The Brenig Osprey Project said in a social media post that the “horrific act of vandalism” occurred around 9.45pm at Brenig Lake, a reservoir in North Wales.
There were cameras on the platform and the organization had just celebrated the breeding pair laying an egg the day before.
The egg was destroyed in the fall.
NWP Rural Crime Team Director Rob Taylor said they were trying to determine the motive for the crime and checking surveillance cameras in the area calling on the public for information .
“The whole team is absolutely devastated and I’m sure the whole community is too.” Taylor said in a video on Twitter
. “These birds give a lot of people a lot of pleasure and I just can’t figure out how someone could do something like this.”
Ospreys are fish-eating birds of prey also known as fish hawks, sea hawks and sea eagles. They are extremely rare in the UK with only around 300 breeding pairs nationwide, according to the Dyfi Osprey Project.
There are only a handful of breeding pairs in Wales.
The birds and their eggs are protected under the Wildlife and Countryside Act and the crime carries a sentence of up to six months in prison and / or a fine of £ 5,000 (approximately $ 6,900), the police said
The Brenig Osprey Project, which is a partnership between Dwr Cymru Welsh Water and North Wales Wildlife Trust, says workers have cleared another platform they hope the birds will use for their new nest.
“The birds are fine and have just been seen from an osprey,” Nick Kite, director of tourist attractions for Brenig Lake, told CNN in a Facebook post. “They were seen near the nest we opened for them earlier today, so there is cause for optimism that they will take this nest and lay eggs soon.”
Ospreys typically lay two or three eggs each year, according to the Royal Society of Bird Protection.
