Patience is very important. A suspicious bull in not likely to come charging in. A bull may approach quietly and slowly. Calling can often be used to confuse animals when you make noise that spooks them. A call at the strategic time can make the elk think that the noise they just heard and started to spook from is just another elk.
Confidence is also very important.
If you don't expect calling to work, chances are good that when you finally do call in an animal you won't be ready to make the shot. The quick, agile flight of a mourning dove can be a challenge for the best of shooters. Common in much of the state during the nesting season, most doves quickly migrate south with the first frosts or stormy weather. Early September hunting generally produces the best success. When selecting hunting sites, look for trees and brushy areas near water sources and agricultural lands.
