A striking Xiaohongshu cover page, 1080x1440px, strict 3:4 vertical portrait. Outdoor travel geographic annotation style (户外旅行地理标注风), urban birdwatching theme. Earth tone palette: sand beige, ochre, olive green, deep brown, with off-white annotation labels. The central visual: a spotted dove (珠颈斑鸠) with its distinctive pearl-like neck collar, photographed naturally sitting on a park bench or tree branch in an urban park — morning soft light, slightly misty, peaceful. Around the bird, 3-4 thin ochre (#b86b4a) annotation lines with small map-pin icons pointing to the bird characteristics: neck collar, wing pattern, tail. A subtle dashed route line curves through the background suggesting a walking path through the park. At the top, large Chinese headline area: "家门口的公园，我数到了12种鸟" in bold sans-serif. The mood: quiet discovery, nature hiding in plain sight, like Cereal travel magazine meets urban nature field guide. No people. No neon colors. No blue-purple gradient. No plastic fake look. Authentic and warm.
