The oldest identified wild fowl on the earth has laid an egg on the ripe age of about 74, her first in 4 years, US wildlife officers stated.

Knowledge and her mate, Akeakamai, had returned to the atoll within the Pacific Ocean to put and hatch eggs since 2006.
Laysan albatrosses mate for all times and lay one egg per 12 months. However Akeakamai has not been seen for a number of years and Knowledge started interacting with one other male when she returned final week, officers stated.
“We’re optimistic that the egg will hatch,” Jonathan Plissner, supervisory wildlife biologist at Halfway Atoll Nationwide Wildlife Refuge stated in an announcement. Yearly, hundreds of thousands of seabirds return to the refuge to nest and lift their younger.
Albatross dad and mom take turns incubating an egg for about seven months.
Chicks fly out to sea about 5 to 6 months after hatching.
They spend most of their lives flying over the ocean and feeding on squid and fish eggs.
Knowledge was first banded as an grownup in 1956 and has raised as many as 30 chicks, Plissner stated.
The everyday lifespan of a Laysan albatross is 68 years, in accordance with the Nationwide Oceanic and Atmospheric Administration.
