The Brenig Osprey Project said in a social media post: The “horrible act of vandalism” took place around 21:45 at Brenig Lake, a reservoir in Northern Wales.
There was a camera on the pedestal, and the organization just celebrated the mating pair laying eggs the day before.
North Wales Police Rural Crime Team said in a tweet on Saturday they believed the suspect or suspect had arrived by boat to cut off the platform.
Eggs are destroyed in the fall.
Rob Taylor, NWP’s rural crime team manager, said they were trying to find incentives for the crime and were monitoring local surveillance cameras for information from the public.
“The whole team has certainly been corrupted, and I am sure the whole community will, too,” Taylor said in a video on Twitter. “These birds bring joy to a lot of people, and I don’t understand who really can do something like that.”
Ospreys are fish-eating birds of prey, also known as hawks, sea hawks, and sea eagles. They’re extremely rare in the UK, with just 300 mating pairs across the country, according to the Dyfi Osprey project.
There are few mating partners in Wales.
The birds and their eggs are protected under wildlife and rural laws and the crime carries a prison sentence of up to six months and / or a fine of £ 5,000 (about $ 6,900), police said.
The Brenig Osprey Project, a collaboration between Dwr Cymru Welsh Water and the North Wales Wildlife Trust, said workers had cleared another platform they hope the birds would use for the new nests.
“The birds are fine and have just been spotted by an invading falcon,” Brenig Lake’s attraction manager Nick Kite told CNN in a Facebook message. Today, it is therefore reasonable to be optimistic that they will pick up that nest and lay eggs soon.
Ospreys typically lay two or three eggs each year, according to the Royal Society of Bird Protection.
