Live Penguin Cams 

January 6, 2009

Wing Bands

The penguins are all banded with a thin plastic band.  This allows the staff to closely track individuals and identify them quickly.  There is a system to the bands that you can look for on the Penguin Cams.  Adults (birds with the white stripes on the sides of their heads and the single black stripe across their chest) have a single band.  Juveniles (dark headed penguins) have two bands.  Adult males are banded on their right wing.  Adult females are banded on their left wing.  The couples have the same colored wing bands.  Juveniles have an orange band that indicates their sex.  Juvenile males are orange banded on the right wing.  Juvenile females are orange banded on their left wing.    The above photo is of the penguin named “Robben”.-Pamela Schaller

  1. I love the CAS Penguin Cams! Thanks for the explanation of their wing bands. This makes even more enjoyable to visit the cams :)

  2. Is there a somewhere that shows a picture of all the penguins, with their names and arm bands?

    Thanks so much for keeping these webcams up and running! It really makes my day to see all the penguins hanging out, especially because I’d never get to see them otherwise. I live very far away from CAS!

  3. How many couples are there? Is there a mating season and therefore, do all of the eggs hatch at about the same time? How long is incubation? Thanks for allowing us the pleasure of looking at the penguins.

  4. There are 4 mated pairs, eggs are laid and hatch out year round (both in the wild and at CAS). Incubation takes 37-39 days.

  5. I would also like to see a “portrait hall” of the penguins.
