tasmania convenor Eric Woehler stated the chicken in all probability misplaced “half or extra of its physique weight throughout steady day and evening flight.”
“Quick-tailed shearwaters and mutton birds can land on the water and feed. If a godwit lands on water, it’s useless. It doesn’t have the webbing in its ft, it has no means of getting off. So if it falls onto the ocean’s floor from exhaustion, or if dangerous climate forces it to land, that’s the tip.”
Usually, godwits migrate to New Zealand, however this one made a pointy 90-degree flip and landed on the shores of Ansons Bay in japanese Tasmania, Australia.
Dr Woehler summarized that this “improper flip” elevated the beforehand assumed “flight capability” of the species, which poses the query: may one other godwit sooner or later fly even farther with out stopping?
Consultants are hoping that this file flight will spotlight the significance of higher understanding animal migrations, the navigational methods employed by these birds, and what will be completed to protect the environments the place they do lastly cease to feed.
After making such a staggering journey as this, who may deny godwits solely the most effective five-star amenities once they contact down?
