A bird's nest in Mayfair

London is a big place, and it's hard to think of it all as home. We all have our parts of town that mean most to us, and for me that's the north and the east, and parts of the centre I know best. So I become a bit of a tourist in places like Mayfair. It's one of the city's richest parts with impressive architecture and plenty of displays of ostentatious wealth, which I usually look at with bemused detachment. Above, though, nature takes its course. It may be an old, empty nest, but it survives in a budding tree just around the corner from the Ritz Hotel (below).
