For birds, red means 'go'
Date:3/5/2013

d how colour may continue to evolve in particular environments depending upon the availability of effective pollinators.

"The colour cues in Australian flowers would be easily detected by honeyeaters, the most important family of nectar feeding birds in Australia. Hummingbirds in the Americas have similar visual systems to honeyeaters, so we expect to find similar colour signals among American flowers," Associate Professor Burd said.

"But in Asia and Africa, birds with a different type of colour vision are the primary avian pollinators. If flower colours in these regions are tuned to the specific capacities of their own birds, we would have strong evidence that we've cracked the code that plants use to communicate with birds."
