EDINBURGH, SCOTLAND - JUNE 10: Adult gentoo penguins keep an eye on their newly born chick at Edinburgh Zoo on June 10, 2011 in Edinburgh, Scotland. The gentoo chicks which started hatching in early May are looked after by both parents who regurgitate part digested food. When the chicks are hungry they peck the beaks of their parents to signal feeding time.

Gentoo Penguin
Scientific name: Pygoscelis papua
Size: 5.6 kg (m), 5.1 kg (f)
Nest type: in colonies in the open
Favourite food: krill and fish
This is the most northern penguin of this genus and, in many other respects, the odd one out. In contrast to Chinstrap and Adelie Penguins, some Gentoo Penguins can be found around their breeding colonies all year round and they forage much closer inshore than the other two Pygoscelis species.
Identification:
Gentoo Penguins are characterised by a white patch around and behind the eye that joins on the crown. The orange-red lower mandible is also a distinct feature. Two subspecies are recognised: a larger form in the sub-Antarctic and a smaller, but otherwise similar subspecies on the Antarctic Peninsula. Juveniles are very similar to adults, but the white eye-patch is not connected to their white eye-rings until they moult at an age of 14 months.
