This video is about an ortolan bunting singing.
From Bird Study:
A territory scale analysis of habitat preferences of the declining Ortolan Bunting Emberiza hortulana
02 Feb 2016
Capsule: Ortolan Bunting occurrence is associated with bare ground, lucerne, shrub cover and hedgerows/tree rows.
Methods: We mapped territories in ten different plots and built a habitat selection model comparing 52 occupied cells with 52 unoccupied ones (cell size: 1 ha). We built multivariate adaptive regression splines models based on ground-measured variables.
Results: The model revealed an association with intermediate Lucerne cover (50% of the cell), high shrub cover, bare ground (≥5%) and hedgerows/tree rows (≥25 m/ha). The most important driver of occurrence was bare ground (optimum at 5–20%).
Conclusion: The maintenance of the mosaic and low-intensity farmed landscape, the promotion of lucerne and the conservation/restoration of hedgerows/tree rows, may be promoted through the Rural Development Programme. The conservation of bare soil, grassland and shrubs at optimum amount at fine-scale could be the object of an agri-environment scheme targeted specifically at the Ortolan Bunting.
