What are Black-browed Albatross birthing rituals like?
Almost all Black-browed Albatross nesting sites are on cliff walls or edges with the exception of the nest sites on the Falklands which are located on flat coastal grasslands.
The breeding season varies a bit depending on where in the world a particular bird is located, but the season is generally held from late September through early November.
They are monogamous, pairing off for life.
One egg is laid. Both parents will take turns incubating the egg for about 70 days. Once hatched the chicks take another 4 months before they fledge (take their first flight).
Juveniles will return to the breeding colonies after about 3 years but usually this is just a dry run where they practice mating rituals; they usually won’t actually begin mating until they’re at least 7 years old.
