2023 Project Report

Olympe F28 and unringed female mating on Osprey platform Lake of Neuchâtel, Switzerland

The 2023 Osprey Project report has been published in the March 2024 edition of the journal Nos Oiseaux.  While only in French, this report outlines the highlights of last year. At least three males from the Swiss reintroduction project were confirmed back in the Three Lakes region in 2023, and a very likely fourth in the French department of Doubs. Two females released in Bellechasse bred successfully, one producing three young in France (Moselle), and the other two in Germany (Baden-Württemberg). The discovery of Chronos in Germany brings the total number of returnees from the reintroduction programme up to 11.

Two unringed females were observed in male-occupied territories in 2023: one for two weeks in the spring at the Grande Cariçaie (Lake Neuchâtel), where she paired with Olympe (F28) on a platform built by the project (see photo above); the other during the summer in the Drugeon river basin (Haut-Doubs).

As in previous years, two “Osprey Mornings” were organised in 2023. In view of their success, two are scheduled again this year, on Sunday June 2 and 23. Observation points will be mainly in the Three Lakes region, but also in the Drugeon, Doubs and Aare river basins. Anyone  interested in participating in one or both of these mornings can sign up here, or directly to wendy.strahm@gmail.com.
