Which of the following is a common sign of a healthy bee colony?

A common sign of a healthy bee colony is active foraging. When bees are actively foraging, it indicates that the colony is thriving and has a sufficient population to venture out and search for nectar, pollen, and other resources. This activity is essential for the colony's survival and productivity, as foraging provides the necessary food and sustenance for the bees and their brood.

In a healthy colony, active foraging is often accompanied by a robust and well-organized hive, demonstrating that the bees are efficiently carrying out their roles and that the colony is effectively meeting its needs. This foraging behavior also reflects a stable environment and availability of floral resources, contributing to the hive's overall vitality.

In contrast, low hive activity suggests potential issues within the colony, such as a dwindling bee population or inadequate resources. Random brood patterns can indicate problems with the queen or brood disease, while the presence of disease symptoms is a clear sign of distress in the colony. Each of those factors can hinder the colony's health and productivity, making active foraging a vital indicator of a thriving bee ecosystem.
