opmerkingen 29 December, Groet, Schoorl, NoordHolland, three, incl 1 male, sound-recorded (R Slaterus). This was by far the largest invasion ever recorded. It started in August, when it included apparently just arrived, extremely tame birds. Among these were highly strange records of a bird landing on a tripod and even one landing on a coffee table aboard a ship. The invasion progressed slowly until the end of October, when the first sizeable groups became apparent, and then peaked around Christmas. The number of recorded birds in 1997 was 111, but the total of the invasion in 1997/98 was calculated at 181 birds (Ebels et al 1999). Annual Report 1997.
