The colour flowers influence to visiting of animal pollinators by adaptation in the evolution to be able to live together makes the flowers with multiple colors. There is previous research found that plants have the reflection spectrum make pollinators can see the color of the flowers. These studies did not test with birds. There are compared with insect and avian vision by sampled Australian angiosperm species for color measurement using reflectance spectra from wavelengths to the analysis spectral signals. Use the reflection spectrum of wavelengths of flowers and analysis of metrics calculated by MAD minAD and phylogenetic ANOVA to compare the visual system of insects and birds. Study results showed that the reflection of the light spectrum of flowers match the visibility of the insects and birds. In particular, bird-pollinated flowers to reflect radiation waves near 600 nm. To make a difference with the color of the leaves and birds can remember easily. There is also research that supports the vision of birds found that the color of cut flowers with green leaves to attract birds by the above vision of insects to reduce competition from the flowers of the same species. Therefore, bird-pollinated flowers will be red to differentiate other types of flowers.
