   Linear dimensions (mm) of female, intermediate (fæder) and male Ruffs, respectively, all measured by Joop Jukema. The material on females and males was all collected during the spring migrations of 2002 and 2003. All birds, except one fæder of 1 year old, were adult.

   The fraction of fæders was estimated in five morphometric data sets that were collected over four decades in four different countries in three different seasons (comprising 9133 Ruffs). The regression of fæder–female fractions was tested against the null model assuming that the number of fæders is 1.0% of females.

   The survival costs to fæders linked to the use of sub-optimal habitats as a result of competition from their larger counterparts may be compensated by higher breeding success.

   As females are a third smaller than males, most birds could easily be assigned a sex, while the fæders, female-mimicking males, were discriminated using wing length (Jukema and Piersma 2006).
