Knowledge graph centered on Tetrachromatic color vision modeling (Trochilidae) with 19 nodes and 38 connections. Top connected: Wild hummingbirds discriminate nonspectral colors, Synchronization of speed, sound and iridescent col, courtship displays, chromatic contrast, pavo visual modeling framework.

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
