During a ground visit on 7 April 2002 to a Northern Goshawk nest in the southern Netherlands, a very small egg among three normal-sized eggs was seen in the mirror. The ringing visit on 3 June revealed a single nestling (female) and three unhatched eggs (hidden underneath nesting material), among which the runt egg. The volume of the latter was only 29% of that of the other two unhatched eggs (Table 1), i.e. 16.2 cc.
