Which bird flies the highest in the sky?

does this mean that this bird would also fly the furthest distance without stopping?
Answers:
The Bar-headed Goose may be the highest-flying migrant. These geese have been seen flying over the Himalaya at an elevation of 28,000 feet.
vultures
I think, I think it is a swallow tailed hawk. I might be wrong but not too long ago I read something on line about this bird and if I recall right it mentioned that it flies the highest.
The one furthest from the ground...

..and no, not necessarily!

i'd have to say it would either be a kind of goose, while on migration, or the albatross.
Not absolutely positive, but the highest a bird nests on earth i believe is the Condor in the Andes (which everyone knows are at the end of your armies), so technically having an head start from so high up that could be the one. And as for furthest i believe the Albatross wins that one.
the greatest altitude documented as of the mid 1980's was a Ruppell's griffon, an African vulture, struck by an airliner at 37,000 feet. Another vulture, a lammergeyer was seen over "its mountain home" at 25,000 feet over Mt. Everest; alpine choughs have been recorded nesting at 27,000 feet on Mt. Everest. A mallard was struck by an airliner at 21,000 feet over Nevada. Records of smaller birds, also from hitting airplanes, are mostly from 7,000 to 12,000 feet. So I would say The Ruppel's Vulture is the bird that has flown highest.

Bar-headed geese are probably the birds that fly highest on a regular basis. They breed in Tibet and winter in India, so they have to fly over 18,000 feet to get through the Himalayan Mountains. The bar-headed geese have been seen flying at 28,000 feet high. Demoiselle cranes, godwits, and curlew have also been seen flying around Mount Everest at 20,000 feet. The Himalayan snowcock nests at those high altitudes too. Those are some high-flying birds!
I have recently been watching a TV documentary - The Planet. In one episode, it documented a flock of thousands of migrating cranes - not sure if they were cranes or some other birds from China. The birds were on their expedition to cross Himalayas into warmer regions of India. Twice or thrice their attempts was thwarted by fast opposing winds at the top of the mountain and thin oxygen levels at high altitude but eventually they made it over to the other side. This, I believe, could be the highest that any bird would ever have felt a need to ascend to.

highest flying bird: Ruppell's griffon vulture at 11,274 in (7 mi)
The Bar-headed Goose can fly at 30,000 feet. It actually flies over the Himalayan mountains. I don't believe it would mean it can fly the furthest distance without stopping though. That honor could belong to the arctic tern which migrates between Antarctica and the Arctic Circle. But the Ruppell's Vulture seems to be the winner according to Guinness Book of World Records website at 37,000 feet. It flies so high so it can expand its view of the landscape to better detect any available carrion or other vultures that have located carrion, presumably.
The Ruppell's griffon, an African vulture, was struck by an airliner at 37,000 feet (11,300 metres).
