SPECIES ACCOUNT Black-footed Albatross At least 37 birds of this species were seen on the April cruise, a 44% decrease from the 66 seen in March. The large gatherings of birds north of Oahu which were noticed in March were no longer present in April. The birds were mainly distributed north of the main islands while one bird was attracted by the ship to 18°N. Three of this species were banded. Laysan Albatross Only three of this species were seen in April, a 70% decrease from 10 in March. The birds were distributed along the northern end of the gird. Pink-footed Shearwater ? Eight individuals, thought to be a form of Puffinus creatopus, were seen in April. On 16 April three of this species were seen in a feeding flock of Wedgetail Shearwaters and Sooty Terns. The birds' large size, darkish underwings and short, hump-backed arcing manner of flight make it distinctive. Wedgetail Shearwater Numbers of this species increased 239%, from 104 in March to 352 in April. 127 of these were dark phase, the great majority of which were seen in the southeast corner of the grid area, indicating the utilization of this area by southern populations. Greatest densities were experienced
