A police constable amassed a collection of 649 rare birds' eggs by stealing from nests, often while on duty for Suffolk Police, a court has heard.
Michael Upson, 52, travelled across the UK to collect eggs, but most were taken from areas near his home in Halesworth, Norwich Magistrates' Court heard.
He admitted having the eggs in his possession, contrary to the Wildlife and Countryside Act 1981.
Upson, who has since retired, is due to be sentenced on Thursday.
