There are many spectacular issues about birds. Some soar for miles with out ever flapping their wings; some reside for over half a century; and a few are literal rainbows. But whenever you take a look at a hen gliding excessive up within the distance, have you ever ever puzzled simply how excessive they’ll go?
The species that holds the document for the best flight of any hen is the Rüppell’s vulture (Gyps rueppellii).
In 1973, one Rüppell’s vulture struck a industrial plane 11,300 meters (37,000 toes) above Côte d’Ivoire in West Africa. While one in all its engines was broken, the aircraft managed a profitable touchdown. The hen was sadly not so fortunate. All that remained of it had been five complete and 15 partial feathers – sufficient for a optimistic ID of the species, and for this unbelievable feat to be confirmed, however most likely scant consolation to any pals of the deceased.
We jest, however sadly this hen most likely did have pals, and perhaps even a big different. They’re very social and are thought to type monogamous pair bonds, with each mother and father serving to to maintain any chicks for the primary 150 days of their lives.
Native to a area of Africa referred to as the Sahel, which spans a swathe of land between the Sahara and the Sudanian savanna, the vulture’s home vary covers a number of nations together with Zimbabwe, Senegal, and Ethiopia. From time to time, they’ve additionally popped up throughout the Mediterranean in Spain.
Unfortunately, although, these sorts of visits would possibly change into extra of a rarity sooner or later, because the Rüppell’s vulture has been categorised by the IUCN Red List as Critically Endangered. Like many comparable African birds, they’re threatened by habitat loss, searching, and decreased availability of their sole meals supply, carrion.
There’s additionally an enormous downside with poisoning, particularly in East Africa. This has largely been from a pesticide referred to as carbofuran, however the charity BirdLife International additionally highlights the function of the drug diclofenac. This anti-inflammatory can be utilized in veterinary remedy however is deadly to Rüppell’s vultures in the event that they ingest the carcasses of animals which have been dosed with it. Surprising, when you think about that they’ll happily chow down on meat that’s infested with anthrax and botulism.
If you ever are fortunate sufficient to identify a Rüppell’s vulture within the flesh, it’s a sight you gained’t neglect in a rush. These majestic birds attain heights of almost a meter (33-38 inches) and have a particular feather-free head – Animalia writes that this adaptation stems from their tendency to stay their entire heads inside their prey whereas they feast upon it.

Their highly effective wings span over 2 meters (7-8 toes), however they use them sparingly in flight. Even once they’re not inflicting a headache for industrial pilots, Rüppell’s vultures usually attain spectacular altitudes, making the most of robust thermals as they soar over the bottom and scan for his or her prey.
It’s fairly doable, even possible, that the 1973 occasion was an anomaly. There are the reason why you don’t usually see birds flying alongside passenger planes at cruising altitude, most of them having to do with oxygen.
Other contenders within the altitude stakes embrace the widespread crane (Grus grus), which has been recorded at 10,000 meters (32,800 toes) because it evades eagles within the Himalayas, and the bar-headed goose (Anser indicus), which has been noticed at a most peak of seven,300 meters (24,000 toes) and has supersized lungs to deal with the dearth of oxygen.
Still, BBC Wildlife studies that even with fashionable monitoring know-how, we’ve no document of one other hen coming near the Rüppell’s vulture’s document, so its crown seems to be secure for now.
