So, it's already been done, and better.

Did White's Merlyn have a nest of mice in his hair? I'm not arguing but I don't recall. I know he kept dead mice and worms under his skull-cap, and at one point the Wart thinks Merlyn's hair (Merlyn still has his hat on at this point) at least shows signs that seem to indicate a large bird had been nesting in it.

At least White's Merlyn kept pyjamas for wiping off the bird droppings from his head, which got there when the wizard took off his hat and his owl might then perch upon his head.
