In rather inclement weather conditions – cold and snowing half the day – this survey brought overall much reduced bird numbers, in particular numbers of geese, compared to the December survey. With 4000 geese (almost half of them Tundra Bean Geese and Greater White-Fronted Geese) the number was only two thirds of that of December, with no Swan Geese visible; probably many migrated further South. Also, Han River was full with drifting ice and almost no gulls or ducks were visible.
However, the number of small birds, in particular buntings, seems to have increased a lot, with among others more than 400 Rustic Buntings, a globally vulnerable species seen.
