I've been watching my neighborhood birds for a while now and they indeed have individual personalities. It's pretty cool to know for example when a neighborhood cat is approaching, how it's approaching (stalking or walking?), and even which cat it is all because the birds communicate it to each other.
Wow, so cool to see someone reference Jon Young on HN.
I was about 12 or so when was gifted a copy (is that an appropriate term for a cassette pack?) of Seeing Through Native Eyes[0], which I devoured. That led me to his book Advanced Bird Language[1], which blew my adolescent mind. I still have both, and a lot of the material has really stuck with me.
One of the organizers wrote the BirdNET app... Improvements can help both the app and a lot of passive ecosystem monitoring projects. It's also a great excuse to listen to birdsong!
I am interested in bird watching as a hobby. An "unfortunate" but intrinsic aspect of it is that since bird species varies between continents, some knowledge is less applicable. When I bought my first book about bird songs in English I did not realize that, it mostly mentioned American species that are not present in Europe. I did not learn much applicable knowledge from it.
Another example, in the /r/birding subreddit people are mainly discussing about American birds.
Obviously, this is natural and nothing to really complain about. But it often requires to "read between the lines" to understand the location context in a discussion, especially when you are new.
The Sound Approach to Birding is a bit more European. (it was my first book on bird song, though I live in the US... So I feel your pain.) It has a lot of good general knowledge, and then Merlin and Xeno Canto can help from there.
Highly recommend the Sound Escapes podcast by birdnote. It takes you to multiple locations where you can (among other sounds) listen to the bird calls.
I've found the combination of birdNET and Merlin out of the Cornell Ornithology lab to be pretty awesome for learning about the local birds on the fly. Pretty awesome work coming out of that group.
In the morning and early evening, there's a window where it seems like all the mockingbirds are singing from the various canopies, and it creates such delicate walls of sound. With the transitioning light, it's about as good as it gets. Once the blue jays start squawking, you know the chorus is nearing its end.
If you're interested in diving deeper into this bird world, I'd recommend starting with "What the Robin Knows" by Jon Young https://www.amazon.com/What-Robin-Knows-Secrets-Natural/dp/0...
Jon still does a lot of programs and workshops and research and it can be a fascinating rabbit hole to dive into.
