Here's why they do this:
* Easy food source: Finding dead animals is an efficient way for ravens to obtain food without the effort of hunting.
* Opportunistic eaters: Ravens are opportunistic feeders and will take advantage of any available food source, including carrion.
* Important ecological role: By consuming dead animals, ravens help to clean up the environment and prevent the spread of disease.
However, ravens also eat other things besides carrion:
* Insects: They'll catch and eat insects, particularly beetles.
* Fruits and berries: They're known to eat fruits and berries, especially during the summer months.
* Small mammals: Ravens are capable of hunting small mammals, like rodents and rabbits.
* Eggs: They will raid nests to eat eggs.
While ravens are primarily scavengers, they are also opportunistic predators and will take advantage of any available food source.
