Calls heard in the territory of group 4 may have indicated the presence of a concealed newly fledged chick. An immature seen briefly in the territory of group 5 may have belonged to that group, and the behaviour of the adults in group 6 suggested they may have had a nest. Two adult Magpie Robins seen in a territorial dispute with the adults of group 9 may have been from group 8 or from a territory we missed between groups 8 and 9. that we found every Magpie Robin on Frigate: but we believe we located every occupied territory on the two plateaux. Seven of the 10 groups were on the main plateau and one group occupied the entire plateau of Grand Anse. The group around the house at Anse Pare was at sea level, but the area around the beach and house was not extensive enough to be called plateau. The remaining group was at an altitude of 25 m, again close to a house and gardens. !10. CONTOURS IN MGTR65 0 5001. PARC 'ig. 1. Frigate Island, Seychelles.
