The bar- headed goose, for instance, can fly for days at Himalayan heights without taking a break.

I've almost broke my heart in trying to convince that thick- headed goose that he can't set the table properly.

Snow partridges are found at elevations of 18,600 feet, but the bar- headed goose goes much higher than that.

The only waterfowl known to have flown higher is the bar- headed goose, which reaches more than 7,000 metres.
