Limber

I'm worried about the birds. Bird B in particular has suddenly started favouring one leg. He puts very little weight on his right leg/foot and limps around everywhere. Given that he can fly, and is extremely strong and agile (remember his inversions), it seems highly unlikely that he hurt himself. So this worries me. I resort to hoping that he did indeed have an accident, however unlikely, and strained a muscle, since I can't bear serious consideration of the alternative: a tumour pressing on the nerve.

This is an older photo from his more limber days.
