In this photograph, the pigeon in front appears to have three wings because of the perfect placement of the other pigeon behind it. At the moment when this photograph was taken, the two pigeons actually seemed to be fighting (or dancing). The edges of the wings appear slightly blurry because the pigeons were flapping them violently during their fight (or dance). The motion of the wings led them to appear blurry in the photograph.
