Hawks, like other birds of prey, do not require direct exposure to the sun for survival. However, they do benefit from spending time in sunlight for various reasons. Sunlight helps in thermoregulation, as hawks warm themselves by absorbing solar radiation. It also aids in maintaining feather health by promoting the production of vitamin D, which is crucial for proper feather growth and maintenance. Additionally, sunlight provides opportunities for hawks to spot their prey more easily, improving their hunting efficiency. However, too much sun exposure can be harmful, leading to overheating or sunburn. Therefore, hawks strike a balance between basking in the sun and seeking shade to regulate their body temperature and protect themselves from excessive UV radiation.
