OR WHERE THERE ARE FEW DEER,LIKE WMU2G

douge, ERIC GESE state biolgist on coyotes at yellowstone park said,HE FOUND DEER CALF BONES IN 3 COYOTE DENS

bowtruck

nat geo channel had show Yellowstone showing how they had all coyotes ,foxes, predators
taken out the population exploded of all the other wildlife they had over 2000 bisen starve to death
elk and deer all in one winter good show my enlighten some ppl

sproulman

yes, did you see where he said that 3 dens had deer calfs in dens.

hey douge,yooooooooooo,douge

When the female gives birth the male does hunt for her. So yes they will take animal parts back to the den for the pups. And the timing of this is around the time does give birth. Also about the bear and coyote, I would have to say now that we have 5 times as many yotes as we do bears.So coyotes would now do more damage to the fawn population than bear does.

Studies in Texas have shown that the coyote’s diet consists of 70% fawns during June and July.


Predator-prey relationships between the white-tailed deer and the coyote have been extensively studied. The coyote is a significant predator of deer fawns. Studies in Texas have shown that the coyote’s diet consists of 70% fawns during June and July. Sheep predation by coyotes is known to drop drastically when fawns are born around the first of June. The synchronous birth of fawns in June allows the numbers of fawns to overwhelm the predators, and although a large number of fawns are taken during the first month of the fawns’ lives, they become relatively secure after about one month. During winter predation again picks up and deer again become the main diet of coyotes. Although the coyote takes healthy adult deer during the winter, winter killed and wounded deer as well as carcasses and offal from hunting season probably make up the bulk of the winter diet.


In Maine, food habitat studies showed that white-tailed deer made up 50-60% of the coyote’s diet, and this predation had the potential to have significant negative effects on the deer herd. Coyote predation in the high mountain areas of West Virginia with lower deer populations and severe winters is likely to have more effect on the deer herd than in areas with higher deer populations.

Sproul,read the fawn study journal.Out of all the fawns that were collared,none neded up ina coyote den.They don't do that.

Here's a quote from Wisconsin's DNR.Oneway you can tell a fox den from a coyotes den is by the tidiness inside and around the entrance.Unlike foxes,adult coyotes remove bones and other debris so tyhese materials don't accumulate in or around the edges of the den.

In a fawn survival study in Centre County Pennsylvania during 2000-2001, 218 fawns were radioed and followed with telemetry equipment. Of these fawns, predators killed 22 percent, the leading source of mortality. Of the fawns killed by predators, most were killed by coyotes (49%) and bears (43%). Nearly 50% of all mortality occurred during the month of June, with 18 percent and 16 percent in July and August. It was interesting to note that 84 percent of fawn predation occurred on one of two study areas. This probably illustrates the difference in predation rates due to localized coyote populations.

So with your HR,I would think that 50% of fawns are killed by predators.

Coyotes can and occasionally will prey on a fox though it appears to be an extremely rare occurrence. The real reason fox numbers, both red and gray, tend to decline when the coyote numbers increase is simply because they use the same prey base and since the coyote is a larger and more skilled predator he out competes the fox for both the prey base and the no prey food supply. Then since nature guarantees that no population can exceed its food supply for more then short term periods or ideal conditions the fox populations naturally decline. That has nothing to do with predation and is strictly a result of completion for the available food supply.

Coyotes do NOT out compete the bobcat. In this part of the state we had lots of coyotes and few bobcats ten to twenty years ago. Now we have continuously increasing bobcat numbers and it seems that the coyote numbers have declined with the increasing bobcat populations. The bobcat is a very equal predator to the coyote even though they do share some of the same prey base. Coyotes are not going to tangle with or try to prey on a bobcat unless it is a very young unprotected one.

Adult to adult I suspect the bobcat would win out in a fight with a coyote, but those battles are extremely rare in wild populations since predators almost never want to enter into any fight where there is even a remote chance of being injured. They instinctively know that an injury, even a minor one, likely means death. They aren’t going to put their life at risk unless things are in a very desperate state toward their own survival.

As for the nose on a coyote or any other predator it simply doesn’t matter when it comes to fawns. The fawns have no scent distinguishable to a predator for the early stages of their life. That is why after they have nursed they walk off and lay down to hide while the doe walks off in a different direction. The predators can track the does, by scent, and they do sometimes do that hoping to get into the right area to stumble onto a fawn. If they do they kill it but it was simply because the fawn failed to remain hidden or the predator got lucky and just stumbled upon the fawn. By the time fawns are leaving scent they can generally outrun a predator.

Noonan said a good example of how coyote control can benefit deer is what happened on the Gaspe Peninsula in Quebec, just north of the Maine border. In 1986, had a healthy herd of about 15,000 whitetails, and a low coyote population.

However, after several consecutive harsh winters — and extensive clear-cutting that eliminated traditional yarding areas — coyotes got the upper hand and wreaked havoc on the deer population.

By 1991, researchers estimated that only 500 deer remained on the peninsula. To save the herd, the province banned deer hunting, implemented strict logging regulations and implemented an aggressive coyote snaring program.

According to Noonan, 80 trappers were trained to snare coyotes, and they were instructed to focus their efforts on 80 percent of the remaining deer yards.

The plan worked. In just three years, the trappers caught 1,500 coyotes. Deer numbers rebounded, and by 1999, the peninsula had a population of more than 2,000 whitetails.

However, the coyote problem didn’t end there. When the snaring program was stopped for two years, the coyote population rebounded, and the deer population again decreased.

As a result, the peninsula instituted a subsidized trapping program that is still used today.

I read that study and it's a differen tsituation.Those deer are yarded up and they're sitting ducks.

In Quehanna 69% of the fawn mortality was from predators.That's noteven close to 50% being killed by predators.
