Just before dusk fell over London, the birds would start to appear. Sam says there were ‘swarms of them coming in low across the cemetery, heading for their roost in the trees just behind me. I’d keep having to duck.’ Ring-necked parakeets, an Afro-Asian species, are now well established in the wild in Britain – the result of escapes and deliberate releases from captivity – and they are thriving in London. Their winter roosts can be huge – Sam had checked out several before opting for this one. ‘There were probably 5,000 birds – the noise was amazing,’ he says. With a constant stream of arrivals squawking past in groups of 20 or30, Sam worked out the parakeets’ typical flight paths. He set up his kit, experimented with various techniques and realised they were coming close enough for him to use a wide-angle lens. With a burst of flash at the end of a long exposure to create their ghostly trails, Sam captured the essence of these eye‑catching aliens in the English urban landscape. By the time it was dark, an hour and a half after the first arrival, the fly‑past of thousands was complete.
