The occurrence ofOrtolan Bunting, a declining species in Europe,was investigated in relation to environmental characteristics of agricultural landscapes in Central Italy. The present work evaluated the significance of landscape features, land-use composition and crop type at the 7-ha scale, in predicting the presence of the Ortolan Bunting. The presence of the species was not strongly linked with measures of habitat heterogeneity, but was related to certain crop types: sunflower, oats and alfalfa, and also to the availability of bare soil. Patches of bare soilmay be characteristic for important foraging sites of the focal species.

Abstract

The occurrence ofOrtolan Bunting, a declining species in Europe,was investigated in relation to environmental characteristics of agricultural landscapes in Central Italy. The present work evaluated the significance of landscape features, land-use composition and crop type at the 7-ha scale, in predicting the presence of the Ortolan Bunting. The presence of the species was not strongly linked with measures of habitat heterogeneity, but was related to certain crop types: sunflower, oats and alfalfa, and also to the availability of bare soil. Patches of bare soilmay be characteristic for important foraging sites of the focal species. These results may help to predict Ortolan Bunting responses to changes in farming practices, and improve farmlandmanagement for themaintenance of the Ortolan Bunting populations in Italy.
