Every one knows that the magpie is a black & white bird but, in flight I noted a flash of blue. This made me determined to try and catch one in flight to see if my eyes were playing tricks.
Before shooting I studied typical flights and found they were usually short distance, considerable flap rate of the wings but, when comfortably airborne, the flap rate reduced and a short glide followed. Armed with this info, all I had to do was find the right subject.
I didn't have time to increase my focul length but I managed to freeze the action. Low and behold, there was the blue I had noted. Most of this colouring is covered when the bird is at rest as it is on the inside wing feathers.
