The rate of bird migration over the Alps (up to a height of 150 m) was found to be highly comparable between fixed-beam radar measurements and visual bird counts, highlighting the potential use of this technique as an objective way of quantifying bird migration.
Observouse que a taxa de migración das aves sobre os Alpes (ata unha altura de 150 m) era moi comparable entre os datos medidos por radar de feixe fixo e os recontos feitos visualmente, destacando o uso potencial desta técnica como maneira obxectiva de cuantificar a migración das aves.
