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.”

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
