        This is suggesting that we should be using hive covers. What exactly changed in the mid 20th century?

          We stopped using hive covers because they’re more expensive than the increased mortality. They naturally nest in tree hollows in winter, whose thicker walls (and living material) allow the hive to maintain a higher internal temperature than uncovered hives (or covered hives).
