Birds who are dependant on clear ground to feed, such as Lapwings, Golden Plover and Skylark will move to find areas clear of snow and frost. At times these cold-weather movements can be spectacular and can be witnessed anywhere in the country, not just along our coasts.

As smaller waterbodies freeze, wildfowl will be forced to search for new and as yet unfrozen sites. It will be well worth checking any local gravel pits or lakes for new arrivals - Goldeneye, Tufted Duck and Pochard may well be on the move, along with surface feeders such as Teal and Wigeon.

Geese, being grazers, also struggle during prolonged snowfall, and Bean and White-fronted Geese have been on the move during the last couple of days. Further geese (amongst other species) may also arrive from central Europe as snowfall covers previously clear areas, in what has been a relatively mild winter so far.

Iceland and Glaucous Gulls have been increasingly noted along coastal areas in the north and east of Britain and Ireland, including up to 37 on Shetland alone. Strong northerly winds over Friday may push birds further south and even to inland areas. Indeed, single Iceland and Glaucous Gulls have even reached the BTO Offices in recent days. Any large congregations of large gulls will be well worthwhile checking for 'white-wingers' over the weekend.

At coastal sites, there is an outside chance of even rarer gulls, such as Ross's or Ivory. One of the latter has already graced the North Sea coast of Germany this month so could well put in an appearance anywhere along the east coast of Britain.
