The 2025 Osprey Project report has been published (in French only) in the March 2026 edition of the journal Nos Oiseaux<\/em>. Three males<\/a> from the Swiss reintroduction project returned to the Three-Lakes region in 2025. Arthur<\/em> came back to his Hagneck territory for the sixth year, although still didn\u2019t manage to retain a passing female. On the other hand, Olympe<\/em> and Racine<\/em> each paired with an unringed immature female. Bringing fish to the female, nest-building and mating were observed in their territories during two months in the summer.<\/p>\n

Concerning our females, Mouche<\/em> and her partner successfully produced two young again in Moselle (France), and Chronos<\/em> and her male Kepler<\/em> bred again in Baden-W\u00fcrttemberg (Germany) but failed, possibly due to disturbance by a Pine Marten. Pistache<\/em><\/a>, released at Bellechasse in 2018 but not seen again after she first left on migration, was discovered breeding with an unringed male in Marne (France), where the pair fledged two young.<\/p>\n

Three new nest platforms were built in the Three-Lakes region, and two \u201cOsprey Mornings<\/a>\u201d were held in June. The 2025 report can be downloaded here.<\/a><\/p>\n

\"Cover<\/a>The 2024 Osprey Project report has been published (in French only) in the March 2025 edition of the journal Nos Oiseaux<\/em>.\u00a0 At least three males from the Swiss reintroduction project (Arthur,<\/em>\u00a0Olympe<\/em> and Racine<\/em>) were confirmed back in the Three Lakes region in 2024, with a possible fourth (Flamme<\/em> ?) in the French department of Doubs. Two of our females again bred successfully: Mouche<\/em> produced two young in France (Moselle), while Chronos<\/em> fledged three chicks in Germany (Baden-W\u00fcrttemberg), along the Rhine River.<\/p>\n

An unringed female<\/a> spent much of the summer in the Three Lakes region, and received visits from all of our three territorial males. However, from her plumage she appeared to be probably only two years old, thus still too young to be interested in males.<\/p>\n

Two “Osprey Mornings<\/a>” were held in June 2024, as well as – for the first time – a more targeted \u201cmini-Osprey morning<\/a>\u201d in July. In addition, two new nest platforms were built in the Haut-Doubs, in neighbouring France.<\/p>\n

The 2023 Osprey Project report has been published in the March 2024 edition of the journal Nos Oiseaux<\/em>. 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<\/a> (Moselle), and the other two in Germany<\/a> (Baden-W\u00fcrttemberg). The discovery of Chronos<\/em> in Germany brings the total number of returnees from the reintroduction programme up to 11.<\/p>\n

Two unringed females were observed in male-occupied territories in 2023: one for two weeks in the spring at the Grande Cari\u00e7aie (Lake Neuch\u00e2tel), where she paired with Olympe<\/em> (F28) on a platform built by the project; the other during the summer in the Drugeon river basin (Haut-Doubs).

\"Cover<\/a>The 2022 Osprey Project report has been published in the March 2023 edition of the journal Nos Oiseaux. While only in French, this report outlines the highlights of last year. So far, two birds reintroduced each year between 2016 and 2020 are known to have returned: six males in Switzerland and one male and three females in neighbouring countries. As in 2021, Mouche<\/em><\/a> successfully fledged two chicks in France (Moselle), while Plume<\/em> bred again in Germany (Bavaria), but failed before the eggs hatched for unknown reasons. Rafale<\/em>, seen in 2021 in Germany, returned there once again but does not appear to have bred.<\/p>\n

Four males held territories in Switzerland: Taurus<\/em> for the fourth year, Arthur<\/em> for the third, as well as Olympe<\/em><\/a> and Racine<\/em><\/a> which both came back for the first time. The 2021 mystery bird in the Haut-Doubs turned out to be Flamme<\/em><\/a>, living on the French side of the border and seen fishing in Switzerland. Radar<\/em>, released in 2019 and observed twice in 2021 (in Switzerland and in Belgium), was not seen again last year. However, during one of our \u201cOsprey Mornings<\/a>\u201d six different individuals were spotted, so he may have been one the birds for which we could not see if it was ringed.<\/p>\n

The German female ringed AB13 who had paired with Taurus<\/em> in 2022 unfortunately did not return, but another (unringed) female spent part of the summer at the Lake of Neuch\u00e2tel where she was seen displaying with Olympe<\/em>.
