When does the Stoat turn white in winter?

In summertime the fur of the stoat is sandy-brown on the back and head and a white below and turns completely white in winter with the tip of the tail remaining black. Analysis of fortuitous observations show that stoats start molting in October. Molting individuals are observed every month from October to April with changing frequency. Stoats in brown summer fur seem to be absent only in January and February. The first individuals completely white appear during November and the last are observed in April.  As the molt is initiated by the length of the day and the temperature, climate change could in future take influence on this process. Information about the molt are consequently of importance. We ask therefore all observers of stoats to mention if the animal wears a completely brown summer fur or white winter fur or on the other hand has not yet completely molted.
