Spring migration characteristics of the House Martin, Delichon urbica (Aves: Hirundinidae) in Croatia: A rasponse to climate change?

Many authors have discussed use of birds (and other organisms) as sensitive biomonitors for climate change. In this paper we investigate the long–terms trends in first arrival dates of long–distance migratory House Martin Delichon urbica (Linneus 1758), in norh-western Croatia during the 28-year period. The aim of this paper is to identify possible relationship between arrival times and local spring air temperatures. Between 1981 and 2008 the House Martin arrived progressively earlier (5.9 days), probably in response to climate change. First arrival dates correlated significantly with increasing March–April mean temperatures. Correlation between mean air spring temperature and year were also statistically significant. Our result suggests that arrival timing of the House Martin is influenced by spring air temperatures.
