| Abstract | On the island of Cyprus the magpiePica pica, the hooded crowCorvus corone cornix, and the jackdawCorvus monedula have long been considered serious predators of gamebirds and pests of agriculture. They may be shot during the hunting season, but also during the nesting season, when birds and nests are shot for population control. The study confirms that old nests of magpies and hooded crows are used for nesting by the long-eared owlAsio otus, which is a rare resident breeder. The shooting of magpie and hooded crow nests in Cyprus has most probably contributed to the reduced numbers of breeding long-eared owls on Cyprus, and also to the reduction of the populations of other species such as the Cyprus scops owlOtus scops cyprius and the kestrelFalco tinnunculus, which also nest in old nests of Corvidae. The feeding habits of the magpies and jackdaws were investigated by examining 66 gizzards of magpies and 6 gizzards of jackdaws. The main items in their diet were grasshoppers and cicadas, followed by barley and wheat. No gamebird remains were found in any of the samples examined. It is suggested that the shooting of Corvidae during the breeding season should cease for the benefit of the rarer species using their nest for breeding, but also to comply with the European Union council directive 79/409/EEC, Article 7.4 on the conservation of wild birds.Auf Zypern wurden ElsternPica pica, NebelkrähenCorvus corone cornix und DohlenCorvus monedula lange als bedeutende Flugwild-Prädatoren und landwirtschaftliche Schädlinge betrachtet. Die Arten dürfen während der Jagdsaison erlegt werden, zusätzlich aber auch während der Brutzeit, wenn zur Bestandskontrolle Vögel abgeschossen und ihre Nester ausgeschossen werden. Die Untersuchung bestätigt, dass alte Elstern- und Nebelkrähen-Nester von der WaldohreuleAsio otus, einem seltenen Brutvogel, zum Nisten genutzt werden. Das Ausschie\en von Elstern- und Nebelkrähen-Nestern hat höchstwahrscheinlich zur Abnahme des Brutbestandes der Waldohreule auf Zypern beigetragen, ebenso zur Abnahme der Bestände anderer Arten, wie der zyprischen ZwergohreuleOtus scops cyprius und des TurmfalkenFalco tinnunculus, die gleichfalls alte Rabenvogelnester zum Brüten nutzen. Die Ernährungsgewohnheiten von Elstern und Dohlen wurden anhand der Auswertung von 66 (Elster) beziehungsweise 6 (Dohle) Mägen untersucht. Heuschrecken und Zikaden bildeten die Hauptbestandteile der Nahrung, gefolgt von Gerste und Weizen. überreste von Flugwild wurden in keiner der untersuchten Proben gefunden. Es wird vorgeschlagen, den Abschuss von Rabenvögeln während der Brutzeit einzustellen, um seltene Arten zu schützen, die Rabenvogelnester zum Brüten nutzen, und zur Einhaltung der Richtlinie 79/409/EWG, Artikel 7.4 des Rates der Europäischen Union über die Erhaltung der wild lebenden Vogelarten.Sur l'Île de Chypre, la Pie bavarde (Pica pica), la Corneille martelée (Corvus corone cornix) et le Choucas des tours (Corvus monedula) ont de tous temps été considérés comme de sérieux prédateurs d'oiseaux-gibier et comme des pestes pour l'agriculture. Ils peuvent être tirés pendant la saison de chasse et aussi durant la saison de nidification lorsque oiseaux et nids sont tirés en vue de contrÔler la population. L'étude confirme que d'anciens nids de pies et de corneilles sont utilisés pour la nidification par le Hibou moyen-duc (Asio otus), lequel est un nicheur sédentaire rare. Le tir de nids de la Pie bavarde et de la Corneille mantelée sur Chypre a plus que vraisemblablement contribué à la réduction du nombre de hiboux sur Chypre ainsi qu'à la réduction de populations d'autres espèces telles que le Hibou petit-duc (Otus scops cyprius) et le Faucon crécerelle (Falco tinnunculus) qui niche également dans d'anciens nids de Corvidés. Les habitudes alimentaires des pies et des choucas ont été examinés en analysant le gésier de 66 pies bavardes et de 6 choucas. Les éléments principaux rencontrés dans ces gésiers étaient constitués de sauterelles et de cigales suivis d'Orge et de Blé. Aucun reste d'oiseau-gibier n'a été trouvé dans aucun échantillon examiné. Il est suggéré qu'il soit mis fin au tir de Corvidés pendant la saison de reproduction, non seulement pour le bien des espèces rares qui adoptent leurs nids pour y nicher mais aussi par respect de la directive du Conseil de l'Union européenne 79/409/EEC, Article 7.4 sur la conservation des oiseaux sauvages. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
