They do take deer regularly. A couple of years ago while hunting VT I came across a doe skeleton in the fresh snow. There were parts of the animal scattered all over and we had 6” of fresh snow. There was coyote scat scattered all around and judging from the tracks there were at least 6 -10 yotes of all sizes. I back tracked the carnage and came to a spot where 2 deer were eating in a grown up field bordered by goldenrod bushes. You could see the yotes set up an ambush and must have rushed the deer from different directions. One got away but all the tracks led up to the one that was killed. They literally tore a whole front shoulder off the deer and the head/neck was severed. All the yotes must have divided up the kill because it was scattered over an area that was the size of a small house. All the bones were picked clean and there wasn’t more than a few scraps of hide left. Due to the snow fall I surmised that the kill occurred the day before.
