The penguins are monogamous?

A TYPE habit. But penguins are not traditionally considered monogamous? On average, 72% of these birds do return year after year to the same mating site, to find the same partner. This behavior, known as nest site fidelity (a kind of fidelity to the love nest, rather than his companion), provides that it is the male to come back in the same place, hoping to cross, in the few weeks where you will stay, the "wife".

SHORT BUT INTENSE. For several species, marital idyll lasts about three weeks around the end of October, just in time of the mating season. After everyone returns to swim on their own. But things do not always go smoothly, and when the "divorce" penguins is often more for logistical reasons and to issues of betrayal.

SINCRONIZZIAMOCI. It may happen that a penguin back to the nest to find the female with another partner, but it only happens in 26% of cases of "separation." More often now, the two partners do return home at slightly different times, to find that the companion or the companion there or has moved.

EXCHANGE OF FAVORS. The less predictable in this game of expectations and arrivals seem to be just the female penguin, among which is also documented opportunistic behavior, by offering sexual favors for as long single males that these help them to collect stones for the nest . Often, once they obtain their goal, females are fleeing not complete the pairing.
