Relationship between spring migration, temperature and year in the Common Starling Sturnus vulgaris
Zdravko Dolenec
Sažetak
The global average temperature has increased over the past 100
years, and the climate change has produced many responses in the
plants, animals and the whole ecosystems. Numerous researches have discussed about the use of birds (and other organisms) as sensitive biomonitors for warm springs. I have been examining long-term trends of spring arrival in a population of Common Starling Sturnus vulgaris studied during 34 years in order to document patterns of its temporal variation and relationships to local spring temperatures. Common Starling is a short-distance migrant, wintering in the Mediterranean region (southwest Europe and northwest Africa). Many works from different areas have devoted attention to the negative correlation between the dates of spring migration and year, and the negative correlation between the
dates of spring migration and air spring temperatures. In this study,
the correlation between mean spring air temperatures and arrival date was not significant. Furthermore, the relationship between mean spring air temperatures and year was not significant either. Moreover, no significant correlation between arrival date and the entire research period (1980–2013) was detected.
