Résumé :	I propose a methodology to obtain and compare integral information on bird plumage coloration, using colour spectral data to conduct studies on geographic variation and taxonomy of different bird groups. I used principal component analysis and discriminant function analysis to compare groups of individuals by plumage coloration. As examples of the application of the methodology, I compared populations within the genus Eulampis and Anthracothorax. The results indicate possible taxonomic inadequacies and reveal situations that deserve further analysis, demonstrating the potential of the methodology in this area.
