Here's why:
* Lower competition: At these times, other predators are less active, giving cougars a better chance at catching prey.
* Temperature: Dawn and dusk offer cooler temperatures, which are ideal for hunting. Cougars are very efficient at hunting but can overheat easily.
* Prey activity: Many prey species, like deer, are most active at dawn and dusk, making them easier targets for cougars.
However, cougars are opportunistic hunters and will hunt at other times of the day if necessary. They can be active throughout the day, especially if they are hungry or if prey is scarce.
