Misandry, polyandry, whatever. I know it’s some kind of -andry. Hordeling Ron Sullivan and her partner in crime Joe Eaton have been spending a lot of time in the San Joaquin Valley of late, and Joe has a new post up on Ron’s blog riffing on their recent frequent sightings of Swainson’s hawks. It turns out that the hawks engage in behavior that completely undermines the traditional institution of marriage as Gahd intended:
Polyandry, it seems, is not that unusual in buteos and related hawks. It’s more or less standard for the Galapagos hawk, which genetic studies indicate is the Swainson’s closest relative. (The i’o or Hawai’ian hawk is also near kin. Swainson’s is typically a long-distance migrant, with most of the population traveling from the North American plains to the Argentine pampas every year. You can see how accidental colonization of remote islands might happen.) Polyandrous mating groups also occur in the more distantly related Harris’s hawk. The advantage? Male raptors often provide prey for their incubating mates and nestlings. A female with two male providers would have a better chance of successfully fledging her brood.
The MRAs were right all along: it’s all about the child support. How dare those ladyhawks go against biology? Don’t they understand about gathering berries?
Anyway, it’s a good post by a longtime favorite natural history writer. And the post title proves that Parentheses Matter.
Speaking of people writing good stuff at the Coyot.es Network, we’ve added two new blogs over there: “InyoOwnWay” by Owens Valley biologist Mike Prather and “Miracle or Mirage?” by renewable energy maven Patrick Donnelly-Shores. We’ve got another new addition pending once she answers her email.
