I once did a smell experiment (naturally) where we had some straight peppermint scent, then diluted it by 10, then 100, and so on until it was something like 10,000x diluted. People had to say when they could no longer smell the scent, and the point was that a shark still would be able to.
you could do something similar with sounds: have a series of increasingly hard-to-hear sounds til you get to on that applies to, say, eagles but is beyond the ability of people.
have fun!

Don't forget the super sense of smell of a turkey vulture. I suppose you
could rig up something one snifgfs that has only a tiny amount of smelly
stuff, versus one with a whole lot to do a comparison. (And maybe one
with nothing to show an owl's non-existent sense of smell; there's a
reason they prey on skunks...)
Of course, you might not want the smell to be the exact one the vultures
are usually looking for.

Hi,
We are planning a birds exhibition and are trying to make interactive
features that help the visitors understand the superior senses that some
of these birds have. For instance, a barn owl can locate prey based upon
hearing and a golden eagle can see a mouse from over a mile away. Has
anyone been able to demonstrate how humans perceive such things and then
how birds perceive the same thing but better?
Thanks,
John Lor
