If a red-tailed hawk encounters a snake, it may hunt it depending on the size and the hawk's hunger level. Red-tailed hawks are skilled hunters and use their sharp eyesight and talons to capture their prey. If successful, they may consume the snake, starting with the head and then consuming the rest of the body.
However, it's worth noting that individual red-tailed hawks can vary in their preferences, and some may hunt snakes more frequently than others. Additionally, factors such as the habitat, season, and prey availability can influence the hawk's dietary choices.
