Abstract
New breeding records of Dotterel Charadrius morinellus in the Grisons. The Dotterel is threatened of extinction in the Alps due to its small population size. The main breeding area lies in Austria with a maximum of ten breeding pairs since 2003. In Switzerland, only two breeding records in the Grisons in 1965 and 1998 were known until recently. In 2012 and 2013, three more broods in the Grisons at an altitude between 2600 and 2770 m a.s.l. were recorded. The late timing of two broods was remarkable. The chicks, which were just a few days old, were discovered on 1 and 10 August, respectively. Therefore the eggs were laid in the first ten days of July. This is almost a month later than in 1965 and 1998, when eggs were laid in the first half of June. In the other breeding record a juvenile, just or almost fledged, was discovered on 18 July. Egg laying started thus around the end of May. With the advice to find the Dotterel given at the end, it is hopefully possible to discover more broods in future. It is recommended to check potential areas twice around 20 June and 10 July.
