That's seriously risky advice!! If you destroy the nest you are breaking the law unless you can prove the nest is a risk to human health and safety (which you might be able to argue for a satellite dish but probably not for a tree), serious damage to agriculture or other reasons such as conservation of a rare species etc....
A nest is protected as soon as it is being built right up until chicks have definately permantly left and you are sure the nest won't be re-used.
You could try bird scaring techniques though.... plastic peregrine? flappy plastic things etc? or learn to love them in their big, dopey pigeon way of life... Small birds are only afraid of being landed on by pigeons, pigeons would never attack them - they like seeds and seedlings not other birdies....
