end of Roger Clapp's notes
0604 Small hunting flock of 10+ Wedge-tails
1417 Small flock 5+ Shearwaters and 30+ Sooty Terns
1735. Large flock consisting of 200 + 10 Wedge-tails, 20 Terns, 7 Frigate-birds, 1 adult Red-footed Booby, 9 Imm. Boobies.
Huge school of lfying fish plus what appears to be larger fish in the water.
At one spot a dead fish (white belly up) was seen floating just beneath the surface in a cloud of blood. There were sharks at this place.
The wedge-tails were flying (gliding) back and forth in large circles over a considerable area. No single birds were seen more than 200 yards from the flock. In other words all the birds were incorporated into the one flock and no birds were feeding as lone individuals. On two occasions at least sitting flocks were observed. There were always on the outside of the feeding flock and no flying fish were seen around them. In other words the resting birds sat just outside the feeding area. One of these resting flocks has over 65 birds at one point. Birds would occasionally leave ;this flock and join the feeding birds and conversely some feeding birds would leave the feeding flock and join the resting flock.
While on the water the birds would do preening movements and frequently hold up their wings for several seconds at a time. Upon taking off the birds would first raise their wings and shake them than with one or two hops into the wind they would rise up and join the feeding flock.
One wedge-tail was seen with a bright red tag extending from the leg under the tail (PJG).
