Pomarine Jaeger A new high total of 60 Pomarine Jaegers was recorded in April. Many of these were seen at a considerable distance from land, up to 500 miles. Most were headed north. Several were observed to chase birds in feeding flocks. Wedge-tailed Shearwaters, Sooty Terns, Arctic Terns, Red-tailed Tropicbirds, and even a Frigatebird were among their "victims". Many had fine adult breeding plumage with prominent twisted central rectrices. Long-tailed Jaeger Two small jaegers, one a light phase and the second an intermediate phase, which had very prominent pointed central rectrices in excess of four inches were presumed to be this species. In addition, 10 more were termed jaeger species. Several or most of these may have been long-tailed Jaegers but their central rectrices were not as well developed. Red ? Phalarope Four phalaropes, probably Red Phalaropes, were seen in April, the tail end of the spring northward migration which reached its peak in March in 1964 and 1965. Gull species On 22 April a bird which could only have been a gull was described in detail by the best informed of the crewmen on watch. It was medium sized and presumably in adult plumage.
