THE Scottish Parliament is said to be finally free from its pigeon plague after a nine year battle with the birds.
The pests have been plaguing the £414m building since it opened in 2004.
And in 2009, concerned officials called for help from pest control firm NBC to help combat the problem.
As part of a £40,000 annual contract, birds of prey have been flown around the building twice a week in a bid to scare off the feathery fiends.
And now it appears to have worked with no pigeons nesting on the site and the number of bird sightings having dropped by 50 percent.
Area manager for NBC Bird and Pest Solutions, Ian Cain, said: “Our birds have now established their own territory.
“We’re now down to a couple of visits a week.”
Under the contract the birds of prey cannot be allowed to kill the pests but simply scare them away.
Other deterrent methods are also used daily including spikes, wires and gels.
A Scottish Parliament spokesman said: “Our falconry contractor uses birds of prey, which is just one of the methods we used to deter pigeons from Holyrood.”
