Two Rooks were combing the playing fields at Moulin this evening, intently picking over the grass for (I assume) leatherjackets and other prey items. I wondered if they were locally-breeding birds. One or two pairs are about here all winter and sometimes appear in the summer months too. I guess it is possible that there is a tiny nesting colony somewhere nearby. A few years ago, two or three pairs set up a short-lived rookery in Murdieston Park which persisted for a few years before dying out.
