Nest site selection and territory distribution of Yellowhammer (Emberiza citrinella) and Whitethroat (Sylvia communis) in field margins.

Abstract

Territory maps and nest locations were used to assess habitat selection by breeding yellowhammers and whitethroats in relation to vegetation in field boundaries. Both species selected herbaceous vegetation for nest sites and occurred at higher densities where extensive, perennial, herbaceous vegetation was present in field boundaries.
