Pomarine Jaegers recorded per party hr on the Honolulu Christmas Count, O'ahu,

1944-2007 (see Count Page). Higher numbers from the late 1950s to the early

1980s reflect attraction of this and other seabird species to a wastewater outflow off

Sand Island. Variation in count totals during this period reflects daily variation in the

presence and/or visibility of jaegers from shore, dependent on outflow, current, and

weather conditions (see text).
