Attack of the Flesh Eating Vegetarians!


A grey squirrel snacks on a bird.

This morning I tackled the question of why dogs eat grass.

Now, let's look at the inverse.

Do elephants and hippos ever eat the flesh of large animals?

Do squirrels and chipmunks ever eat eggs and insects?

And the answer is "YES."

No, this does not happen every day, but it happens often enough that it is well known and well within the arc of "normal," if not typical, of the species.

Why?

Why do "vegetarians" sometimes eat flesh?

The answer, as with dogs, is that it is maladaptive for them not to do so.

A squirrel, chipmunk, hippo, elephant, or deer may occasionally get a massive calorie, iron, salt or calcium boost by eating all or part of a dead wildebeest, zebra, eland, or baby bird.

The divisions between "carnivore" and "vegetarian," then, are not quite as neat as some would have us believe.

Horses and cows have been known to nibbel on free range chicks. There is a video on youtube for the disbelievers.

One winter I hung the skin of my year's deer on the back fence, intending to scrape it and send it to be tanned the next day.

We had an early, persistent, and astonishingly hard freeze for December. A week later I found the skin mostly eaten -- just a pile of deer hair. It was surrounded by nothing but rabbit tracks.

I emphasize in my programs how most animals are crossovers with their diet. Even my hawks will occasionally eat the vegetation in stomach contents of their prey. My macaw loves bone marrow, and meat (even chicken).

This time of year in Northern Arizona, the coyote scat is almost entirely juniper seed. Later in the summer they will go through grass, grasshoppers, rodents and rabbits, and deer, but right now they seem to be living on mostly juniper berries.
