Gentoo Penguins (Pygoscelis papua) nest in colonies adjacent to sandy or shingle beaches at over 80 locations around the Falklands.Two eggs of equal size are laid in late October, with birds re-laying if the first brood is lost. Chicks form into creches at 4 weeks of age, and fledge at 14 weeks in early February.Adults generally forage close to shore within 20km of the breeding site.
