Environment Minister Stewart Stevenson, who also chairs PAW Scotland, said:
Operation Easter was started by Tayside police back in 1997. The police, National Wildlife Crime Unit and the Royal Society for the Protection of Birds began working together to share intelligence and ensure effective enforcement action against the egg thieves.
This has resulted in several seizures of egg collections over recent years across the UK. The concerted effort has seen the number of active egg thieves reduced to an all-time low.
But Charles Everitt, Scottish Investigative support officer at the UK National Wildlife Crime Unit, warned that one of the biggest dangers now was complacency.
Said Mr Everitt:
Anyone who witnesses or suspects that people are involved in egg theft or any other rural crime should contact CrimeStoppers on 0800 555 111, or their local police.
