    • Abstract:
      The article focuses on a remarkable discovery of a mummified Sand Martin (Hirondelle de rivage Riparia riparia) found at an exceptionally high altitude of 3400 meters on the Mellichgletscher in Täsch, Switzerland, setting a new altitude record for this species in the country. Topics discussed include the description of the specimen, its identification, dating, and preservation, as well as an exploration of the factors that may have contributed to the disappearance of the bird's feathers.
