Packing up… I don’t think this is common in coyotes here in NY. BUT… I have personally witnessed this behavior with my own eyes exactly ONE time. From my vehicle I observed 2 coyotes hold the attention of a seemingly healthy doe whitetail that was feeding in a large field. This was in early October probably 20 years ago in Madison County NY along the 9 mile Swamp. The coyotes would separate slightly and skirt back and forth while keeping a good distance from the doe. 30-50 yards out in front of her. Occasionally moving towards her only to turn and retreat. It seemed very intentional, but who knows? The most interesting aspect was while this was happening, I observed a second pair of coyotes that were circling higher up and behind the doe and closing the distance. Also seemingly very calculated. I did not get to observe the results of their endeavors, as darkness was falling. It was very interesting to observe though.
Now, in the same general area, my cousin owns hunting land in Madison County, on the 9 Mile Swamp. Over the years I have caught on trail camera more than once, up to 6 coyotes together during mid to late winter months when it seemed like odd behavior for the time of year.
I have found more than once, adult deer remains. Only once was I sure that it was brought down by coyotes by the evidence in the snow over a large area. Did not appear to be a quick, clean kill! Many could have just been scavenged deer that died from other causes? Unrecovered hunting incidents. Vehicle hits that made it back into the swamp before dying, etc. Hard to determine the exact cause of death.
Like I said, I don’t think it’s common for pack mentality to occur in coyotes. I don’t know if this is just a coincidence that the same general area over a 20+ year span has coyotes that seem willing to tolerate one another at times of the year when you would expect them to be dispersed or paired. On my cousins property, in late February or early March of 2019 or 2020, I called in a quad. I only managed to kill one of the 4 due the a feeding issue with my rifle. A young male. They came in very aggressively to coyote vocals. Nothing odd about that, but quads at that time aren't all that common for me.
Biologists claim our eastern coyotes have more wolf genes than the western coyotes. Larger bodies, thicker skulls. Maybe their was a perfect genetic storm in this area that produced some wolfy acting coyotes? Maybe it’s some learned behavior that they pass along generationally to their pups like wolves or killer whales?
Just my observations. IDK? I don’t really care. I will shoot them without prejudice either way! Lol.
