... frequencies. In general, owls were most sensitive to sounds originating in front of and above their heads, but at 8 kHz there was also an area of high sensitivity below the animals. Our results suggest that the directional hearing of saw-whet owls should allow for both predator and prey detection. megall...

... localization in air acted upon preexisting brain stem circuits like those in fishes. With movement onto land, the early tetrapods may have retained some sensitivity to particle motion, transduced by bone conduction, and later acquired new auditory papillae and tympanic hearing. Tympanic hearing arose...

These results suggest that small anurans can utilize nontympanic pathways for effective sound reception over a broad frequency range, whereas large anurans are more restricted to using a standard tympanic middle ear for hearing.

We argue that there have been strong selective pressures in most vertebrate groups for the sorts of sound encoding and processing abilities that result...
