It has always been known that when we go out into the field to see birds it is almost as important to see them than to hear them. Of all the fauna that we can spot, birds are the group with which it is most important to have the ear attentive. Certainly most of the times we hear the bird before we see it. And unlike mammals, or even reptiles, that a broth can rebel their presence, in birds, is their voice.
Hear and identify which species is a call or song is basically a matter of continued practice and effort during our field days to reduce mistakes and confusions. But for a few years now, with the help of new techniques, we have greatly expanded our knowledge of the sounds made by birds and we have been given new material and new sources of information to make much more useful this aspect, which is so characteristic of birds.
Stanislas Wroza has been one of the most influential ornithologists to help popularize these new techniques, both with the publication of books and manuals and with a febrile activity recording, analysing and publishing sounds of many species in different platforms and websites on the Internet.
At the next Delta Birding Festival we’ll have the opportunity to listen to him by detailing all the advantages of making recordings on our field trips to observe birds.
