[Taxacom] Gloger's rule

[Philippe Golay]

Dear all,

looking at various definitions of Gloger?s rule, I?ve noticed that heat and
humidity are always cited.
However, it seems that in the chapter concerning colour?s changes from his
1833 book ? Das Abaendern der V?gel durch Einfluss des Klima?s ? (pp.
11-23), no sentence refers specifically to humidity.

Do you have any 

Thank you for your help!

Philippe
