What a weird coincidence. I currently live in the city, where there is a stark absence of birds -- besides maybe coronavirus pigeons and gulls that will mug you down a dark alley -- but I'm from and work in the countryside, where I've established an acute awareness of the local bird life. I particularly like listening to bird song; I find it very relaxing. As recently as last week, I was thinking about compiling an Anki deck to help me learn to identify birds by sight and by their song. However, I was discouraged not so much by the quantity, but the subtleties in the differences (e.g., the aforementioned pigeons vs. wood pigeons: one has black stripes on their wing tips, but I don't remember which)... Seeing this, this morning on HN, re-encourages me to pursue ornithology as a hobby :)
