Bar-headed geese accomplish the extraordinary feat of migrating over the Himalayan mountain range twice a year, flying between their wintering grounds in southern Asia to their breeding grounds in the central Asian highlands. These birds have even been spotted over the summit of Mt. Everest, where oxygen levels are only about one-third that at sea level.
In order to better understand the exceptional physiological capability of bar-headed geese, Dr. Jessica Meir of the University of British Columbia (UBC) embarked upon a study with the goal of flying bar-headed geese in a wind tunnel, while monitoring various aspects of their physiology.

Meir traveled to the Sylvan Heights Waterfowl Park in North Carolina to seek the bar-headed geese for her study, arriving just in time for the hatching of this year's bar-head recruits. Because she was the first person or thing that the goslings set eyes upon after they were born, the imprinting process was set in motion and Meir began her role as "Mother Goose."
Over the last seven months, Meir has spent her days with the gaggle, bonding with them and taking them on walks and outings. And when the birds began flying, she began leading flight training sessions on a scooter with a bird at her side, at speeds ranging from 20 to 35 mph.
It is hard to miss the excitement in Meir's eyes as she cruises down the road on her scooter, the wingtip of one of her goslings brushing her shoulder at times, as she stares into the eye of this magnificent bird in the midst of flight, just inches away from her.
When not busy with the flock, Meir is in the lab preparing equipment for the flight experiments, scheduled to begin soon in UBC's wind tunnel. This work, funded by a National Science Foundation International Research Fellowship Program grant, will be the first time physiological measurements will be made on this species while flying under conditions of low oxygen, like those experienced during their migration.
