Unravelling the secrets of the world's highest flying goose
Some large bird species in Asia avoid the steep climb by migrating around the Himalayan mountains or by heading west towards the Caspian sea. Bar-headed geese, however, are known to migrate straight over the Himalayas, an energetic feat that has long been considered as one of the world’s highest altitude migrations. Using satellite tracking and archival heart rate logging, we describe the strategy used by bar-headed geese to carry out this impressive migration and some of the ways in which they may save energy. We also use physiological data to parameterize a model to estimate the maximum altitude to which a bar-headed goose might be able to fly in still conditions.
