One of the most famously monogamous species of birds may be driven to divorce their partners at higher rates as a result of a warming planet, a new study found.

Black-browed albatrosses have the reputation of mating for life and usually stick with one partner after pairing off. Usually, only 1% to 3% of albatross pairs split up and find new mates, according to The Guardian .

But that rose to as much as 8% during years of unusually warm water temperatures, according to researchers who analyzed data involving more than 15,000 albatross pairs in the Falkland Islands over a 15-year period. The study was published in the Royal Society journal this week.
