Sites were classified as R-rookeries, Y-year-round haulouts, and W-winter haulouts, although in some cases site used appeared to change over the course of the study period. NS denotes the site was not surveyed and animals likely missed, and (NS) denotes the site was not surveyed but it was not expected that any animals were missed based on the preceding and proceeding surveys. ?- denotes the site was not known to exist, and could have been overlooked. The estimated number of animals missed (and the number of missed sites) is given near the bottom of the table.
