Facultative Carnivore

Facultative Carnivore describes the concept of animals that are technically omnivores but who thrive off of all meat diets. Humans may just be facultative carnivores - who need no plant products for long-term nutrition.

Ingstad says that caribou are have parasitic insects growing in their throats which used to be a delicacy to the natives. They also eat the velvet on the budding antlers.

This is the season when the natives feast themselves on the newly sprouting horns of the deer. In velvet, they are but a few inches long and are covered with a pale green hairy skin. Lodged in the throat of each animal[caribou] is a handful of insect larvae. In olden times these constituted a great delicacy for the Indians, but today, as soon as the animal is slain, these grubs are dug out and thrown aside. Nor are the hides worth tanning at this season of the year. They are full of holes caused by bots or warbles.

The Land of Feast and Famine - Beaver Hunting

GreatWhiteOncomingSquare.jpg

While starving and looking for anything to hunt, the trappers come across a moose and spend 4 days drying out the meat before hiking back home. However, "moose meat makes one nat-seri (strong), as the Indians say, and when a man has a full belly, he has a different outlook upon life."

It appears as though, on the other side of a birch-clad hill, there might be another lake. Sure enough; I can already glimpse it shining through the trees and am just on the point of emerging from the woods when — the unbelievable takes place! A moose heaves in sight across the lake, runs out across a stretch of muskeg, and halts to sniff the air. What a mountain of edible flesh! 


At such long range I aim too low and succeed only in wounding the moose in one of its front legs. With that, it swings round and begins limping back toward the woods. It is just at this point that a fuzzy white shape darts from the woods and, before my very eyes, hurls itself upon the beast. I stare in utter amazement, until I suddenly recognize the familiar yelping of Trofast. Heavens, what a dog! He had probably thought to himself that we couldn't hope to do much hunting without him! So he had slipped his collar, a trick he can accomplish whenever he has a fit of hunting-fever, regardless of how tightly it fits. And here he is now, successful in running down his game and driving the moose straight in my direction. 


Many a time have I seen moose and dog come to blows, but never before a battle so desperately waged as this one. Trofast is everywhere. Like a wolf, he lunges in at his adversary, first from the front, then from the rear. Now he is crouching on his fore-paws right in front of the moose, barking and doing his best to tantalize it; he escapes the hoofs and antlers of the other by a mere fraction of a second. The moose sees red, feels the pain in its leg, and is out for murder. With head bent low and stiff staring eyes it stands waiting for an opening, then limps in the direction of the dog. Like a sledge-hammer whizzing through the air, that wounded leg flies out at the dog. Mud from the marsh splashes up where it lands. Round and round they go. 


I approach to within a short distance, neither of the combatants paying the slightest heed to me. At this point I deliver the coup de grace. At the very moment the moose topples over, Trofast pounces upon its rump with a snarl and begins wrestling to make it lie still. He is more eager than cautious, however, for the moose is still kicking, and it is not long before Trofast is sailing high and far through the air. He crawls to his feet again and returns, limping stiffly. This time, to be on the safe side, Trofast stations himself high up on the belly of the moose. Ah, there is a dog who can well feel proud of himself! 


Now I must make some effort to get hold of Dale. I set off in the direction of the river, shouting at the top of my lungs. All at once he breaks from the woods and comes running as fast as he can in my direction, his finger on the trigger. " What's up? " he calls from a distance. " Just shot a moose," I reply. " Oh, well," he says dryly. " I thought the bear had got you." 


The fact of the matter was that Dale had just been looking for some bear cubs he had heard squeaking up in a spruce-tree when he heard my wild shouts. There had been no doubt in his mind whatever but that the she-bear had got her dander up and was venting her spite upon me. . . . 


We remained at the place where I brought down the moose, for four days, simply gorging ourselves with meat. Meanwhile we fleshed and dried the moose hide and laid in a large store of dried meat. When we struck camp and set our course back in the direction of Slave Lake, both we and our dogs had tremendous burdens to carry. But moose meat makes one nat-seri (strong), as the Indians say, and when a man has a full belly, he has a different outlook upon life. . . .

The Land of Feast and Famine - Summer on Great Slave Lake

The trappers muse on the comings and goings of the mysterious caribou herds while also recounting periods of starvation in which they had to eat their own dogs.

There are many things which happen during the course of a year when one lives face to face with the wilderness and must rely entirely upon his dogs and his gun. The first matter of interest is the caribou, for they represent food. We have all encountered them, have seen the herds streaming out across the country, beneath a forest of antlers; we have all gorged ourselves on their flesh, haunted by the possibility of a day when the country would be empty of them, and the cold press in upon us and squeeze the life from our wretched bodies. We piece our recollections together and build for ourselves a picture of the caribou and its migrations, but we never succeed in discovering the first clue to the solution of the riddle of this mysterious animal.


Klondike Bill tells us about the time he was almost trampled underfoot by a herd of many thousand caribou. He had to crouch behind his sled, he said, whilst the herd, terrified by wolves, rushed by on every side. Joe had a hand-to-hand encounter with wolves up in the vicinity of the Coppermine River and escaped by the skin of his teeth. Bablet relates how once he was on the point of losing his dogs up on the Barrens — the very worst situation which could have confronted him. They were just making off with the sled in chase of a band of caribou, and Bablet had had no other choice but to shoot his train-leader. " The best dog that ever worked in the traces," he concludes. We others are not so willing to take his word on the latter point, however, for what trapper will ever admit that any but his own are the best dogs in the land? And woe be unto the man who, by innuendo or otherwise, dares to belittle them! Such is even worse than to mention to a man his wife's imperfections! A trapper may curse at his dogs and flog them unmercifully, but he always stands ready to do battle for them. 


Price has had a tough time of it during the latter part of the winter. He was on a long journey east when the caribou vanished completely. The dogs starved and one of them •— one of the most powerful beasts I have ever seen — began to get nasty. A primitive struggle for supremacy developed between dog and man. The dog was harnessed at the time, but it had become so wild and violent that it dragged the rest of the team with it when it decided to launch a lunging, snapping attack. At length, hopping up on the sled, it continued to give battle from there. Price conquered after a time, but it was a victory dearly won, and he would rather have fought with a grizzly bear, he says. Later, on that same journey, he became snow-blind, was taken so whilst he was off looking to one of his traps and had to feel his way back over his own tracks in the snow in order to find his dogs. "Wasn't much fun," he adds dryly. 


But, just the same, the one who had had the toughest time of all was certainly old Klondike Bill. Last autumn he had set off into the country with five big strapping dogs, and this spring he returned with but two. The other three he had eaten about Christmas time when he was starving on the shores of Kasba Lake. We all know of the affair, but it is a matter which no one ever mentions.

Now and then they offer me a bit of dried meat which a few of the more economical housewives have managed to save from the winter's hunt, but otherwise their diet is the same as mine: fish.

URL

After a day of toil I hop into the canoe and make my usual evening pilgrimage over to the river mouth to try my luck at trolling. There are plenty of trout to be had. They are continually pulling and jerking on the line, and in no time I have a boatful. With that, I call to the dogs and paddle homeward. The canoe glides gently forward over the silken water, whilst the light from the setting sun sparkles with a ruby phosphorescence in the ripples of our wake. . . . 


The Indians have settled with their families on the islands off Snowdrift. Occasionally I take a trip out to see them and am always received with the utmost hospitality. Now and then they offer me a bit of dried meat which a few of the more economical housewives have managed to save from the winter's hunt, but otherwise their diet is the same as mine: fish. 


The majority of the Indians are troubled with coughing. They catch cold every year with the coming of spring. The remarkably sound health they enjoy all winter long forsakes them as soon as warm weather sets in. Of those who are suffering with tuberculosis, it is invariably predicted that spring will see the last of them. But in so far as possible they pay very little attention to themselves. Cheerfully they enjoy the bright summer days, and when the hunters paddle off in their canoes, they sing so that their voices echo far out over the water. . . .

Chief Marlo, an old Indian in the Arctic: "My rich country. Caribou, musk-ox, fish, much food. Before, Indians all over. Great hunters. White man come, Indians die, all-a time die."

URL

Chief Marlo has not cut his hair like the others, for he is a member of the old school. Black and straight, it falls down over his shoulders. How old he is, not even he himself knows. " When I little, big battle, Dead Men's Island," he says. Now he is too feeble to join in the hunt. He remains indoors most of the time, smoking his pipe and giving advice. In a face of wrinkled parchment shine a pair of fun-loving eyes, and it may well be, as it is said, that he can still draw as fine a bead on a fleeing caribou as anyone. 


Each evening when the sun is setting over Great Slave Lake, Mario emerges from his tent and totters down to the beach. There he sits for a long time. On one occasion I sit down beside him. Not a word has passed between us when he nods toward the sun, just as it is slowly slipping down into the water in an orgy of red, and " Who you think make sun? " he asks. 


" Who do you think? " I parry. 


"Jesus — mebbe so," he says hesitantly. Just how sincerely he believes this to be true is pretty hard to know, for he immediately begins talking about how the sun, from the very first, has been the all-powerful god of the Indians. He flings out his arms to it and says: " First all water, then sun." 


But when Marlo begins to talk about his people, he is bitter and terse: "My rich country. Caribou, musk-ox, fish, much food. Before, Indians all over. Great hunters. White man come, Indians die, all-a time die." He points off toward the north where the woods melt like a bluish mist into the distance behind which lie the Barren Lands, and then he quietly adds: "When caribou come from Land without Trees, Indians choose new chief." 


I object by saying that he certainly has a number of years left to live. But Marlo shakes his head conclusively, as though he is positive of his statement. "When caribou come," he repeats, knocks the ashes from his pipe, and totters back up to his tepee.

Neanderthal diet at Vindija and Neanderthal predation: The evidence from stable isotopes

The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources

Archeological analysis of faunal remains and of lithic and bone tools has suggested that hunting of medium to large mammals was a major element of Neanderthal subsistence. Plant foods are almost invisible in the archeological record, and it is impossible to estimate accurately their dietary importance. However, stable isotope (􏰃13C and 􏰃15N) analysis of mammal bone collagen provides a direct measure of diet and has been applied to two Neanderthals and various faunal species from Vindija Cave, Croatia. The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources. Earlier Neanderthals in France and Belgium have yielded similar results, and a pattern of European Neander- thal adaptation as carnivores is emerging. These data reinforce current taphonomic assessments of associated faunal elements and make it unlikely that the Neanderthals were acquiring animal protein principally through scavenging. Instead, these findings portray them as effective predators.


Stable Isotope Analyses.

Mammal bone collagen δ13C and δ15N values reflect the δ13C and δ15N values of dietary protein (14). They furnish a long-term record of diet, giving the average δ13C and δ15N values of all of the protein consumed over the last years of the measured individual's life. δ13C values can be used to discriminate between terrestrial and marine dietary protein in humans and other mammals (15, 16). In addition, because of the canopy effect, species that live in forest environments can have δ13C values that are more negative than species that live in open environments (17). δ15N values are, on average, 2–4‰ higher than the average δ15N value of the protein consumed (18). Therefore, δ15N values can be used to determine the trophic level of the protein consumed. By measuring the δ13C and δ15N values of various fauna in a paleo-ecosystem, it is possible to reconstruct the trophic level relationships within that ecosystem. Therefore, by comparing the δ13C and δ15N values of omnivores such as hominids with the values of herbivores and carnivores from the same ecosystem, it is possible to determine whether those omnivores were obtaining dietary protein from plant or animal sources.

FOCUS: Gough’s Cave and Sun Hole Cave Human Stable Isotope Values Indicate a High Animal Protein Diet in the British Upper Palaeolithic

We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus

We undertook stable isotope analysis of Upper Palaeolithic humans and fauna from the sites of Gough's Cave and Sun Hole Cave, Somerset, U.K., for palaeodietary reconstruction. We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus. There are a large number ofEquus sp. faunal remains from this site, but this species was not a significant food resource in the diets of these Upper Palaeolithic humans.


If the humans hunted and consumed mainly horse, then their 15N values should be c. 3–5‰ (Equus 15N value of 0·7‰+enrichment of 2–4‰). Instead, their 15N values make more sense if they lived mostly off Bos and Cervus elaphus (Bos and Cervus values of c. 3‰+enrichment of 2–4‰=the observed values c. 6–7‰). It is also possible that other species, including Rangifer tarandus, were consumed by these individuals. Rangifer tarandus has 15N values similar to Cervus elaphus (Richards, 1998), and has more positive 13C values, which may explain the observed slight enrichment in the human 13C values. A number of artefacts made from Rangifer tarandus have been found at Gough’s, but there is no other evidence that this species was being exploited for food
