The Rüppell's vulture sits firmly at the peak of high-altitude nesting mastery. These birds have been recorded at a staggering altitude of 11,300 meters (approx. 37,000 feet), colliding with a commercial aircraft—a height that surpasses the cruising altitude of most jetliners and dwarfs the summit of Mount Everest (8,848 meters).

Key Highlights:

• Aerodynamic Marvels: While most birds would succumb to hypoxia in the thin, sub-zero air of the stratosphere, Rüppell's vultures have evolved specialized hemoglobin with an extraordinary affinity for oxygen, allowing them to function where air pressure is less than a quarter of that at sea level.
• Survival Extremes: These 'masters of the sky' are not just record-holders for altitude; they are biological pioneers, pushing the absolute physical boundaries of avian physiology and flight.
