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 […]
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 […]
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 […]
Effects of predation risk on diurnal mass dynamics and foraging routines of yellowhammers (Emberiza citrinella)
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 […]
Prey Handling in Yellow-crowned Night Herons
Yellow-crowned Night Heron (Nyctanassa violacea) Science Article 1 abstract Although an extensive literature exists on the foraging ecology of wading birds (reviewed by Kushlan 1978), detailed studies of the Yellow-crowned Night Heron (Nyctanassa violacea) are lacking.The yellowcrown is unique among the ardeids in that it specializeson crustacean prey (Palmer 1962, Hancock and Elliott 1978) and […]
Publishing LtdPhylogeny and biogeography of Yellow-headed andBlue-fronted Parrots (Amazona ochrocephalaandAmazona aestiva) with special reference to theSouth American taxa
Yellow-crowned Amazon (Amazona ochrocephala) Science Article 1 abstract The Yellow-headed Parrot (Amazona ochrocephala) has a broad Neotropical distribution,ranging from Mexico to the Amazon Basin, and a history of complex taxonomy and controversialspecies limits. Recent molecular analyses have started to clarify the taxonomicarrangement of the complex, but have not included a representative geographical samplingfrom South America. […]
Hidden leks in the Yellow-browed Warbler Phylloscopus inornatus? -Investigations from the Khan Khentey reserve (Mongolia)
Yellow-browed Warbler (Phylloscopus inornatus) Science Article 1 abstract The breeding biology of the Yellow-browed Warbler Phylloscopus inornatus islargely unknown. Recently the species was found to breed in clusters and somehypotheses on the function of aggregated breeding sites have been proposed.To obtain new insights, two clusters of Yellow-browed Warblers were observedfrom May to July 2003 in […]
