Two new species were recorded, Little Crake and Sharp-tailed Sandpiper. This was a year which, perhaps reflecting a warmer climate and less severe conditions to the north, saw a continuation of the trend of reducing numbers of wildfowl and waders. It also saw the earliest ever reports of several migratory species. JANUARY Despite force nine, north to northwest gales on New Year's Eve, the American Robin was still at Godrevy on New Year's Day and remained until 2nd February. Several of last year's other rarities also remained in the county at the start of the year; a Great Bittern at Marazion Marsh until 2nd April and another at Par Beach Pool until 16th February, a Eurasian Spoonbill until 24th February, an American Wigeon on Hayle Estuary until 29th March, a Green-winged Teal on Hayle Estuary until 7th January, a Surf Scoter at Feock until 12th April, a Lesser Yellowlegs on Hayle Estuary until 3rd May, a Ring- billed Gull at Helston Boating Lake until 9th, a Ring-billed Gull at Par Beach Pool until 16th, eight Bearded Tits at Marazion Marsh until 28th March and two at Par Beach Pool until 25th March.
