       Just for the record, here are some altitudes:
 "Bar-headed Geese are known to cross the Himalayas at 29,500 feet (9,000 m). 
The world record holder is a Ruppellâs Griffon Vulture seen at 37,000 feet 
(11,300 m.) A Mallard, which struck an airplane at 21,000 feet (6,400 m), 
holds the record for the highest documented flight altitude for a bird in 
North America."
