Most of these sounds are probably coyote, but some sound a little different. Can someone verify? (*Added video, oops)

This video was posted today but he recorded it back in February at an RC airfield area and it features a ton of animal vocalizations. Some of the sounds are definitely canine but some of the sounds are a little different than what I'm used to for coyote. What is your thoughts? Is this just an exceptionally vocal band of coyotes?
