This is the time of year when harbor seals give birth to their pups on the Oregon coast. Jim Rice, with the Oregon Marine Mammal Stranding Network, says don't approach a pup if you see it alone on the beach. Chances are, the mother is just out seeking food for the pup. Rice says you should stay at least 50-yards away.  And if you have a dog, keep it on a leash. Violation of the law is a federal offense.
