psittacine beak and feather disease

occurs predominantly in young birds with their first contour feathers, but sometimes adults with previously normal feathers. There is a loss of contour and down feathers over most of the body, often progressing to complete baldness. The upper and lower beak may also be involved with inflammation, abnormal elongation, uneven wearing and transverse fracture lines. The disease is caused by circovirus.
