A spectrogram of the soundscape of Mount Rainier National Park in the United States. Highlighted areas show marmot, bird, insect and aircraft noises. Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial.
Acoustic harassment and acoustic deterrents are technologies used to keep animals [1] and in some cases humans away from an area. Applications of the technology are used to keep marine mammals away from aquaculture facilities and to keep birds away from certain areas (for instance in the vicinity of airports and blueberry fields).
Many birds, especially those that nest in cavities, are known to produce a snakelike hissing sound that may help deter predators at close range. [ 44 ] Some cave-dwelling species, including the oilbird [ 45 ] and swiftlets ( Collocalia and Aerodramus species), [ 46 ] use audible sound (with the majority of sonic location occurring between 2 and ...
Mobbing can also be used to obtain food, by driving larger birds and mammals away from a food source, or by harassing a bird with food. One bird might distract while others quickly steal food. Scavenging birds such as gulls frequently use this technique to steal food from humans nearby. A flock of birds might drive a powerful animal away from food.
The sounds, referred to as a “Sonic Net,” do not have to be loud and are a combination of wave forms - collectively called "colored" noise - forming non-constructive and constructive interference with how birds and other animals such as deer talk to each other.
Now NASA is stepping in to provide some insight into what could actually be causing this scary pattern. NASA scientists believe the ominous noises could potentially be the "background noise" of ...
The phenomenon can last from just a few seconds to 45 minutes, sometimes involving tens of thousands of individual birds. In Ireland, starlings’ numbers are boosted during winter, as migrating ...
As they're arguing, several blocks down, it sounds like a shooting takes place, and he goes back to his car and just speeds away. Image credits: Sufficient-Berry-827 #14
