Notes: The annual SOOTY SHEARWATER migration has begun. At the beginning
of the hour shearwaters were moving by at 1100birds/min by the end of the
hour they had slowed to 220birds/min. A large raft of birds could be seen
sitting on the water. At least 2 PINK-FOOTED SHEARWATERS went by over the
period. A POMARINE JAEGER was closely associated with the shearwater flock.
At least 4 PARASITIC JAEGERS were working shearwaters and terns.
