I doubt it would actually be a stethoscope then though. Maybe something to gather the sap or to see below the bark but a stethoscope wouldn’t help with that. (I’m not a biologist but I know that stethoscopes are used to make it easier to listen to things and likely require a proper contact which one wouldn’t get on bark.)
doesn’t this actually happen to check something to do with sap?
If the sap sounds delicious

You could search for insects under the bark using the stethoscope, like woodpeckers do.
