Climate Change Is Making Birds SluttierKatie J.M.

Scientists used to think that the majority of birds were monogamous, but we now know that most "cheat" on their "spouses" and that global warming exacerbates the trend: researchers found that females in unstable climates lay more eggs that lack their spouse's DNA and swap mates more often between breeding.Researchers also discovered that female birds are more likely to stray if their male spouses aren't bringing enough to the table. "A tern that brings plenty of fish back to the nest one season may not be able to find any fish the next, prompting his mate to seek out a better partner," according to the study. (Hey, did these bird-ladies read my post earlier today on marriage as "luxury"?!?) Some really harsh birds will drop a beau if he's not looking too fly, and formerly-pretty males can lose their shiny plumage if weather conditions are bad.
