Extreem laat broedsel van Grote Lijster Turdus viscivorus bij Rolde

On 11 August 2003 a Mistle Thrush nest was discovered by following a parent transporting food. The nest contained three one-day old chicks; onset of laying was calculated at 25 July. On 16 August, when the young were six days old, the youngest chick was in poor condition (Table 1) and the growth of its wing was retarded. During the next visit the youngest chick was gone, but its older siblings were still in good condition. On 23 August the young had left the nest and were hidden in a potato field. This breeding was later than any one found in the files of the Dutch nest card scheme (n=l 31 cards, 1994-2002), or in Europe (as collated in Cramp (1988) and Glutz von Blotzheim & Bauer (1988)).
