opmerkingen	24-26 April, Bosbaan, Amsterdamse Bos, Amstelveen, Noord-Holland, male, photographed (T M van der Have, W van der Have; van der Have 1978). This record was previously accepted as relating to two individuals. One of the observers has recently reported doubts that actually two individuals were involved (as reported for the first day in van der Have 1978); according to the observer’s original notes, only one individual was seen on each date. Differences in light circumstances on the three days of observation were probably the cause that this observer at the time thought that the bird on the second and third day was a different individual (Tom van der Have in litt). Therefore, the record is now accepted for one individual.
