psittacine beak and feather disease
occurs predominantly in young birds with their first contour feathers, but sometimes adults with previously normal feathers.

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.
