I was mild hoping there was a birdnet pi image with all of the magic mostly done for something like this.
like the author I'd love to set this up for my mom and mother in law as they have the phone app but it's not as exciting unless you're sitting outside.
I recently completed a MSc with a focus on bird bioacoustics, and this problem goes for the whole ecosystem/pipeline: there are very few (non-proprietary) off-the-shelf, ready to go products. Even the most popular methods that are extolled in lots of papers and by NGOs all practically need a dev/data scientist for basic implementation
Both BirdNET-Pi and BirdNET-Go provide statistics pages with similar plots where you can choose birds and date ranges, but they are not as polished.
