Which bird is most tolerant of cold weather conditions?

The Red-tailed Hawk is recognized for its remarkable adaptability to a range of weather conditions, including cold climates. This species has evolved to thrive in various environments across North America, from deserts to forests and even urban settings. Its ability to tolerate cold weather is partly due to its substantial body size, which allows for heat retention, and its dense plumage, which provides insulation against frigid temperatures.

In contrast, the other birds listed, such as Harris' Hawk and Aplomado Falcon, either prefer warmer climates or have less adaptation to extreme cold conditions. Harris' Hawks are known for their social behavior and typically inhabit more temperate regions, while Aplomado Falcons primarily dwell in warmer areas and are less equipped to handle harsh winters. Therefore, the Red-tailed Hawk stands out as the bird best suited for enduring cold weather, making it the most suitable answer.
