Re: animal sound localization

owls are passive locators - so be sure you differentiate between these two mechanisms.

... and you are asking about scientific examples of such. FYI - There are observations of large whales doing things - like counter-calling over long distances and then joining up - that seem to have an explanation in this domain. Some of these have been scientifically validated by playback experiments, but these are not able to test vertical acuity. Whales also find food resources through either active or passive acoustic localization in 3-space.

Are there any examples of an animal (besides a dolphin) who can localize
sound sources in the vertical plane with the same (or similar or better)
acuity as the horizontal plane?

Are there any references to such a finding?

Thank you in advance.
