Albatrosses Create Two-Mommy Families

laal.jpg Males in short supply? Or unreliable? Well, two mommies will do just fine. Laysan albatrosses in Hawaii employ a strategy called reciprocity, whereby unrelated females pair together and take turns raising offspring. On the island of Oahu, where 59% of the albatross population is female, fully 31% of the nests are female-female pairs. And though they raise fewer chicks than male-female pairs, given the shortage of males, fewer chicks are better than none. Plus, because albatross can raise only one chick a year, the females stay together in monogamous couples for years, allowing both females the opportunity to reproduce.

The findings, by University of Hawaii at Manoa zoology doctoral candidate Lindsay Young and coauthors BJ Zaun and EA VanderWerf, are published today in the Royal Society journal Biology Letters, in the paper “Successful same-sex pairing in Laysan albatross.”

THE BIG PICTURE

You expect the big picture, and it's our job at Mother Jones to give it to you. And right now, so many of the troubles we face are the making not of a virus, but of the quest for profit, political or economic (and not just from the man in the White House who could have offered leadership and comfort but instead gave us bleach).

In "News Is Just Like Waste Management," we unpack what the coronavirus crisis has meant for journalism, including Mother Jones’, and how we can rise to the challenge. If you're able to, this is a critical moment to support our nonprofit journalism with a donation: We've scoured our budget and made the cuts we can without impairing our mission, and we hope to raise $400,000 from our community of online readers to help keep our big reporting projects going because this extraordinary pandemic-plus-election year is no time to pull back.
