| Abstract | Predation has been suggested as an important factor affecting the success of breeding birds. Various studies have found that particular bird species either avoid or choose to breed in the proximity of predator nests. Here, we investigated whether the presence of a generalist predator, the Eurasian Kestrel, Falco tinnunculus, affects the breeding success of a passerine (House Sparrow, Passer domesticus), using an experimental design of nest box placement for the two species. No difference in breeding parameters was found with distance of House Sparrow nests from both active and inactive Kestrel nest boxes. However, whereas House Sparrows built nests and laid eggs in nest boxes both with and without active Kestrel nest boxes in the vicinity at a similar frequency, they laid more clutches, and the total number of eggs laid and young fledged during the breeding season was higher, in nest boxes located close to active Kestrel nest boxes than to inactive ones. Of the 367 House Sparrow nestlings banded, only 3 were found predated in Kestrel nests and no correlations were found between the percentage of birds in the Kestrels’ diet and breeding parameters of the House Sparrows. The proximity of breeding Kestrels may facilitate some protection to House Sparrows from other predators, such as corvids, which are chased away by Kestrels near the nest.Es wird angenommen, dass Prädation den Bruterfolg stark beeinflusst. Verschiedene Untersuchungen haben gezeigt, dass bestimmte Vogelarten entweder die Nähe von Nestern von Prädatoren vermeiden, oder explizit in deren direkter Umgebung brüten. In der hier vorliegenden Studie untersuchten wir. ob die Anwesenheit eines generalistischen Prädators, des Turmfalkens Falco tinnunculus den Bruterfolg einer Singvogelart, des Haussperlings Passer domesticus beeinflusst, wozu wir ein Experiment mit Nistkästen durchführten. Wir fanden keinen Unterschied in Brutparametern in Abhängigkeit von der Distanz von Sperlingsnestern zu sowohl besetzten wie unbesetzten Nistkästen von Turmfalken. Während Sperlinge mit gleicher Häufigkeit sowohl in der Nähe von aktiven wie inaktiven Nistkästen von Turmalken Nester bauten und Eier legten, hatten sie mehr Gelege, eine größere Anzahl Eier und mehr flügge Jungen in Nistkästen in der Nähe von besetzten Turmfalkennistkästen als in der Nähe unbesetzter Nistkästen. Von 367 beringten Haussperlingen wurden nur drei prädiert in Turmfalkennistkästen gefunden. Es bestand keine Korrelationen zwischen dem Anteil von Vögeln an der Ernährung der Falken und den Brutparametern der Haussperlinge. Die räumlich Nähe brütender Turmfalken könnte Haussperlinge vor anderen Prädatoren, wie zum Beispiel Rabenartige, welche von Turmfalken verjagt werden, schützen. |

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.
