How does the *Naja nivea* behavior shift in the scorching Karoo summer heat?

Becoming primarily nocturnal or crepuscular

As an ectotherm, the activity levels and foraging times of the Yellow Cobra are intrinsically linked to the ambient temperature, which is a critical factor in its desert-edge environments like the Karoo. During the intense heat experienced throughout the Karoo summer, the snake must adjust its schedule to avoid potentially lethal daytime temperatures. To manage this thermal stress, these cobras frequently shift their activity patterns, becoming primarily nocturnal (active at night) or crepuscular (active during dawn and dusk). This shift in foraging time often strategically aligns with the activity periods of their primary prey, such as rodents, maximizing hunting success during cooler, safer hours.
