采用选择性漂白和早期感受器电位（ERP）记录两种独立的方法，对鸡和鸽离体视网膜的视色素进行了测定。漂白动力学和ERP光谱灵敏度曲线均显示存在至少4种在413、467、507和562 nm附近具有最大吸收的视色素。证明P467和P413是真实的视色素，而不是视紫红质或视碘质衰变过程中形成的光产物。视紫红质-507的一部分可能被封闭在锥细胞内。鸡和鸽子的眼部介质在340 nm以下是透明的，并且不会干扰紫色敏感色素的功能。鸟类的色觉和其他脊椎动物一样，利用了多色素锥系统。
Visual pigments in the chicken and pigeon isolated retina were determined with 2 independent methods using selective bleaching and recording of the early receptor potential (ERP). Both the bleaching kinetics and ERP spectral sensitivity curves showed the presence of at least 4 visual pigments having absorption maxima near 413, 467, 507 and 562 nm. Evidence was presented that P467 and P413 were real visual pigments and not the photoproducts formed during the decay of rhodopsin or iodopsin. Some fraction of rhodopsin-507 was probably enclosed within the cones. The ocular media in chicken and pigeon were transparent down to 340 nm and did not disturb the function of the violet-sensitive pigment. Color vision in birds, as in other vertebrates, exploits the multi-pigment cone system.
