I've posted about this behavior before.It has happened to me on numerous occasions ,you get a blazing fire going at night and if it is visible to the coyotes they will howl at the fire.I bring this up again because a friend of mine experienced this strange behavior.He said he was outside burning an old stump and it was visible from where the coyotes were and they began to howl at the fire.Maybe this is of no importance but I find it to be very interesting behavior.Has anyone else have this happen to then while camping or burning the trash at night?
