Swiss altitude record for a Sand Martin Riparia riparia and remarks on the conservation of the specimen. On July 18, 2002, the mummy of a Bank Swallow was found on the ice of the Mellichgletscher (Täsch VS), at the foot of the Feekopf, at an altitude of around 3400 m. Carbon 14 dating suggests that the bird died after 1955 at the latest. Different...

We tried to assess how many species of living organisms (except viruses) can be found in Lake Geneva, using ancient litterature as well as recent assessments. We find 1167 pluricellular species (996 animals, 171 plants) and 585 unicellular species, that is in total 1752 species.

With 18’562 egg sets, the egg collection of the Natural history Museum of Geneva (MHNG) lies in the ten biggest in Europe. An important step was taken in 2011 with the purchase of Werner Haller’s oological collection, whose housing in calibrated boxes facilitated digitization. This collection represents about half of the actual egg collection in Ge...

A rare very dark morph juvenile Long-tailed Skua was found dead in Lake Geneva on 5th October 2016. The absence of white markings typical of the juvenile plumage of the species (especially on rump and undertail coverts) made the identification difficult. Measurements and colour of bare parts could confirm the identification and the fact that the da...
