I was driving along my country road, and saw some odd bird behavior on a power line along the road. I didn't know the bird, but it was singing, and then would jump abruptly up into the air about 3-4 feet, landing back where he started. I grabbed my camera a snapped some photos (although not realizing it was still configured for my late-night photos of the night before - sorry for the quality).

With the help of my bird books, I have identified this as a Northern Mockingbird, and it's known for such displays in trying to distract predators from it's nest. I'm not sure if that's what it was doing on this occasion (I wasn't much of a threat, in my car and on the ground), or whether it was grabbing some food (insect) on each leap. He let me snap 170 photos before he flew off.
