A three-egg nest on Promise Island found June 28 was rob- bed, almost certainly by a Parasitic Jaeger. Others found on this island were: June 25 five eggs, another July 8 with 5 eggs. On July 13 a nest with seven eggs was found on Rockhouse Island. Nests were found also on an islet northeast of Out Island on July 19. The first young were seen on July remained on the land until at least July 13. A male collected June 19 weighed 2,548 g., its measurements in mm. were, wing 307, bill 63, tarsus 45: a female col- lected June 28 was not weighed but had the following measurements in mm. wing 270 and 273, bill 52, tarsus 55. The wing colour of this last bird was characteristic of the subspecies indicated. A female collected by Savile on June 15, 1950, weighed 2,127 g. King Eider. Somateria spectabilis. Breeds but is much less common than the preced- ing species. The offshore spring arrival is evidently considerably later than that of the Common Eider for in 1950 Savile's party did not record it until June 12 and in 1967 my first observation was on June 8 when a single male only was seen flying over the shore of Promise Island. Two days later about ten of both sexes were seen at sea near Fairway Island. The first appearance on fresh water was also later than in the case of the preceding species, namely June 19 in 1967, and the withdrawal of adult males from fresh water took place about July 6. A nest consisting only of a ring of down, but no eggs, was found on June 29 on Promise Island, and another on the same island on July 8 had five eggs. A male col- lected on July 5 weighed 1,754 g.
