One or two resident moose can make a lot of tracks . Did you do your pre-season scouting ? Is the rut over , just starting ? Many bulls in the area , you can usually tell by the tracks . Cow calling only ? That's enticing to a bull but if the rut is on , challenge him . Don't overdue the calling . Grunt , snort and burp like a bull and pick up a stick and smash the underbrush . Sounds like two bulls shoving eachother and fighting in the rut . Larger bulls will come in to run them off and smaller bulls will come in to watch . Cows often come in to watch also . If it's quiet down by the river give a couple of long drawn out cow calls . Splash the water to make it sound like the cow is walking in the water . Use a can or bucket and pour a half gallon of water slowly in the river from 4 feet high to simulate the cow pissing . Bulls like that . After a couple of cow calls wait a few minutes and then give a couple of bull grunts . If another bull hears it he'll want to get to the cow first . If the primary rut is winding down there is a secondary smaller rut where the younger bulls try to get some so calling will usually work for at least two weeks but you have to be in an area with a decent moose population and not just a bunch of tracks that two resident moose could have made . I'd suggest that if your calling is good and the rut is on set up one place in the early morning and if nothing happens move a mile and set up again for the late afternoon and evening . A bull call should sound somewhat like a bull , same for a cow but like your voice and mine are different , same for moose . The biggest mistake is calling too much . Don't worry about making too much noise because when a bull is walking through the bush burping you can hear him for 200 yards breaking branches and stepping on twigs . You should sound like that .
A bull will burp as he's walking through the bush , horny as hell , wondering around looking for a beautiful cow . The burping usually changes into short grunting if he senses a cow in the area or another bull . Snorting is usually aimed at another bull . Think of cattle bawling for your cow call and combine it with splashing and pissing . Break some branches and make some noise when you are bull calling to simulate fighting or just walking through the bush .
I've shot a lot of moose and these are a few things that have worked for me . Best of luck as i hope some of it will help you . Maybe some of the other guys will chip in with a few more tips . If you are road hunting that's pretty much 100% luck to be in the right place at the right time but lots of guys are very successfull with it . If you are properly calling in the rut in an area with a decent moose population it's now 75% skillfull hunting and 25% luck and usually very successfull .
