2 SPECIES ACCOUNT Black-footed Albatross Numbers of this species dropped 46% from 37 in April to 20 in May. This decline in numbers was accompanied by a northward trend in distribution. The southern limit of the range of this species seems to coincide with the convergence area between the North Pacific Central Water and the California Current Extension. One of this species was banded and released on 14 June 64. Wedgetailed Shearwater Numbers of this species rose from 352 in April to 1637 in May, an increase of 365%. Dark phase birds predominated south of 13°N this cruise, indicating a northward extension of the feeding grounds for the southern populations. In feeding flocks around Oahu, there were proportionately fewer Wedgetails than previous months, due probably to the beginning of egg laying in main Hawaiian Island colonies. Sooty Shearwater The last of 14 Sooty Shearwaters seen this month passed northwest on 27 May. Between 18 March and 27 May 1967 of this species were observed, all heading approximately northwest. Peak numbers were observed 3 April when 1337 were seen. Christmas Island Shearwater Two of this species were seen in the grid area this month, one north of Oahu and the other toward the southern end of the grid.
