Extended exposure to direct sun in high temperatures can indeed be fatal to any species, including raptors. Raptors, like all birds, are susceptible to overheating and dehydration when exposed to extreme heat for prolonged periods. High temperatures can lead to heat stress and heatstroke, particularly if the bird does not have access to shade or water.

In nature, raptors have adapted behaviors to help them cope with temperature extremes, such as seeking shade or being active primarily during cooler parts of the day. However, intense heat can overwhelm these adaptations and lead to serious health issues, making it vital for falconers and those who care for raptors to ensure that their birds have proper shade, hydration, and temperature regulation, especially during hot weather.

The other options underestimate the impact of heat stress on raptors and do not take into account the physiological needs that all birds share in extreme weather conditions.
