The SeaWorld Orlando Aviculture Team marked National Penguin Awareness Day yesterday with its own “penguin chick” boom. Since Nov. 30, a total of 15 penguin chicks have hatched at Antarctica: Empire of the Penguin, the all-new attraction which features a colony of more than 250 penguins from four species – king, Adelie, Gentoo and rockhopper. Starting Wednesday (Jan. 22), SeaWorld Orlando fans will have the chance to help name a Gentoo chick, and can cast a vote for their favorite name by visiting SeaWorld Orlando Facebook page.
