feeding areas/water should yield sightings
In Ontario, everywhere in moose country is a feeding area, and water is everywhere too.
IMO calling is questionable when on a calf hunt. Drives can be effective, once the moose are spooky, they move easier. Most of the calves we have shot have been shot by guys on stand, with only one I can remember shot by a driver. I remember two being moved by other hunters, two were simply encountered while walking in to the stand. All were with momma moose.
One story I've related before goes like this.
I was hunting out of a tent, with one other guy. We had my Dodge Caravan, and a trailer. Never did get an adult tag in that area.
I was walking up an old logging road, all grassed in, coming to a T in the road. Just before the T is a little hill. I see my hunting partners hat cross at the T over the hill. As I get closer, I see two moose following him down the road!
The calf is behind the cow, and I can't make a positive ID She spotted me, and turns away into the bush. I run like hell after her, making a quick silent gesture to my buddy, as he spins around, kinda bewildered. I get a positive ID, but no shot. I tell him to stay put, and I run like hell down the road towards our camp. The moose is running up the hill at this time, towards the main road. About half way to camp, I hear her turn, she's making a hell of a lot of noise, crashing through the bush. I stop, as I hear her coming back, and realize that I can see my van through the trees. She comes to the trail about twenty feet in front of me. The 338WM drops the calf so fast, that by the time I recovered from recoil, she was gone. Momma moose was not amused!
She stood over the calf, and refused to move, no matter what we did. Fired shots, we went in and rushed her, she bluff charged.
I decided I'd go get my camera, a Pentax SLR, and take some close ups, so I start to walk away. She starts for my buddy. He hollers for me to come back. We both go get the camera.
Now at the time, I had a pre-packed hunting suitcase, I used for everything. In it was a school bell I planned to use to get the guys up at deer camp. What the hell I thought, and I took it back to the moose.
You should have seen the reaction to that bell. Her eyes went big, and she freaked out, she swapped ends, and ran as fast as she could go, with me giving chase, ringing that damned bell, and dressed head to foot in orange.
It's real nice gutting a moose when camp is twenty feet away, and we hung it from a big tree near the outhouse.
That night my buddy woke me up. The shadow of a moose was clearly visible in the moonlight on the tent wall next to his cot, and then a bit of drool dropped on the tent above his head. Holy ####!
I reached out and tripped my Big Ben alarm clock, this was rewarded by the sounds of momma moose crashing off into the night.
When we got up, we found she had done a wonderful job, chewing back all the brush around the outhouse.
She did not return, but, the thought of what would have happened had one of those big feet come through the tent wall haunts me still.
