Amerman, Kenneth 1965 October 8--One hundred adult shearwaters banded in area between road to dump and both shores. October 9--Two hundred adult Shearwaters banded. Many more found in area covered last night. Second hundred done in area between road to dump and x mitter bldg. A few were found with orange tags but no metal bands. October 10--Two hundred adult shearwaters done in area between road to dump and Xmitter bldg. Several more with tags and no bands found and rebanding. Leg sizes vary a good deal; some of the bands newly put on seemed as if they could slip over the foot. Five hundred adults banded in area of heaviest previous banding. Cannot estimate whether this means overlapping populations or a very large number have slipped their bands and perhaps tags as well. Total population in this area cannot be more than seven hundred to eight hundred. Population seems to fluctuate with cycle of moon. For shearwaters, lowest at time of full moon, then increases again. May merely reflect different time of returning at night--may come in later at night as moon gets higher. Bob suggests may reflect behavior of food organism. Longer feeding time for shearwaters with higher and brighter moon? For Sooty Terns, population had dwindled to -- ten in day, twenty- thirty at night. At time of full moon or just after suddenly they jumped back to about one hundred at night. October 13--Two hundred adult shearwaters banded along left side of causeway and Xmitter bldg. Finding an average of five to six per night (per 200) with tags and no bands. Six frigates banded.
