Habitat usage by birds in an open agricultural landscape in winter. – While a large number of studies have dealt with the ecology and habitat requirements of farmland birds during breeding time, much less is known about the use of farmland by birds during winter. In this study, we counted the birds on transects on ten habitat types during winter 2014/2015 in the Champagne genevoise, canton of Geneva, Switzerland. The study area (7,7 km2) is a largely open arable countryside. Since 1991, a regional project to enhance farmland biodiversity has led to the creation of numerous field margins and wildflower areas that have contributed to a significant increase of breeding bird numbers (e.g., Common Whitethroat Sylvia communis and European Stonechat Saxicola rubicola). We observed 1480 individuals from 37 bird species. Eurasian Skylark Alauda arvensis, Common Chaffinch Fringilla coelebs, and European Goldfinch Carduelis carduelis were the most common species. We found that the number of species per transect strongly depended on the month of visit (less species in November/December versus January), on the observer, and on the habitat type. Positive effects on species numbers were found for medium-sized vegetation (tall herbs and bushes) and especially if there were trees in the vicinity of a transect. Increased numbers of species were also found at field margins (an ecological compensation area type specific to the regional project), at wildflower areas (an optional measure of the Swiss agri-environment scheme), at ruderal areas and maize stubbles. Cereals, rape and meadows supported the smallest numbers of species. However, habitat requirements varied among species. For example, the set of species differed between intertillage crops and stubble fields; to enhance farmland bird communities during winter, a mosaic of habitats is thus recommended.
