About the event

The talk will first look at what colours birds can see and how that affects their lives, after which it will move on to how feathers are coloured. This will the lead into a discussion to prove, or otherwise, Charles Darwin’s hypothesis that animals and birds in particular are more colourful the closer one gets to the equator. The talk will be illustrated with photographs taken from John’s many visits to tropical countries with particular emphasis given to those taken in Brazil’s Atlantic Rainforest.
