Jeff Schrier | Scooter, one of six African penguins at the
Children's Zoo at Celebration Square in Saginaw, shows off her sweater.
Scooter did not molt this season and is stuck with a back full of frayed
feathers. The other penguins molted to keep warm and waterproof for
winter. Sometimes Scooter's zookeepers will give her a dog sweater to
wear to keep her warm, but the other penguins pick at it, instinctively
gathering material to nest.
SAGINAW -- Someone’s looking rather shabby-chic these days in the penguin warming house at Children’s Zoo at Celebration Square.
But
the reason for Scooter’s bright dog cape, frayed by the constant
pecking of her fellow African penguins, is one zookeepers take very
seriously. Scooter didn’t molt this year, which means she also didn’t
grow the new feathers that weave into a watertight coat.
While her
caretakers make sure she doesn’t go into hypothermia, they’re studying a
similar case in California where a custom-made wet suit triggered the
molting process. With a little help, said zoo director Nancy Parker, the
Neoprene vest could become the latest addition to Scooter’s growing
wardrobe.
“People always think of penguins as cold-weather birds
but ours come from South Africa, where they’re happiest when the weather
is in the 60s,” said visitor services specialist Robin Carey. And even
though they live along the coast-line, “it’s not humid,” she added.
Like
most birds, they also molt each year, beginning with a two-week food
binge that doubles their weight before they lose their plumage.
“It
literally looks as if they’ve exploded,” Carey said. “There are
feathers everywhere and these cute little downy penguins running
around.”
They stay away from the water – hypothermia is a real
risk in that state – and live off their stored fat while the new
feathers come in. In a zoo setting, of course, they don’t need to go in
the water to eat, “but it’s instinct,” Carey said. “We put the food out
but they might eat one fish a day, at the most.”
Every so often,
she added, penguins might miss a season of molting. It’s rare, Carey
said, but it happens. But Scooter hasn’t shown new growth, either, and
that’s cause for concern.
“Penguins have about 70 feathers per
square inch, and they have oil glands at the base of their tails that
produce the oil they spread over their feathers,” she said. “They need
that insulation.”
An attentive zookeeper in Saginaw, browsing on
the Internet, found an article titled “Why and How to Make a Penguin
Wetsuit,” Parker said. It told about Pierre, a 25-year-old African
penguin at the Steinhart Aquarium in San Francisco who didn’t molt for
four years.
He also withdrew from his colony, something keepers
are finding in Saginaw as the other penguins harass Scooter, who was
hatched in 2001. While some might think the other ladies are jealous of
her fancy penguin-wear, it has more to do with the approaching breeding
season, Carey said, and looking for fancy threads to line their nests.
Zoo
keepers in San Francisco tried several treatments, including heat
lamps, on Pierre but he remained plucked until a seamstress experienced
in making children’s costumes created a Neoprene vest. Within six weeks,
his feathers had completely returned, possibly, they theorized, because
the energy his body used to stay warm went instead toward sparking
regrowth.
“Best of all, they included a pattern for making our
own wet suit,” Parker said, brandishing the paperwork that calls for at
least three square feet of black 3-millimeter Neoprene and 10 inches of
black Velcro hook side and another 20 inches of the loop side. “This is something we could do.”
Visitors
to Saturday’s Arctic Zoo Fest won’t see the penguins – they need
temperatures of 37 degrees or higher with no wind chill, Parker said –
but making appearances are the Forgotten Forest and Stock Yard
inhabitants and a few kangaroos if the sun’s shining.
Activities include kids’ crafts, chainsaw woodcarving demonstrations and a meet-and-greet with real sled dogs.
“We’ll
have the wolves and the bobcat, and the reptile building will be open,
too,” she said. Also watch for the train, on its way back from
Scientific Brake and Equipment Co. where it was spiffed up for the
coming season.
“Weather permitting, it’s going to be on track,” Parker said.
The
Arctic Zoo Fest takes place from noon to 4 p.m. Saturday at the
Children’s Zoo at Celebration Square, 1730 S. Washington in Saginaw.
Admission is free but donations are welcome. Carousel and train rides
cost $2.
The zoo kicks off its new season the last Saturday in March, with gates open from 10 a.m. to 5 p .m. daily. Admission costs $5.
