For most Swedes the Bohemian Waxwing is a winter visitor rather than a breeding bird.
Berry specialist: flocks descend on rowan, whitebeam, hawthorn and windfall fruit in parks and residential areas and can strip a berry tree in a short time.
Intoxication: fermented, over-ripe berries can leave the birds mildly intoxicated, which sometimes leads to collisions with windows.
Numbers: how many reach southern Sweden varies greatly from year to year.
