African penguin Reproduction: 7th Generation Captive Hatched Penguins

All of the penguins in the Academy’s exhibit are captive hatched, some are even seventh generation.  The Academy has had 108 chicks hatch out since 1983.  These birds stay either at our facility or move to another as part of a cooperative breeding program (see Species Survival Plan blog).  The photo is of Dunker and Safara at 4 weeks old.  They are now juveniles and are on exhibit.  Dunker is the penguin that looks like he has a small bald patch on his lower back, he has an orange wing band on his right wing and a white band on his left wing.  He sustained an injury when he was young and the feathers grow less densely in this patch.  Once he molts (which is due soon) he will replace those feathers and look the same as the rest of the adults.-Pamela Schaller

  1. I have nicknames for the penguins since I have been watching them for many months without knowing their real names. I always thought the patch on the back of Dunker looks like a Kick Me sign, so I call him KickMe. Good thing I know his real name now, though I may have trouble recognizing him without his little sign! :)

    How did he get injured? Did he fall or did another penguin hurt him? I have seen the penguins fight sometimes.

  2. Thank you for the info about Dunker. I’m always wonder about the patch and worried for him. I hope the injury won’t harm him further in the future.

    Love all of them and thank you for taking care of those adorable creatures.

  3. So that little guy is Dunker! He’s always standing between those two rocks facing the walkway behind. I guess that’s his territory. :)

  5. “Dunker” was injured between Day 3 and Day 11 of his life. There were skin/feather injuries from the parent. This was the couples first offspring and they were inexperienced in their care. “Dunker” was hand raised by the staff from Day 12 on. Since “Dunker”, the couple has reared another chick successfully.

  7. Dear Penguins and helpers: I hope your taking care of the one who lost his feathers. I feel bad for him. Why is it that a wet suit does not hurt his skin? Remember to take good care of all the other penguins too. Have a good day! And another thing….when are you going to take them back home to Antartica?
