Thanks David for chiming in your feedback is better and more accurate than any survey or study done IMO
You hit on something that I forgot about and have seen videos of it coyotes taking moose in packs up there yet DNR says they don't or did indicate that
I think you are on to something with the low calf numbers being seen and the impact coyotes are having and as you know our coyotes are closer to wolves than coyotes so no issue for them talking moose calves even adults
I would say your guess is very accurate Just know something is going on different way beyond the usual jacking , rough winters etc etc since it is happening way too fast now the decline
Thanks again
Joe
Little bit on it here

Reliance on moose as prey led to rare coyote attack on human
Wildlife researchers have completed a study that may settle the question of why, in October 2009, a group of coyotes launched an unprovoked fatal attack on a young woman who was hiking in a Canadian park.
