What does "A Once in a Lifetime Bird" tell you that isn't "a long-form article about birdwatching or ornithology or something"? It's not particularly calling you to any specific action. Clicking through and seeing the subtitle "Birding saved one man’s life. Maybe it can save the rest of us from climate change?" makes it even more obvious that it's some sort of personal story. I read that headline and my first thought is "I don't particularly care about birds, probably not gonna click." (My second thought in this case was "curious to see on HN, I wonder if there's a specific connection?" so I clicked the comments.)
