Posted by External 70 days ago General — A study of the migratory biology of bar-headed geese, during their high altitude flights across the Tibetan plateau and Himalayan Mountains, has revealed how these birds cope with flying in the relatively low-density mountain atmosphere. The study shows that the geese perform a 'roller coaster' ride through the mountains, tracking the underlying terrain even if this means repeatedly shedding hard Read More
