Horned Lark. My first sighting consisted 8/10 of finding the bird! I heard and recognized but didn't identify the calls coming from a farm field. I just knew the calls sounded like those of a prairie bird. Eventually my eye caught movement and I used my camera to seek out the several larks! They are impossible to see if you don't hear first.
