Sex-ratio and body size of sandpiper chicks at Zackenberg, north-east Greenland in 2003
There is growing evidence that female birds may adaptively bias the sex ratio of their young as a function of environmental conditions. Data on brood sex ratio in shorebirds are scarce, however. In this study we report the brood sex ratios and morphometrics of Arctic sandpipers. Sex was determined i...
