Three Guys For Every Girl— Why Male Polar Bears Have A Tough Time Getting A Date
Posted on Wednesday, February 05, 2014 by eNature
So what’s the best place for a male Polar Bear to meet a potential mate?
The experts recommend going to a prime seal-hunting spot. But finding such a spot is only the beginning of the challenge.
Nature Doesn’t Make It Easy
One reason a male Polar Bear must work overtime for a date is that females of the species don’t breed every year or even every other year. A female Polar Bear usually breeds only once every three years, which means that males outnumber eligible females three-to-one at the start of breeding season in the spring.
So competition for female attention is fierce, and males must fight one another, sometimes viciously, for the privilege of mating.
The Girls Can Play Hard To Get
Further complicating matters is the fact that female Polar Bears enjoy a good chase and will lead pursuing males across the ice for miles and miles.
In some cases, a chase can cover more than sixty miles—not for the timid or the weak of heart.
And we all thought it was tough to get a date to the Prom!
Without the vibrant color of a cardinal or the sweet song of a sparrow, how does a seabird go about attracting its mate? Here.
St Valentine’s Day is traditionally the time when birds start to choose their mates, with egg-laying for most resident species commencing in March or April. For a handful of birds, including Tawny Owl, Mistle Thrush and Dipper, nesting may already be under way in February, but numbers of these three early breeders are falling rapidly, according to the British Trust for Ornithology’s (BTO) BirdTrends report, published on-line today: here.
The secret of how the polar bear copes with a high-fat diet without getting a heart attack can be found in the creature’s genetic makeup according to scientists who have analysed the genome of the world’s greatest living land predator: here.
