This study identified sex and age as the most important factors influencing the selection of haul-out zones. A haul-out pattern was observed on days when both low tides occurred during daylight hours: the number of animals hauled-out during a morning low tide was fewer than those during the afternoon low tide regardless of weather conditions.enCreative Commons BY-NC-ND 4.0-USHarbor SealsMarine BiologyThesis / Dissertation
