Warden cannot detect flying mobs unlike the sculk sensor

When experimenting with the warden, I noticed that it couldn't detect flying mobs like bats, parrots, and allays unless they hit the ground. This goes against the sculk sensor as it could detect those flying mobs in flight.

A way to replicate this is to spawn a warden in an enclosed room with wool at the bottom. After that, spawn a mob that flies like a bat or an allay. You will see that the warden cannot detect them through vibrations and will only notice them from sniffing. Do this again but with a sculk sensor and you will see that constant vibrations will be sent to the sensor as it can detect the flying mobs.
