During the the first week here in Wy, I was in the timber when I heard what sounded like elk moving through the timber below me. I sent out a churp, and heard a growl/huff down the hill. After about a minute I churped again heard the same noise. Then I spotted the elk, a herd of 3 cows and 4 calfs. After locating the lead cow, I saw her growl again. I managed to call all of them in bow range of my hunting partner, but he couldn't close the deal. (he missed ) Anyway, I have heard bulls do a huffing sound before, but never cows. The best way to describe it was it sounded very simular to a bear. Anyone else ever heard cows do this?
