Big viewing windows? Check. Realistic rockwork? Check. Mood-setting mural? Check. Chilly air and water? Check. Wave machine creating ocean-like swells? Check. Penguins? On the way. From where? From SeaWorld in San Antonio, Texas. The gentoo and macaroni penguins at the Tennessee Aquarium are part of a breeding loan progam. Four of the macaroni penguins were at the Pittsburgh Zoo, but also part of the SeaWorld loan program. The other 16 birds, ten gentoo and six macaronis are coming from deep in the heart of Texas. They will travel all that way in refrigerated trucks. (Insert old joke here.) Q:"Why do penguins travel in refrigerated trucks?" A: "Because they can't fly." Ba-doom-boom.
