e/Overwintering

Information
has gloss	eng: To overwinter is to pass through or wait out the winter season, or to pass through that period of the year when “winter” conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases “winter” is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Alternately, overwintering can refer to spending winter in a more favourable (usually warmer) locale.
