The broad, neat pale fringes to the upperpart feathers indicate it is a juvenile (plainer upperparts with distinct spotting on coverts and more prominent neck ‘gashes’ in adult). Great Northern Divers have appeared almost annually in Northants in recent years. They are the commonest diver to occur in the County with 29 records in the last 45 years, outnumbering Red-throated and the rarer Black-throated with 23 records and 10 records in the same period respectively.
