Abstract: | Professor Rudolph Drost was the first to devote full attention to this theme. in the numerous male Pied Flycatchers Ficedula hypoleuca on sprinq migration on Heliqoland the upper-parts showed considerable variation in colour. While in some males the upper-part was black throughout, others lacked black almost completely. Drost examined 237 skins from North and Central Europe, and worked out 7 colour-categories for classification. At the same time he was aware of the fact that more or different categories might be chosen. However, in the meantime these 7 categories have been generally accepted and proved to be practical. |
