Why should outdoor enclosures provide sun exposure on cool days?

• A. To attract insects
• B. To help birds see better
• C. To allow basking and thermoregulation
• D. To deter predators

Answer: (C)

Sun exposure on cool days supports thermoregulation through basking. Even in birds, warming up in the sun helps raise body temperature to a level that enables key bodily processes like digestion, metabolism, and healing. When the enclosure offers sunny spots, birds can voluntarily bask to reach that optimum temperature, which improves energy, coordination, and recovery after injury or illness. Without access to warmth, they can become slow, stressed, or hypothermic, delaying healing. Balance sun with shaded areas and water so they can regulate temperature safely across varying conditions.
