[First paragraph…]On 16 Nov 2005, we observed a pair of variable oystercatchers (Haematopus unicolor) at the eastern end of Rabbit Island, Tasman Bay. Both birds were banded and each had an orange Darvic flag on the tibia indicating that they had been marked as chicks in Tasman Bay. A search revealed a nest with 2 eggs. On 16 Dec, 1 egg had been lost and the other was pipping; the adults were aggressive towards us. The chick was seen following the parents on 18 Dec and until 21 Dec but was not seen after that date. There were many stoat (Mustela erminea) tracks in the vicinity.
