The cow calls you need to become familiar with are the- Lost cow call- Hyper hot or cow in heat cow call- Demanding cow call- Excited cow call- Social or herd talk cow call- alarm cow call- and the bark, this one you don' t want to imitate. Click on my Web site at bottom of post and you' ll hear the lost cow call being demonstated on Tip of the week page. Tomorrow morning you' ll hear Cow in heat call. I' ll show you what they sound like as well as when to use them. Hope this helps. elknut1.
