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 […]

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 […]

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 […]

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 […]

Different migration strategies used by two inland wader species during autumn migration, case of Wood Sandpiper Tringa glareola and Common Snipe Gallinago gallinago

Wood Sandpiper (Tringa glareola) Science Article 2 abstract Waders generally follow two alternative strategies.The ‘B-strategy’ or ‘energy minimization’ strategy is to initiate migration late in the season, start moulting at the breeding grounds and migrate slowly in small steps, whereas the ‘S-strategy’ or ‘time minimization’istomigrateimmediatelyaftertheendofthebreedingperiodandmoulton the wintering grounds after a migration with only a few […]

Trap response of Wood Sandpipers Tringa glareola.

Wood Sandpiper (Tringa glareola) Science Article 3 abstract We used sightings and recaptures of colour-markedWood Sandpipers to examine the trapresponse of this locally abundant migrant in north-east Austria. Birds were caught in selectedwastewater pools of the local sugar factory using walk-in traps. According toresightings and recaptures, most birds apparently left the initial trapping site soon […]

Genetically confirmed interbreeding between western Bonelli’s warbler ( Phylloscopus bonelli ) and wood warbler ( P. sibilatrix )

Wood Warbler (Phylloscopus sibilatrix) Science Article 1 abstract During May and June 2003, a mixed breeding pair consisting of a male western Bonelli’s warbler (Phylloscopus bonelli) and a female wood warbler (P. sibilatrix) successfully raised six young in a broad-leafed forest near Junkerath, western Germany, an area far outside the regular breeding range of P.
