About me

About me

Stanislas Wroza


I’ve been fascinated by wildlife since I was 10. It all began with emblematic mountain species such as black grouse, capercaille, big mammals or mustelids and quickly extended to raptors, passerines, shorebirds and finally gulls.

I’m primarily interested in birds of Europe and North America but also reptiles, amphibians, mammals, odonates and butterflies. From the very beginning, I have always had an inclination for sounds, but only In December 2016 did I finally take the next step and decide to focus mainly on the sound approach. Since then, I am always on the field with my microphone (Sennheiser ME 66 + Olympus LS-12), looking for new sounds and amazed at how much there remains to learn.

In my professional life, I’m working on the management of natural areas for the French ministry of Environment.

You can listen to some of my recordings here.

  1. Bonjour Stanislas, pour une recherche sur les Bondrée nicheuse en forêt de Rosny et à Moisson nous n’avons pas trouvé d’enregistrement des cris de jeunes Buses et de Bondrées .étonnant non!!!.

    1. Bonjour Laurence,

      On trouve quelques cris de jeunes buses et bondrées au nid ici :

      Buse variable :

      Bondrée apivore

      En espérant que ça puisse t’être utile


  2. Hello Stanislas,

    I found your great recording of the European Bee-eater on Xeno-canto. I’m wondering if I may use this audio for an independent doku that I’m making about the Fire Salamander and the Bsal plague? There’s a scene that takes place in Croatia and this would be great to include.

  3. Actually, can you answer me a question, Stan? I recently bought a secondhand Olympus LS12 and I try to keep it with me at all times, in order to catch unexpected noises and birdsong . . .the one that pops up just when you weren’t expecting it. But the big problem is wind noise on the small microphones. It looks like I have to pay at least 30 Euro for one of these professional wind mufflers. Is there any trick for doing this cheaper?

    1. Hi Peter,

      Yes, you need to put some kind of “windscreen” on the mics in order to avoid wind noise. Don’t buy 30 euros windmufflers ! Just cut and roll some old socks/tights or even a piece of sponge around the mics and this will do exactly the same effect as “professional” wind mufflers.


  4. Bonjour Stanislas,

    It´s an really amazing project you are running here, thanks for sharing! 🙂
    I´m currently working for an environmentalist project and I wonder if it would be possible to use some of your sounds for it with a CC BY-SA 3.0 license?

  6. Only just discovered your excellent website, while looking help with autumn Chiffchaff calls. I wish all experts could write and explain as clearly as you do. Thank you.

  7. Bonjour.
    Excellent ton livre “Les Oiseaux par le son”. Ça ouvre de nouvelles pistes pour identifier, notamment pour des gens de mon age (66 ans) qui ont une audition qui se dégrade dans les aigus. ma limite est 8 000hz. Les chants des Roitelets deviennent inaudibles, ça me désole. Les sonagrammes dans les années 80 étaient tellement difficiles à obtenir, il fallait pouvoir utiliser l’appareil à la fac, pas toujours disponible, venir avec les bandes, le magnéto…C’est si facile d’en générer soi-même maintenant !
    A quand une sorte de base de données avec ces sonagrammes. J’imagine bien l’avenir aussi à la manière des logiciels dont dispose la police pour comparer les empreintes digitales. En quelques minutes, avoir une correspondance de l’oiseau recherché en comparant aux fichiers stockés dans une base. Juste après la lecture de ton livre, j’ai placé un AudioMoth dans le jardin cette nuit et j’ai des cris, certains non identifiés pour l’instant mais aussi une alarme de femelle Hulotte à 2h00 du matin. Génial!
    Merci à toi.

  8. Stan, hello from Australia. I am so happy I discovered your web site. I am a beginner bird sound recordists and your informative and easy to follow site has been so helpful and has taught me a lot about sounds. Thank you

  9. Hi Stanislas,
    I saw your incredible amount and highest quality recordings. This summer, before the Covid-19 I meant to go to Lake Baikal for birdwatching and sound recording. It might be realized one day. Beforehand I would like to familiarize myself with all the possible bird sounds for for the area. Unfortunately the sounds of 2-beautiful buntings are not downloadable from Xeno-Canto. The birds in question are Yellow-breasted & Chestnut Buntings. Would you be able to open them up for me? Please advise.

  10. Bonjour M. Wroza et bravo pour vos ouvrages que je viens d’acheter, c’est vraiment très motivant. Existe-t-il une possibilité de télécharger l’ensemble des sons de “identifier les oiseaux migrateurs par le son” en une seule fois sans avoir à flasher chaque QR code ?

    Bien cordialement


  11. Bonjour Stanislas, je cherchais votre adresse email sur le site Faune IDF mais impossible de la trouver, elle n’est pas affichée. Je suis un ornitho amateur et de la LPO et suis intéressé par votre obs du Pouillot à grands sourcils. Pourriez-vous me préciser dans quelle zone du bras mort de Seine exactement vous l’avez observé? Merci par avance si vous pouvez me répondre sur mon mail. Bien cordialement Marc

  12. Hi, very nice website and learning to get sounds from birds etc.
    How about the Low block filters (or high pass filters). Do you often use them?

    I?’ve got the option on my mic for 40Khz low block, and even in my recording device a block 20/40 etc. etc. to 220 KHz block filter.

    Is it handy to use?>

    1. Hi, almost all bird sounds are above 220 Hz. The sounds below 220 Hz are mostly motor sounds that you don’t want to record, so I always put the maximum High pass filter (in your case 220 Hz is fine)
