Description
Novel method using programmable LED devices to test color discrimination in free-flying hummingbirds through reward-based choice experiments. Birds choose between tubes displaying different colors in avian tetrachromatic color space, with sucrose rewards for correct choices.
Typical Equipment
- TetraColorTubes
- tripod platforms
- sucrose solution
- Ocean Optics USB4000 spectrometer
Output Measurements
- color discrimination probability
- choice frequency
- learning curves
