This guest post comes to you from Sam Herman of the Aquarium's Visitor Experience department. You may know him from the Exhibit Galleries Blog, where he's posted about fish-eating jellies and airborne right whale skeletons. Sam has also had the opportunity for the past year to cross-train in the penguin department, giving educational presentations from within the exhibit.
If you’re a regular blog reader, you probably already know how we tell our penguins apart in the exhibit – their color bracelets! As Andrea has discussed in this previous post on the Penguin Blog,
African penguins can be identified by their unique, fingerprint-like
spots on the chest and belly. However, that’s pretty difficult to see
when they’re swimming around
(and a lot harder to memorize!) so instead we put bracelets on the
penguins’ wings to make it easier. We also use the bracelets to identify
gender, left wing bracelet means it’s a male and right wing bracelet
means it’s a female.
A male and female penguins in the exhibit, note the bracelets on their arms.
you can imagine there are a lot of different color patterns to
remember! Sometimes, it becomes just a tad bit harder because we’ll
change a bird’s bracelet. This may not seem like a great idea since
everyone has already memorized the name/color combination, but it’s
actually a very important change! African penguins
are an endangered species and one way that the New England Aquarium is
helping to protect them is by participating in a breeding program called
the Species Survival Plan. When the color is changed it is usually done to indicate that we have a new, successful SSP breeding pair on exhibit!

After the past breeding season, we had an actual color change happen. We’re glad to report that Spheniscus
(female) and Ichaboe (male) have had their second successful breeding
season as an SSP approved pair and Spheniscus officially changed her
colors. In the past she was purple and white on her right wing, she now
has black and orange bracelet to match Ichaboe’s color pattern. She was
chosen to change because there is already a male with purple and white
bracelet: both she and her brother Demersus had the same color pattern
because their names, when combined together, create the scientific name
of the African penguin – Spheniscus demersus.

next time you’re at the Aquarium, see if you can see two African
penguins with orange and black bracelets. While you’re at it, keep an
eye out for all eight juveniles hatched during the 2011 breeding season.
See you in the galleries!

The Aquarium is home to more than 80 penguins who live in a bustling colony found on Level 1 surrounding the Giant Ocean Tank. The Aquarium breeds African penguins as part of a Species Survival Plan and promotes education programs about penguins around the world.
