Behavior
The gorfou of Snares nourishes mainly Krill, then of squid and fish. Sometimes it is able to see it perched on shrubs ( Olearia lyallii ).
Reproduction
The male turns over in the colonies to prepare the nest in August. It is built using stone and of wood, as well as vegetation. The female follows it can of time after and lays two eggs at the end of September/at the beginning of October. The first egg is not viable (of very rare case of success).
After having brooded egg during 10 days, the male leaves at sea for 12 days letting the female brood. On its return the female finally at sea leaves to nourish itself. The male broods in its turn until the blossoming which occurs between 37 and 39 days following the laying. The male then remains to keep and brood small still the 3 weeks during which the female makes return tickets between the sea and the nest to nourish chick by regurgitation.
At the end of these 3 weeks, the small one can autoréguler finally. It is then left with a crib. They are chick regroupings thus making it possible to increase the chances of survival of those.
Until the small one has 11 weeks, the parents will nourish it jointly. Once this period spent, the chick will take the sea and will return to reproduce only once reached the 6 years age.
