PORTLAND, OR (KPTV) -

Look out, Lily the baby elephant. There's a new adorable baby in town.

Tilly, one of the Oregon Zoo's two North American river otters, gave birth to a male pup in late January.

It's the first river otter to be born at the Zoo, and it weighed just over 4 ounces at birth. The baby otter has already tripled in size because of his mother's naturally high-fat milk.

Keepers haven't decided yet on a name for the pup, but it's likely he'll be named after a local river or waterway.

If all goes swell, zoo visitors should be able to see the new baby otter in the Cascade Stream and Pond section at the zoo in a few months.

So far, the pup has not opened his eyes - it usually takes three to six weeks for that to happen. It's then expected to be about five weeks before he starts walking.

"Surprisingly, swimming does not come naturally to otters - pups must be taught to swim by their mom," a zoo spokesman said.

So far, Tilly, who was named after the Tillamook River, has taken to motherhood like "an otter to water," but the zoo is tempering its optimism because first-time moms aren't always successful.

"Tilly is doing all the right things and appears calm and comfortable," said Amy Cutting, zoo animal curator.
