Gentoo Penguins

The Gentoo Penguin is found in parts of the Antarctic, the United States and England. Its distinguishing characteristics include a lower or red-orange mandible and white patch around the eye. Juveniles and adults share a similar appearance. They exhibit sexual dimorphism: males are larger than females. Adult males weigh up to 12.35 lbs. (5.6 kg) and females reach a maximum weight of 11.24 lbs. (5.1 kg). Two subspecies exist, one inhabiting the Antarctic Peninsula, the other in the Subantarctic region. Habitats and nesting sites differ according to location. In the Subantarctic, individuals nestle eggs between tussocks. Gentoo Penguins situated on the Antarctic Peninsula prefer beaches and stony regions free of ice. Breeding colonies reside inland or along the shoreline. Pairs fashion stones into makeshift nests, resembling a rough, circular pile. Females lay a clutch of two eggs. Both parents take turns in the incubation process, which lasts a little over a month.
