Swan wing sound
The sound made by wings of a flying swan can be heard up to a kilometer away. Apparently swans also use this for communication.
This swan was spotted on 09. august 2024 at Panga on the island of Saaremaa, Estonia. We first heard the sound, then saw the bird, and had enough time to grab the camera and start recording.
Recorded with Canon EOS R10 and the 18-140mm STM lens. Image stabilized and sound processed (reduction of wind noise, dynamics compression) in DaVinci Resolve.
