Why does a predator not sense a hare in its burrow, despite the heat it emits? 0 33

First of all, it should be noted that digging burrows and living in them is characteristic not of hares, but of their close relatives — rabbits. Hares, except for the white hares from tundra populations, do not dig burrows, aside from temporary shelters for sleeping under the snow.

The animal hiding in the burrow does indeed emit heat, but it is almost completely dissipated into the soil. Moreover, predatory mammals, which are natural enemies of hares and rabbits, do not possess organs capable of detecting thermal radiation. The predator picks up the scent coming from the inhabited burrow.

Upon discovering the entrance to the burrow, wolves or foxes attempt to dig it out, but this rarely leads to success: rabbit burrows are long, deep, and may have several exits.
