Six Macaroni penguins from Biodome de Montreal have arrived at the Galveston facility along with five Gentoo and four Rock Hopper penguins. After a month in quarantine, the penguins from Canada will join the Gentoo, Rock Hopper and King penguins already on exhibit.

"Adding these penguins will make for a more diverse collection, and will bring the total number of birds to 90," said Diane Olsen, assistant curator at Moody Gardens. "Our exhibit will also more closely mimic nature in the sub Antarctic." Macaroni penguins live among Gentoo, Rock Hopper and King penguins in that region.

Named for the conspicuous yellow and black feathers in their "caps" as in the song Yankee Doodle, Macaroni penguins resemble Rock Hopper penguins that share the trait. Their average weight is about 11 pounds and they can grow 20 to 28 inches tall.
