| Size does matter when choosing a mate (573 words) |
| The difference in size between males and females of the same species is all down to the battle for a mate, according to a study of shorebirds published by British scientists today (August 9 2004). |
| Rensch's rule, as it has become known, says that the ratio between the sizes of the sexes is related to body size with very few exceptions throughout the animal kingdom - for example, male gorillas are much bigger than female gorillas, whereas male rats are only slightly larger than female rats. |
| Shorebirds, gulls and auks are the ideal group to test theories explaining Rensch's rule as the body mass of male shorebirds ranges from 59 per cent to 169 per cent of female body mass, encompassing nearly the entire range exhibited by the world's 9,700 species of birds. |
