Females in the spotlight

Female Osprey Pistache F11 at her nest in the Marne, by Alain Balthazard

After Plume (F02) in north-eastern Bavaria (Germany) in 2021, Mouche (PS4) in Moselle (France) since 2021, and Chronos (ex-PS9) in Baden-Württemberg (Germany) since 2024, we have received the great news that another one of our females, Pistache (F11) was recently discovered breeding in the French department of the Marne (photo above by Alain Balthazard). Seen for the first time after nearly seven years on March 11 in the department of the Meuse, she has partnered with an unringed male and is nesting on an electricity pylon, approximately 270km away from the Bellechasse release site. The nest is about 6km away from the only other pair known in the department, and observers from the LPO and others are monitoring them carefully.

At the same time in Switzerland, one of our territorial males paired with an unringed female last month. All seemed to be going for the best, with the male bringing regular offerings of fish, fixing up the nest chosen by the female, and mating often. Until a week later, when the female suddenly disappeared. However, another unringed female then joined him around mid-May. While it is now a bit late for them to breed this year, we are watching the area closely.

The two Osprey Mornings scheduled on Sunday June 15 and June 29 will hopefully provide new insights and perhaps even some birds that haven’t been found yet. As usual, various observation points will be in the Three Lakes region, and we will also try to focus more this year on favourable sites in the Drugeon, Doubs and Aar river basins. If you have already signed up for one or both mornings no need to recontact us, but if you haven’t yet and are interested in participating, please contact us here.
