“…originally a species of steppes, it is today a typical resident of wide, open agricultural areas; its typical land utilization is an open, cultivated landscape, with at least a few bushes, trees, border stones, poles, etc. ; preferred biotopes are older fallow lands as well as other extensive or unused habitats, such as filed borders, where arthropods are more plentiful (Meyer et al, 2007). according to baillie et al (2001) the corn bunting is a characteristic resident species of lowland arable farmland, largely dependent on cropped land.…”

The decline of ground-nesTing birds in The agrarian landscape of iTaly bruno Massa 1 & Tommaso La Mantia 2 Résumé.-Le déclin des oiseaux terrestres dans les paysages agricoles d'Italie.-les auteurs résument le statut historique et actuel de quelques oiseaux granivores liés à l'environnement agricole en italie, en l'occurrence l'alouette des champs (Alauda arvensis), l'alouette lulu (Lullula arborea), le cochevis huppé (Galerida cristata), l'alouette calandre (Melanocorypha calandra), l'alouette calandrelle (Calandrella brachydactyla) et le bruant proyer (Emberiza calandra). ils soulignent que l'alouette calandre (sédentaire) et l'alouette calandrelle (migratrice transaharienne) sont les espèces qui déclinent le plus, l'alouette des champs (à la fois sédentaire et migratrice partielle) décline moins tandis que le cochevis huppé (sédentaire), l'alouette lulu et le bruant proyer (tous deux à la fois sédentaires et migrateurs partiels) sont plus ou moins stables. Toutes ces espèces sont essentiellement associées à l'agriculture «extensive» pratiquée sur de grandes surfaces mais qui, en réalité, l'est de manière «intensive», ce que les auteurs tiennent pour être la raison principale du déclin de ces oiseaux. Les réformes de développement planifiées pour la période 2007-2013 apparaissent comme une opportunité à saisir pour résoudre quelques effets dangereux dus aux mesures appliquées dans la période précédente. les mesures agro-environnementales encourageant les agriculteurs à améliorer leurs terres de manière à fournir à la faune sauvage de la nourriture, des abris et des sites de reproduction, devraient être mieux subventionnées en accord avec l'importance des bénéfices offerts à l'environnement.summary.-authors summarize the historical and current status of some granivorous birds linked to agri-environments in italy, namely skylark (Alauda arvensis), Woodlark (Lullula arborea), crested lark (Galerida cristata), calandra lark (Melanocorypha calandra), short-toed lark (Calandrella brachydactyla) and corn bunting (Emberiza calandra), pointing out that the most declining species are calandra lark (sedentary) and short-toed lark (transaharian migrant), less skylark (sedentary and short-distance migrant), more or less stable crested lark (sedentary), Woodlark and corn bunting (both sedentary and shortdistance migrants); all of them are mainly associated with "extensive" agriculture, which is practised in wide farmlands, but actually with "intensive" methods, that authors consider the main cause of depletion of these birds. The rural development reforms planned for the 2007-2013 period appear to be an opportunity to resolve some environmentally harmful effects arisen from the measure application in the previous period; agri-environment measures, rewarding farmers improving farmland with land able to provide food, shelter and nesting sites for wildlife, should be more competitively funded and paid in accordance with the importance of the environmental benefits provided.in the last decades a very unusual decline of some spec...

“…For the corn bunting, we used data from a closely related bunting species of about the same size, Emberiza citrinella . These estimated territory sizes are in agreement with other studies for skylark (1.02–1.16 ha, Fischer et al ., ) and corn bunting (2.5–7.5 ha, Meyer et al ., ). For yellow wagtail and northern lapwing, we did not find a direct estimate for territory size.…”

“…Models dealing with changes in bird populations often lack the flexibility to alter the underlying structure of the landscape (such as local field sizes or agglomeration of fields) or the comparison of different landscape types (e.g., Whittingham et al, 2003;Meyer et al, 2007;Boatman et al, 2010;Gottschalk et al, 2010). This is needed because during their breeding season, birds as well as many other animals are central place foragers and depend on local heterogeneities.…”

Species ecology and the impacts of bioenergy crops: an assessment approach with four example farmland bird species

2014

The cultivation of energy crops can cause land-use conflicts, including loss of biodiversity in farmlands. In our study, we focus on farmland birds and analyse whether the impacts of such bioenergy activities differ for bird species with different ecology. We do this by comparing the impacts on four example species; skylark (Alauda arvensis), yellow wagtail (Motacilla flava), corn bunting (Miliaria calandra) and northern lapwing (Vanellus vanellus). We used a spatially explicit ecological model, which combines three simplified crop selection criteria (suitability for nesting, suitability for foraging, spatial heterogeneity) that differ between the selected species. We used the model to investigate change in breeding pair density between a baseline and several bioenergy scenarios that differ in intensity and spatial agglomeration. We subsequently simulated scenarios with potential positive habitat effects (maintenance of 10% set-aside or 10% alfalfa) as well as spatial effects (increased crop diversity and reduction of field size) as mitigation strategies to increase the breeding pair density. The four species responded to the bioenergy scenarios with a decrease in breeding pair density that can be divided into roughly three levels: strong (skylark), intermediate (yellow wagtail and corn bunting) and no response (northern lapwing). The intensity of the response depended on the bioenergy scenario. The decrease in breeding pair density under the least intensive bioenergy scenario could be fully mitigated for all the considered bird species through 10% set-aside. However, with increasing dominance or spatial agglomeration of a single energy crop (e.g., maize), impacts cannot or hardly be mitigated and the effectiveness of the mitigation strategies becomes increasingly more dependent on the ecological preferences of the bird species.

“…They worked mainly in ecology for natural area (Guisan and Zimmermann, 2000) with mechanistic models and also operational static models (Gontier et al, 2006) but few concerned farmland. Besides the Vegepop2 model for field boundary flora (see above Clergue et al, 2005), another model covering a species of farmland, the Corn Bunting deserves attention but remains relatively complex, needing spatial data (Meyer et al, 2007).…”
