[email protected] YELLOWHAMMER (Emberiza citrinella) ECOLOGY IN AN INTENSIVE PASTORAL DOMINATED FARMING LANDSCAPE DAWN E. ANDERSON Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy Institute of Biodiversity, Animal Health and Comparative Medicine College of Medical, Veterinary and Life Sciences University of Glasgow October 2013 2 Abstract Farmland birds in Europe have declined as agriculture has intensified, with granivorous specialists disproportionately affected. Despite grassland based farming being widespread, farmland bird research to date has focussed on mixed and arable farms. Yellowhammers are a red-listed species in the UK. This study investigated year round habitat requirements, diet, and movements of yellowhammers at four grassland dominated farms in Ayrshire, Scotland. Data were obtained via field surveys and trials, radio-tracking and faecal analysis. Fine scale breeding season foraging habitat requirements were studied by comparing invertebrate and vegetation communities at foraging sites with paired controls across all four farms.
