What's going on here? - # 167

What's all this then? This is one of hundreds of dear, sweet green parrots (offspring of an escaped pair) who now live in (plaque??) certain parts of London. Down in Petersham they are less welcome because they have taken a liking to the taste of 17th century cement that binds the brickwork and the 17th century putty that retains the window glass. The parrots (bless them, they are soooo sweet) gnaw out the the cement and putty. They love it. If you enlarge the photo (click it) you will see the jagged edges of the brickwork. That's where the parrots have gnawed the mortar away.
