Washington, march 18 : While female birds are known to choose their mates based on fancy feathers, a new study suggests that female mammals are more likely to follow their noses to the right mate.
Cambridge zoologist Tim Clutton-Brock and Harvard researcher Katherine McAuliffe point out that it is generally thought that mate choice plays a smaller role in mammals than in birds because vivid examples of female preferences-such as the ornate tails of peacocks that emerged because peahens prefer to mate with males that have showy plumage-are harder to find in mammals.
However, they say, female mating preferences are likely to be just as important in mammals, though they may not be as obvious to human observers.
