Helpers in the Nest - Taiwan Yuhiha

Although Taiwan Yuhina is easy to observe in the hill forest in Taiwan, not many people know they are joint nesters. Joint nesting is a rare form of cooperative breeding. This poster aims to introduce Taiwan Yuhina and its life stages to park visitors and explains the joint-nesting system. The scene depicts two Taiwan Yuhina couples taking care of nestlings together. The environment of the scene shows that Taiwan Yuhina’s nest is usually located along forest edges. The morphology of the egg is painted based on text documents because of a lack of photographic resources. I used a color blindness simulator to ensure the poster is accessible to individuals with color vision deficiency.
