Abstract
We assessed whether the sex ratio of nestling Marsh Tits (Poecile palustris) varied with habitat fragmentation by sampling broods from two British woodland areas with contrasting patch size, and comparing the data with published results from an extensive forest in Poland. We found no evidence for manipulation of offspring sex ratios, supporting findings from Poland, and suggesting that this trait may be typical of the species. The results are important in helping to understand the origin of biased sex ratios observed among adult Marsh Tits in the declining population in Britain.
