PORTLAND — A smartly dressed young couple has moved in at the Oregon Zoo just in time for Valentine’s Day. Two young Humboldt penguins, Luna and Milo, arrived last month from the Roger Williams Park Zoo in Providence, R.I., and have now joined the 16 other penguins in the zoo’s penguinarium.

Luna means “moon” in Spanish, and the younger Milo, who turned 2 on Jan. 10, seems over the moon for her — following Luna around, forfeiting his fish to her, and generally taking on a submissive role. The two new penguins are a bonded pair, but keepers aren’t expecting any nesting activity from them this year as they’re still settling in.
