Language eng - English Country CZ - Czech Republic Keywords migratory birds ; spring arrival ; North Atlantic Oscillation Subject RIV EG - Zoology R&D Projects KSK6005114 GA AV ČR - Academy of Sciences of the Czech Republic (AV ČR) Annotation Spring arrival dates of 37 migratory bird species recorded in Moravia (Czechland) during 103 years between 1881 and 2001 were correlated with seasonal North Atlantic Oscillation (NAO) index. Bird arrivals occurred significantly earlier following positive NAO values (causing a warmer spring than normal in Central Europe) in all short-distance migrants with a European/Mediterranean winter range (e.g., Alauda arvensis, Columba palumbus, Serinus serinus, Sturnus vulgaris, Turdus philomelos, Vanellus vanellus). However, the timing of arrival did not correlate significantly with NAO in long-distance migrants having largely a sub-Saharan winter range (e.g., Apus apus, Ciconia ciconia, Cuculus canorus, Hippolais icterina, Hirundo rustica, Oriolus oriolus, Streptopelia turtur, Upupa epops). The prevailing positive phase of winter NAO conditions observed in Europe at the end of the 20th century has obviously determined the trend of an earlier than normal arrival of short-distance migrants.
