Hundreds of zoo visitors sign a super-sized birthday card for Samudra, an Asian elephant born at the Oregon Zoo three years ago. Elephant habitat's Director Mike Keele says Sam is a ton-and-a-half of fun for zoo visitors and staff, but not always for his mom, Rose-Tu, and his aunts. Keele says Samudra was 260 pounds at birthday and is now about 3,000 pounds. He gains three pounds a day and is expected to reach full-size between the ages of 25 and 30; then weighing in around 14,000 pounds.
