# 渡渡鸟贴纸来源记录

- 文件：`raphus-cucullatus.png`
- 更新日期：2026-11-01（Asia/Shanghai）
- 制作：BirdGacha / OpenAI ImageGen，使用内置 image_gen 工具，透明背景。
- 用途：替换旧通用鸟形 SVG；独立生成的渡渡鸟插画，不是 huashu-bird-sticker 仓库中的原始贴纸。
- 生成图不是照片或科学复原的精确记录。

1. [huashu-bird-sticker](https://github.com/alchaincyf/huashu-bird-sticker)：已核查 main 分支 README、species.csv 和完整文件树。该库只包含现存鸟类，明确不含灭绝种，因此没有渡渡鸟贴纸。

此图是 AI 生成素材，不沿用旧占位 SVG 的 CC0 标签，也不标成花叔原仓库贴纸。参考素材各自的授权不因重新生成而改变。

## 最终生成提示词

```text
Use case: scientific-educational.
Asset type: production-ready transparent bird sticker for BirdGacha collectible cards.
Primary request: create ONE original detailed hand-painted digital illustration of a dodo, Raphus cucullatus, matching the softly rendered natural-history illustration style of the provided pigeon sticker.
Input images: image 1 (museum dodo reconstruction) is general anatomical guidance ONLY; do not reproduce the photograph, specimen, exact pose, lighting, background or texture. Image 2 (pigeon sticker) is style and finish reference ONLY; do not use pigeon anatomy.
Subject: a full-body adult dodo standing calmly in a fresh natural three-quarter profile facing right. Highly recognizable long massive ivory-grey bill with swollen dark charcoal downward-hooked tip, small alert amber eye, bare grey face, sturdy slightly curved neck, full pear-shaped slate-grey and warm taupe feathered body, very small vestigial wings held against body, small cream-white curled tail plume tuft, two thick ochre scaly legs with three forward toes and one rear toe, dark curved claws. No long flight feathers or long pigeon tail.
Style: polished semi-realistic natural-history bird illustration, fine layered feather detail and gentle painted shading, clear readable silhouette at 200px, similar visual detail to the existing bird library. Calm dignified expression. Muted natural colors suitable for a dark platinum-purple legendary card.
Composition: single isolated bird centered, full beak, curled tail, both feet and every toe visible, modest 5-7% transparent padding, roughly square artwork, bird fills the frame.
Background: genuine alpha transparency. Add a neat narrow consistent white die-cut sticker outline around the entire bird silhouette. No scenery, no ground plane, no cast shadow, no colored backing.
Constraints: image only, no text, no badge, no card UI, no frame, no watermark, no fake checkerboard. Must read immediately as a dodo, not a pigeon, duck or turkey.
