Many diurnal birds possess a set of four spectrally different types of cone photoreceptor. The spectral range of vision is extended into the UV by a UV receptor. We have investigated the spectral properties of plumage colours including the UV by reflection spectroscopy. Some basic general principles of colour vision indicate that plumage colours are tuned to avian colour vision.
许多昼行性鸟类拥有一组四种光谱不同类型的视锥光感受器。紫外线感受器将视觉的光谱范围扩展到紫外线区域。我们通过反射光谱法研究了包括紫外线在内的羽毛颜色的光谱特性。一些基本的颜色视觉通用原则表明，羽毛颜色是根据鸟类的颜色视觉进行调整的。
