Cockatiels are notoriously easy to disturb at night. How’s this for a messy beak? This one likes pomegranate!

Normally if I hear a bird crashing around in its cage after falling off a perch at night, I’m going to think of a few possible causes:

1. Something has disturbed the bird.
2. The bird is having a night fright.
3. There is something medically wrong.
