摘要

The Colortron (Light Source, San Rafael, california) is an inexpensive, compact, Macintosh-compatible reflectance spectrophotometer than can be used to quantify the col- Oration of the plumage and soft parts of birds. The Colortron provides a reflectance spectrum (390-700 nm) of the object being measured as well as tristimulus color scores that can be compared to scores from the Methuen or Munsell color references. Because the Colortron fails to measure ultraviolet light (wavelength <390 nm), which is visible to some species of birds, Colortron output must be interpreted cautiously when is used to describe plumage that may reflect UV, especially if the focus of the study is understanding the function of coloration.
