opmerkingen 19 April, Hippolytushoef, Wieringen, Noord-Holland, first-winter male, photographed, videoed (H Niesen, L J R Boon et al; Birding World 15: 150, 2002, Dutch Birding 24: 183, plate 162, 2002), and 22 April, Badweg, Schiermonnikoog, Friesland, photographed, videoed (B Henstra, T Talsma et al). Study of the respective photographs led to the conclusion that the same bird was involved in both cases. Close and prolonged study of (photographs of) the Hippolytushoef bird also indicated that it was the same individual staying in West-Vlaanderen, Belgium, from November 2001 to March 2002 (Verbelen et al 2001; Dutch Birding 23: 398, plate 462, 2001, 24: 69, plate 55, 2002). Close scrutiny did not reveal any oil stains on its plumage and the CDNA therefore concluded that there was no direct evidence that the bird was ship-assisted, although it may likely have been part of the ship-assisted influx of Snowy Owls in western Europe in late 2001 (Verbelen et al 2001). However, the principle 'innocent until proven guilty' implies that this bird had to be admitted to the Dutch list. Annual Report 2002.
