Two female penguins from the colony of the Antarctic area of the Oceanogràfic de València, Electra and Viola, have adopted the egg of another couple, incubated it and they have managed to raise a chicken.
Is the the first time a birth occurs under these circumstances at the Oceanogràfic, where this breeding season three chicks have been born in the colony of 25 Gentoo penguins (Pygoscelis papua), also known as Juanito.
The three couples that have raised chickens so far have been Navi and Aquela, Bolo and Melibea and a third made up of Electra and Viola and, although they are not many compared to other times, an unusual event has occurred, as reported by the Oceanogràfic it’s a statement.
Electra and Viola form an exceptional couple, although not unusual in the world of these birds, since the formation of same-sex pairs is common in more than 450 species of animals and occurs both in zoos and in nature.
The pair of the two females began, curiously, to have the usual attitude and actions prior to reproduction, how to build your own nest out of stones.
Reproduction, a thing of two
Observing this situation, the keepers decided to transfer a fertile egg from another pair and Electra and Viola successfully carried out the entire reproductive process and now have their first offspring.
The reproduction of penguins is at all times a thing of two: it begins with the construction of the nests that consist of a round pile of pebbles, which they lift with great care and care and which, depending on the circumstances, can reach 20 centimeters on each side.
The stones are a very precious commodity for these animals so, which is usually a matter of controversy, because their owners keep them at all costs and their defense can end in a dispute. In fact, the pebbles can be part of the courtship by the male.
The incubation is borne by the father and mother, which take turns every day and the eggs, normally two for each laying, hatch after 38 days and the chicks usually become independent at 75 days with an approximate weight of between 6 and 7 kilos.
