Bees winter food
Honey bee colonies evolved to survive during winter when there is little to eat outside. The honey bee population reduces from 50,000 in summer to 10,000 worker bees and one queen. They huddle together and shiver their flight muscles to keep themselves and their home warm. They get the energy to shiver from eating their stores of honey which they have built up over the spring and summer by turning nectar collected from the flowers into honey.
