Reindeer Cyclones are a real thing… a swirling mass of threatened reindeer stampeding in a circle making it impossible to target an individual.. here the fawns are in the middle

This herd is on Russia’s Kola Peninsula, in the Arctic Circle

Kann dem visuellen Eindruck aber nicht das Wasser reichen.

Und hier der Livestream:

This set of sounds from the surface of Mars were recorded by the microphone on the side of NASA’s Perseverance Rover on February 20, 2021. In the first set, sounds from the rover itself dominate. In the second set, the sound was filtered to make sounds from Mars more audible. You can hear a little wind in the second set.
This is the first time a Mars rover has been equipped with a microphone. The images in this video were taken by Perseverance’s Navigation Cameras, or Navcams, on the same day as the microphone sounds, Feb. 20, 2021.

Auf Olivier Messiaens Spuren – Alexander Liebermann hat sich der Gehörbildung gewidmet.

The Gray Wolf (Canis Lupus) is one of the most widely distributed land mammal species. They are socially gregarious animals, and much of their social behavior is accompanied by vocalizations. Wolf pups vocalize within hours of birth, and adult wolves‘ vocal repertoire is wide.

Studies have shown that their mean fundamental frequency ranges between 274-908 Hz (~C-Sharp4 to ~A-Sharp5), and that their famous long-range vocalization, the howl, is used to communicate information on individual identity and location. Among packs, howling serves to advertise territory ownership and occupation, thus minimizing contact among them.

During courtship, the male and female penguins trumpet loudly to each other, thus learning each other’s call (They recognize each other amidst breeding colonies that consist of up to 40,000 penguins because of their calls). Emperor penguins typically use both sides of their syrinx simultaneously, producing vocalizations using ‚two-voices‘. In the videos I have seen, calls of adult penguins mostly consisted of two-voice vocalizations using three different intervals: M2, m3, M3. In contrast, those of the chicks consisted of single voices outlining numerous intervals: m3, M3, P4, TT, P5, m6.
