Résumé :	This practically oriented introduction deals with potentialities and limitations of the use of multivariate statistics in field ornithology. Principal Component Analysis, Discriminant Analysis and Cluster Analysis belong to the most important multivariate statistical techniques in ecological research. This paper introduces the theoretical basics and also offers guidance on the application of these techniques. Furthermore, indicators of the quality of analysis and possibilities of interpretation are discussed for each technique and demonstrated on the basis of an empirical example.
