While camping out last Summer I spotted a Meadowlark playing peek-a-boo with me in the tall prarie grass. I took many shots, but most were almost impossible to tell there was a bird there. Meadowlarks are extremely shy birds and hard to get close to them. This is probably an Eastern Meadowlark, but beacause I live near the edge of the territories between Eastern and Western species, it could be one or the other.
