As the outside air temperature decreases the winter cluster becomes tighter and more compact.

They do not form such tight winter clusters.

The temperature within the winter cluster remains remarkably warm regardless of the outside air temperature.

The bees will lose access to this during the winter cluster in the hanging combs, thus increasing their likelihood of starving.

The winter cluster within the hive must move throughout the winter to reach the available honey stored in the combs.

Lamarckii does not form winter clusters and therefore the pure strain cannot overwinter in areas that experience freezing temperatures.

Mr. Whynott writes finely, often lyrically, of the mating flight, the winter cluster, the swarm.

Queen excluders are removed in the autumn; otherwise, the queen would not be able to move with the winter cluster and would die from exposure.

In temperate and equatorial regions, a winter cluster will survive in a single box or in a "nuc" (short for nucleus colony).

Dr. Orton's breeding efforts with non-evergreen hollies, which feature winter clusters of red or orange berries on bare branches, has led to outstanding shrubs.

In the late winter and early spring as the brood cycle begins, the queen starts to lay eggs within the winter cluster in proximity to available honey stores.

These adaptations include brood cycles synchronized with the bloom period of local flora, forming a winter cluster in colder climates, migratory swarming in Africa, enhanced foraging behavior in desert areas, and numerous other inherited traits.

On a warm noon when sun strikes the hive, the bees still fly, but it has been cold enough recently for them to form their winter cluster, a tight, buzzing ball at the center of their store of brood and honey.
