Water hemmoraging from Natura2000 peatbog in Belgium's Haute fagne. Deep drainge, bad for biodiversity, floods, summer droughts. For the sake of uneconomic spruce plantations.

Aren't Epipactis the best looking orchids? With all their shades of... green 🤩 An excursion with the #Naturalistesbelges in southern Belgium under the guidance of Pierre Devillers delivered its two targets: Epipactis muelleri and Gymnadenia odoratissima, only known from a handful of sites

First breeding of greater black-backed gull for Belgium in the Zeebrugge front harbor gull colony 👇
Een nieuwe broedvogel voor België: de eerste kuikens van de grote mantelmeeuw ooit in België geboren! Het was een verrassing van formaat dat er dit jaar een koppeltje grote mantelmeeuwen broedde tussen de kleine mantelmeeuwen en zilvermeeuwen.

The 4th Lesser Kestrel for Belgium—an adult male (!)—is currently feasting on crickets on an airfield managed by the administration and @natuurpunt.bsky.social, kindly opened to birders for the occasion. The 1st twitchable, a few days after our 1st twitchable Blue-cheeked Bee-eater. #BirdingBelgium

The 2nd Blue-cheeked Bee-eater for Belgium put on a show last Sunday, but left early in the afternoon. It was the 1st twitchable for the country, as the previous one was a flyover. Symens & Ducastel discuss the 2017 record, its ssp. id and wider European context: www.natuurpunt.be/sites/defaul...

Ardea alba melanorhynchos—with black legs, a dagger-shaped bill, a light loral area, a long gape, and a wide 'moustache' reaching the tomium. I can finally put a name on this Great Egret seen on Santiago (Cape Verde) in 02/2022. Great paper in DB and superb illustrations by Sébastien Reeber! Thanks!

« La cellule Déméter menace les militants animalistes et environnementalistes, ainsi que les libertés associatives »
Créée en 2019 au sein de la gendarmerie, cette cellule est notamment chargée de collecter des informations sur les « actions de nature idéologique » remettant en cause le modèle agricole. Dans une tribune au « Monde », un collectif de quelque 120 signataires s’inquiète des méthodes de cette cellule et demande sa dissolution.

Worrying news from the heartland of Lesser Spotted Woodpeckers in Britain. Meanwhile, in #Wales the number of sites at which LSW is recorded has more than halved in the last 15 years (chart from forthcoming @birdsinwales.bsky.social 2023 Bird Report). Sad times. #BirdingWales (1/2)

In Wallonia (BE), only 1,3% of the territory is under strict nature protection regime. The new regional government is committed to reaching 5% by 2030, but at the same time is cutting in half the budgets for acquisition of land to set up nature reserves. Find the error. #Conservation #biodiversity
Nature : passer à 5 % d’aires protégées en Wallonie, mission difficile après 2026
Nature : passer à 5 % d’aires protégées en Wallonie, mission difficile après 2026
La Wallonie vise 5 % de terres protégées d’ici 2030 (contre 1,32 % aujourd’hui). Grâce au plan européen, 958 hectares ont été acquis, mais l’avenir du financement après 2026 reste incertain.

Exceptional work by @migueldefelipe.bsky.social revealing how the state of wetlands around Doñana National Park has flyway-scale impacts for waterbirds. #ornithology
Crucially: rice fields don't host huge nrs of certain species bc birds prefer them, but bc of lack of suitable natural wetlands.

No. What happens in Doñana DOES NOT STAY in Doñana.
After more than two years of work, we’ve published an article demonstrating that the poor condition of Doñana negatively affects waterbirds across the ENTIRE continent!
