Male or Female? Can You Tell The Difference?
The bills of Galápagos penguins help us determine sex. Males, like this one, are slightly bigger, and have whiter chins and thicker bills than females.
Galápagos Penguins Molt Twice a Year
It takes a lot of energy to stand on the shore and fast for 10 days or more to complete the molt. Photos tell us when penguins are molting.
The Age is in Feet
Feet become blacker as penguins age. Photos of a juvenile's feet and face can help us determine the penguin's age.
Groups of Penguins are Informative
Who is ready to molt? Group shots allow us to compare penguins and better tell whether they are breeding or not.
Nest Location and Quality
Nests are critical to reproduction and survival of the species. Photos and locations help track where penguins are and the quality of nests available.
