At roughy 7 pm on January 13th, almost 3 days after his mate had laid their egg, the male Cahow returned right on schedule.
They then spent the next several hours together until she headed out to sea leaving him to incubate their egg for the next few weeks whilst she regains her strength.
Once she returns they will alternate shorter shifts incubating the egg until if all goes well, after roughly 53 days, it hatches.
