  I have just started reading *Winter World* by Bernd Heinrich. In his chapter
  on snow and subnivian space he claims that Grouse and other birds actually
  burrow under the snow: -- " in the Maine woods I routinely find over thirty
  fecal pellets (in these snow shelters) where a ruffed grouse has spent the
  night. Often these birds also stay the day in their shelter, because on
  snowy, cold days I have flushed them out from underfoot under the snow even
  at noon."

  I have seen snow accumulate on birds, but I had never heard of them
  burrowing in it.

  Your thoughts or observations?
