Strathallan Estate’s ospreys which were at the centre of much of the opposition to T in the Park are fine and “behaving normally” following the end of the festival.
Wildlife groups had pleaded with Perth and Kinross Council to block the festival moving to the estate from its former home at Balado, arguing that the protected birds would be disturbed by the noise.
However, it seems the birds proved unflappable.
A spokesman said: “The ospreys were closely monitored over the weekend and both adult birds are still present at the nest site with their chicks, and behaving normally.
“The package of measures stipulated in the planning consent, which RSPB Scotland called for, including changes to the festival site layout, introduction of buffer zones around the nest and restrictions on activities including fireworks and lighting, all appear to have been successful in preventing disturbance to the birds.
“However, the event isn’t completely over yet. It’s extremely important that sensitive management of the site is maintained during the clean-up operation.
“When this is concluded, the festival needs to be thoroughly reviewed before it can proceed in 2016.”
Festival director Geoff Ellis said: “The site’s very own high-flying birds, a family of four osprey, have been undisturbed by the festival and there has been no change in their behaviour during the event.”
