Nature: Polyandry Mr. Mom

Spotted sandpipers practice a mating system known as polyandry, where the female raises more than one clutch with different mates and the male is in charge of incubation and broodrearing. Terry Thomas is a wildlife biologist with 28 years of experience. Opinions expressed are his own. “The Best of Nature,” a collection of more than 100 of Thomas’s best nature essays is now available. Pick up your copy at the Post Register or order one through his website, www.nature-track.com.

There is one fight for mating dominance I would like to witness. By all accounts, it is a bloody, eye-gouging, biting, leg-busting, winner-take-all fight.
