Abstract
Recent years have seen an increase in the number of publications on bat migration and an overall growing interest among bat researchers that culminated in the 1st International Symposium on Bat Migration in Berlin in January 2009. Here, we summarize the most recent findings about the biology and behavior of migratory bats and the phenomenon of bat migration, discuss the methods that were used to obtain them, draw attention to the challenges that migratory bats face in our changing world, and provide a few suggestions that may encourage researchers to conduct further work in this promising field.
