Ortolan buntings, new study


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

Abstract

Capsule: Ortolan Bunting occurrence is associated with bare ground, lucerne, shrub cover and hedgerows/tree rows.

Aims: To assess the habitat features selected by Ortolan Buntings at the territory level in semi-open landscapes, in the northern Apennines of Italy.

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.
