The vocalizations seem to favor both sides.
They can yip & yap and sometimes sound like hyhenas.
They will respond to a howler and the challenge & distress can work well.
Sometimes you would swear that you have a pack of wolves over there
When they open up.
I like to get their attention, but become increasingly subtle with the call (read coaxing)
When they get within 500yds and let them hunt me down.
In alot of cases I do not know they are there and will start light with a squaller, but then really pour it on hard in the prime time of after sundown to dusk.
P.S. Watch the Majors & Minors for your local as said by the Solunar Tables.
They really do seem to work. Sometimes I may be out at 1:00 in the afternoon.
