Gloger was the first person to recognise the structural differences between

He was the originator of what is now known as Gloger's rule, which states that dark pigments increase in races of animals (birds were the examples in which he originally noticed the pattern) living in warm and humid habitats. He put forward this theory in his Das Abändern der Vögel durch Einfluss des Klimas (1833). The exact way this pattern is actually caused is still unclear, but in birds it has been suggested that darker pigmented plumage provides protection against feather-degrading bacteria, whose activity is greater in warm and humid regions.^[1] His other works include Gemeinnütziges Hand- und Hilfsbuch der Naturgeschichte (1841).
