Numerous young seal pups are venturing onto Oregon beaches, where they are at-risk from well-meaning coastal visitors who mistakenly try to rescue them.  Oregon State University marine mammal biologist Jim Rice is urging the public to refrain from touching or approaching the seal pups, which in most cases are not orphaned or abandoned, he pointed out. They frequently are left on the beach by their mothers, who are out looking for food.  “It is perfectly normal for seal pups to be left alone on the beach in the spring,” said Rice, who coordinates the statewide Oregon Marine Mammal Stranding Network headquartered at OSU’s Marine Mammal Institute at the Hatfield Marine Science Center. “Newborn pups typically spend several hours each day waiting for their mothers to reunite with them.”  “Adult female seals spend most of their time in the water, hunting for food, and only come ashore periodically to nurse their pups,” Rice said. “But the mothers are wary of people and unlikely to rejoin a pup if there is activity nearby.”
