SHARE Caption Only: Going ape over a love song

A Siamang ape named Sutera tries to serenade Simon, left, at Seattle's Woodland Park Zoo. Simon lost his companion, Sai Buri, to a tumor last year, so the zoo acquired Sutera in hopes that the two would do more than just swing and sing. Zookeepers are watching the pair's budding relationship with interest, and they hope that offspring will result someday.
