In a previous post I had mentioned Phinny’s forehead was looking quite bare.
He lost his feathers above his cere quite suddenly. In fact, the morning I noticed, my first thought was that he had been in a terrible fight, but then I realised he had spent the night in his cage on his own & not even he, Mr Trouble himself, could manage to fight on his lonesome. So the missing clump of feathers, as alarming as they looked, must simply be due to a moult.
Over the following days, his forehead looked rough. Very rough. Poor boy. But then the pin feathers started coming through & he returned to being his usual handsome, troublesome self.
