Original Caption: Adelie Penguins waiting for the melting of the snow so as to build their nests on the rocks beneath.
This colony of Adelie Penguins is making a lot of noise, especially the two males in the background who are trying to gain the attention of the same female! Penguins use sound to communicate, and they can even recognize each other's calls. After they're done conversing, the male that the female chooses will become her mate, or partner, for the entire breeding cycle. Once the snow melts, they will build nests of pebbles on the rocks beneath and share the responsibilities of incubating their eggs as well as feeding and protecting their chicks once they hatch. Their chicks won't be able to dive straight into the water like their parents, though. It will take nine weeks for their future chicks to grow waterproof feathers. Once they have these feathers, they'll be able to plunge into the seas around Antarctica with their parents to hunt krill and other sea life. While their prey will not see these flightless birds swooping down from above, they better be on alert because the Adelie Penguins are fast swimmers!
