Eloisa Matheu and Francesc Llimona, biologists, created in 1992 the label Alosa, nature sounds, to publish guidelines for consultation sound of the songs of birds in Spain, at a public thinking ornithological and naturalist, covering a gap in the reference material. Then incorporate the collection of soundscapes. What in 1986 started as a hobby grew into a vocation.

Currently our catalogue includes reference guides to birds, amphibians, mammals and insects, various publications in collaboration with agencies or publishers and bird guides published in Europe.

Currently we are working on recording songs and vocalizations of new species as well as soundscapes.

The dissemination of knowledge and sound of nature is one of our main objectives, which are defined in collaboration with scientific papers and conducting workshops of identification by ear and nature sounds auditions. More information about workshops in section News > Activities.
