北欧鸟类声音

This is one of the most comprehensive applications ever released about birdsounds of Northern Europe. Nearly 300 species, more than 2200 recordings and more than 40 years of work. Almost all of the high-quality sound samples are recorded by Jan-Erik Bruun and are now gathered into one easy-to-use application. In addition to frequently heard calls, the application contains more atypical and rarely audible sounds.
