| Résumé : | The population of Rock Buntings along the river Main was surveyed systematically at Homburg (Kallmuth) and upstream from Karlstadt (Kalbenstein) to Veitshochheim (near Wurzburg).Rock Buntings were detected in the following five areas:Homburg, Kallmuth: 7 territorial male Karlstadt,NSG Kalbenstein: 6 territorial maleKarlstadt, Stettener Weinberge: 7 territorial maleThungersheim, Benediktenberg: 8 territorial maleVeitshochheim, Rabensberg: 4 territorial maleTotal 32 territorial maleThe number of Rock Buntings between Karlstadt and Veitshochheim, had developed positively from 19 (surveyed in 2009) to 25 male. The high population density of 7 Rock Buntings at the Kallmuth along and above only 1150 m of the vineyard lane in steep, rocky limestone habitat is remarkable, with one territorial male every 170 m or so. Five of these Rock Buntings were colour-ringed; two unringed males were also found. The steep limestone area at Kallmuth appears ideal for Rock Buntings. The area at Thungersheim-Benediktenberg seems to be similarly suitable. Eight territorial male were found there, of which two were colour-ringed and a third had been ringed in 2008. An area at foot of the rocky, shell limestone hillside, cleared of dense scrub in 2009 (see Schuphan 2011c, Figs. 2 and 3) had already been accepted as a Rock Bunting territory in 2011. Many other habitats are too densely scrubbed over for Rock Buntings. Clearance of these areas and their return / conversion to vineyards would be a durable, most effective and cost saving possibility to settle or repatriate Rock Buntings at the river Main. |
