So for bears, the best strategy is to prey on the young of a species, then to only attack the adults when they are at their weakest, or to feed on the carcasses of medium and large animals whenever possible.Ī targeted study conducted between 20 in the Abruzzo, Lazio and Molise National Park shows that six bears consumed a total of at least 52 carcasses during the summer and autumn, corresponding to one carcass every 8-28 days for the females and one every 3-9 days for the males. Bears have specialised in usurping carcasses killed by other predators such as wolves and lynxes, a phenomenon known as kleptoparasitism. The larger the carcass, the more likely it is to attract other competitors, but the smaller it is, the less likely it is to be found before being eaten by other scavengers. But even eating only carcasses is not such an obvious choice, because you can only benefit if you’re the only one eating them. The general rule is to avoid large, aggressive animals that could put the predator’s own life at risk. The more a prey is vulnerable, available (present in large numbers) and accessible (non-aggressive and easy to isolate), the more likely it is to be chosen for an attack. It’s the opportunity that makes the bear a predator. Its smaller size and physiological and morphological adaptations for a strictly vegetarian diet make the Marsican bear one of the brown bears most able to gain weight by feeding mainly on plants.īrown bears are basically necrophages (in other words, they eat animals that are already dead), but they can also prey on red and roe deer, elk and even bison, albeit with less agility than wolves. But the harsh, snowy winters debilitate the elk, making them an easy meal in the first few months after the snow melts. The trees in those forests do not produce nutritious energy-rich seeds, such as pine nuts, beechnuts, acorns or chestnuts. The hibernation period can last over six months and bears lose much more weight than do their southern counterparts. In northern latitudes, bears have very short summers and very long winters and they have very little time indeed to fatten up by eating mainly fruits and herbaceous plants. Actually though, it’s not so surprising if you consider three factors: temperature, snow conditions and the availability of food. This may seem a paradox when you think, for example, that only one or two species of wild ungulate live in the boreal forests, whereas there may be as many as seven in southern Europe. So this is what the doe wanted to protect: her newborn infant. When it reaches its target, the bear plunges its head down into the grass, then walks away into the woods, clutching in its jaws the inert corpse of a fawn just a few weeks old. The bear ignores the doe and goes back to sniffing determinedly in the direction the doe sprung out from. Drawing attention to herself would seem suicidal or desperate. Then surprisingly, she starts jumping about in all directions in front of the predator. After about twenty minutes, when the bear is just a few dozen metres away, the doe leaps sideways, but does not flee. The distance between the doe and the bear gets shorter and shorter. It zigzags with its nose to the ground, sniffs the air, then retraces its steps again and again. It starts moving again like a bloodhound in search of its prey. As soon as the wind veers in its favour, the bear stops, sniffs the air and rises up a little on its hind legs. Hidden in the tall grass no more than 150 metres from the bear, an alert doe concentrates on the potential predator. A bear is quietly grazing downwind, browsing on leaves and shoots. Sharks are predators, yet dolphins and whales hunt on them.At dusk, bears make their appearance in the clearings at the bottom of the valley in search of fresh vegetation, but that’s not all. A predator is not always the top of the food chain, as other species might prey on them. It has keen teeth and claws to kill its victim, yet it has strong legs to outrun it.Īn apex predator is at the top of the food chain, meaning no other species preys on them. The difference between a predator hence isn’t whether they hunt other animals, but whether they’re hunted themselves.Ī predator is an animal that hunts and kills other creatures for sustenance. Predators prey on other animals but are also preyed upon. Difference Between Predator and Apex PredatorĪn apex predator isn’t preyed upon by other animals. When top predators are removed from the equation, prey populations can quickly spiral out of control, which can disrupt the balance of the entire ecosystem. Hunting mode (ambush or active hunting)Īpex predators play a vital role in the ecosystem by keeping prey populations in check.Predators typically have the following four traits : ![]()
