Abstract
This was a field-based experiment to attempt to answer a question: Do birds have a favourite colour? Four coloured feeders (dark blue, green, yellow and red) and a clear control were used. The number of visits and the mass change in the feeders were recorded so preferences could be gauged. The results show a clear trend for blue being the preferred colour; red and yellow were unpopular.
We suggest that this is because high energy colours (blue and UV) are used by birds in short distance communication and that the blue feeder may have been the most detectable for the birds. We also suggest that red and yellow were unpopular because they are employed for aposematic colouration (toxins) in insects.

Applications of this research could include influencing the design of turbines or aeroplanes, to deter birds.
