Black-throated Thrush / Zwartkeellijster
Turdus ruficollis atrogularis 0,5,1
15-25 December, Harlingen, Harlingen, Friesland, first-winter male, photographed, videoed (P de Bruin, R Cazemier, E Winkel et al; van Dijl 2003; Birding World 15: 499, 2002, Dutch Birding 25: 69, plate 56, 73, plate 59, 2003).
On some photographs, this bird seemed to show some rufous in the outer tail-feathers. However, this was not considered convincing enough to label the bird as a probable hybrid with Red-throated Thrush T r ruficollis. After the first in March-April 1981, subsequent records were in October 1982, January-March 1996, April 1998, November 2000 and December 2002.
