摘要: In semi-arid ecosystems, rainfall and temperature induce changes in the food chain affect breeding conditions of raptors. We examined influence on success Eurasian Kestrel Falco tinnunculus inhabiting xerophytic scrub Tenerife Island, Canary Archipelago. Reproductive performance was recorded during five years, availability (arthropods, lizards, mice birds) monitored monthly a wet dry season. found that increased previous autumn associated with an earlier laying date more prolonged Mean clutch size showed positive correlation month prior to laying. Hatching fledgling did not vary significantly between year. Temperature parameters. Despite advanced larger observed, high prey egg formation year result higher overall b...
