I am developing a fictional species of raptor or raptor-like bird, with incredible senses, for a fantasy setting. One element of their combined sensory picture that I thought of was the use of sensory organs that detect vibration to an incredible degree, similar to seals underwater.
This means the ability to detect vibrations (or something similar if I'm using the wrong word) at great enough ranges and/or long enough after the signal producer is gone to be practical. Obviously the difference here is that these fictional raptors would be using air as the medium not seawater.
For the sake of the question assume the atmospheric composition is like that of earth, unless you need to change it slightly to make it plausible then by all means include that in your answer. Also, please ignore how the animals would interpret these senses, I am specifically interested in the mechanical plausibility. If necessary assume the raptors have a built-in filter for the clutter of air rushing past the sensory organs. I am not interested in answers involving sonar.
So, is this type of sense possible in any form in the air? If so, what is the method; whiskers, organic pitot tubes, something else? If it is only partially possible, such as at short ranges or under specific conditions or in specific circumstances, what would those be?
Thanks in advance!
EDIT: After having been made aware that hearing is based off of vibration, I want to clarify. I have seen tests where seals follow the path of submersible drones, after the drone had finished its course, whilst blindfolded. This was attributed to the seal's whiskers as a sort of touch sense, seperate from hearing. So would a similar thing work in air where for instance the fictional raptor might track aged signs of movement or does the atmospheric medium prevent this?
EDIT 2: One rough theory I have just brainstormed is as such. Given the correct biology, could these birds be able to feel turbulence in the air, such as after other birds pass by at a distance, and follow a path of turbulent air like a boats wake?
