Yearly, hundreds of thousands of albatrosses return to Halfway Atoll Nationwide Wildlife Refuge to their identical nesting web site—and reunite with the identical mate.

On this planet’s largest colony of albatrosses, Knowledge and her mate, Akeakamai, have been hatching and elevating chicks collectively since a minimum of 2012, when biologists first banded the male.

“At the very least 70 years previous, we consider Knowledge has had different mates,” mentioned U.S. Fish and Wildlife Service biologist Dr. Beth Flint. “Although albatross mate for all times, they could discover new companions if vital—in the event that they outlive their first mate.”

Albatross don’t sometimes lay eggs yearly and after they do, they lay solely a single egg.

Biologists estimate that Knowledge has hatched a minimum of 30–36 chicks in her lifetime. In actual fact, in 2018, biologists noticed the chick that she fledged in 2011 returning to the spot just some toes away from her present nest.

Virtually as wonderful as being a mother or father at 70 is the variety of miles Knowledge has flown—by the point she was 60 she’d logged a minimum of 2-3 million miles since she was first banded in 1956. That’s 4-6 journeys from the Earth to the Moon and again once more with loads of miles to spare.

One cause for all these frequent-flyer miles is that each Laysan albatross spends their first 3 to five years fledging at sea, by no means touching land.

“Annually that Knowledge returns, we be taught extra about how lengthy seabirds can stay and lift chicks,” mentioned Flint. “Her return not solely conjures up fowl lovers all over the place, however helps us higher perceive how we are able to defend these swish seabirds and the habitat they should survive into the long run.”

Albatross mother and father share incubation duties for 65 days and as soon as the chick hatches, they share feeding duties. Chicks fledge, and fly for the primary time, within the months of June and July.

To this point over 275,000 albatrosses have been banded on the Refuge. Thus, biologists could make extra knowledgeable administration selections that guarantee seabirds have the habitat and sources they want sooner or later.
