Well you have to let the Tree know you’re a doctor so makes sense
An apple tree a day… Doctor comes.
I’m just going to pretend that’s one of the researchers from Where Oaken Hearts Do Gather.
I hear a palm-systolic murmur
doesn’t this actually happen to check something to do with sap?
If the sap sounds delicious
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.)
You could search for insects under the bark using the stethoscope, like woodpeckers do.
Wouldn’t the stethoscope have trouble actually bringing the sound to the ear pieces if the bark is as rough as in the image?
