In Australia, honeyeaters are far and away the most abundant and important nectar-feeding birds, so also the most important avian pollinators of flowers.
What effect has their visual perception had on the evolution of colour among the flowers they visit?
Today, a team of biologists from Monash (including me) and RMIT universities in Melbourne and Bucknell University in the US published the most quantitative and rigorous investigation of this question to date.
We used mathematical models of bird vision to represent the colours of Australian flowers as birds are likely to see them.
