Las aves cambian sus fechas de migración en las últimas décadas

Resumen

[EN] For over 60 years, hundreds of volunteers have been recording the first day they saw
\nor heard a stork, a cuckoo, swift, swallow or nightingale in their towns, as well as the day they last saw them.
\nThe analysis of this information (over 44,000 records in almost 1,400 towns between 1944 and 2004) has permitted the assessment of the potential impact of recent climate change on the migratory habits of birds on the Iberian Peninsula. The nightingale is the only species that has not changed its arrival date in the course of the last six decades.
