Species Account Black-footed Albatross Only three individuals were seen, one just south of Oahu and two in the northeast corner. The considerable reduction in numbers from 20 in May 1964 may indicate either an earlier breeding season this year or a relatively unsuccessful one. In either case birds would probably be less apt to occur in the area. Water of less than 34.8 percent salinity, which has been suggested as a possible range limit, extended nearly throughout the area as well. Wedge-tailed Shearwater Numbers increased 46 percent from 516 in April to 958. However, this was far short of the 1637 recorded in May 1964. In May 1964 a third or more of the total was seen at the southern end of the area; this density center failed to appear this month. Numbers around the high Hawaiian Islands were even higher this month, though. Large numbers were taking part in feeding flocks just north of Oahu. Dark phase birds penetrated just into the extreme southern end of the area. Most dark birds were molting. Newell's Shearwater Two general density centers for this species were seen in May, one in the southeastern corner, and the second around the high Hawaiian Islands. This distribution pattern has been seen in several previous months as well. Numbers increased to 49 this month,
