Even with Eastern Coyotes having 10-25% Eastern Wolf genes, a lone Coyote is unlikely to kill a Whitetail Deer if the deer stands its ground and does not flee...........There is no question that Eastern Coyotes enjoy a venison meal and are key predators of newborn deer fawns in the Spring,,,,,,,,,,,In the first couple of weeks after birth, before being able to "run like the wind", Bears and Coyotes opportunistically kill fawns they come across as they patrol their territory.............In the video below, a good size Maine Eastern Coyote(25-55 pounds as a rule versus 20-35 pound Western Coyotes) comes up empty handed in a "cage match" with a Whitetail.........Had the Deer run at the sight of the Coyote, it is even money that on the slippery, snowy surface, the Coyote might have been able to leap onto the deers back initiating a killing neck bite...........Not so the case with the deer wisely matching the coyotes circular movements and keeping the canid in front of him

Coyote takes on a deer in a snowy standoff (VIDEO)

BY Earth Touch News MARCH 30 2016Coyotes might be known for raiding the occasional garbage bin, but the underrated canids are more than just pesky scavengers. They're also skilled hunters who will take on just about anything they can find. This usually means rabbits, snakes, squirrels and other small prey – but one lone ranger in Maine decided to go for the gusto when it attacked a passing deer.Whitetail Deer holding ground against a lone Eastern Coyote

Unlike the populations on North America's west coast, Eastern coyotes are known to eat quite a bit of venison – especially during the winter months. It's possible that this shift in diet has more to do with food availability than a taste for deer. The large prey are more vulnerable during the harsh winter, and tend to collide with vehicles more frequently.The Deer might escape the Eastern Coyote but there is a better chance for the Coyote to jump on the Deer and deliver a killing bite

While some suggest the coyotes are merely scavenging deer carcasses, hunts like this one suggest that at least on some occasions, these carnivores will take on a challenge. Onlookers who witnessed this particular standoff were surprised at the deer's vigorous defence. 

Coyotes will kill fawns within first few weeks after they are born

Find yourself wondering why this coyote was hunting during the day? It's actually a common misconception that these animals emerge only at night. Sightings of coyotes are most likely in the hours just after sunset, but in areas where pesky humans haven't encroached on their habitat, they'll happily roam during the day. 

Unfortunately for this hungry hunter, dinner will have to wait.
