Yellowhammer (Emberiza citrinella) Science Article 6 abstract Theoretical models predict that when having fat reserves is costly in terms of predation risk, birds should decrease their levels of fat reserves in response to increased predation risk. I performed an experiment in which yellowhammers were exposed to a control treatment, where a curtain was moved several […]

Use of field margins by foraging yellowhammers Emberiza citrinella
Yellowhammer (Emberiza citrinella) Science Article 3 abstract Some agri-environment schemes promote the creation and management of a variety of non-crop habitats on farmland inthe UK, yet there has been relatively little monitoring to assess how species, particularly birds, use these habitats. The presentstudy deals with a declining UK farmland bird species, yellowhammer Emberiza citrinella, and […]
Foraging habitat selection by yellowhammers (Emberiza citrinella)nesting in agriculturally contrasting regions in lowland England
Yellowhammer (Emberiza citrinella) Science Article 2 abstract Fine-scale habitat use by yellowhammers (Emberiza citrinella) searching for food to provision nestlings was compared in threeagriculturally contrasting regions of lowland England. Log-linear modelling was used to test for signi?cant overall variation inhabitat use and signi?cant di?erences in relative use between pairs of habitats. Yellowhammers provisioned nestlings non-randomlywith […]
Indirect effects of pesticides on breeding yellowhammer(Emberiza citrinella)
Yellowhammer (Emberiza citrinella) Science Article 4 abstract Intensification of agriculture is believed to have caused declines in farmland bird populations. One of the key elements ofrecent agricultural intensification is the increased use of pesticides. However, studies elucidating relationships betweenindividual management practices and responses in bird populations remain rare. Here, evidence is presented of indirect effects […]
Interspecific feeding of a Great Grey Shrike (Lanius excubitor) fledgling by adult Yellowhammers (Emberiza citrinella)
Yellowhammer (Emberiza citrinella) Science Article 1 abstract On 25 May 2003, near the village Budy (Biebrza Marshes, East Poland), interspecific feedingof a Great Grey Shrike (Lanius excubitor) fledgling by adult Yellowhammers (Emberiza citrinella) wasobserved.

Habitat selection by yellowhammers Emberiza citrinella on lowland farmland at two spatial scales: implications for conservation management
Yellowhammer (Emberiza citrinella) Science Article 5 abstract Yellowhammer Emberiza citrinella populations have declined rapidly in the UK over recent decades, and a clear understanding of their habitat requirements is important to help inform conservation schemes. We aimed to disentangle and rank the effects of winter versus breeding season habitat characteristics. 2. We used information theoretic […]
