The Birds of London
The parks, reservoirs, rooftops and gardens of London, here defined as the area within 20 miles of St Paul's Cathedral, have a surprisingly rich avifauna, including a healthy population of one of Britain's rarest breeders, the Black Redstart. The region also has a remarkable list of rarities. In recent years Canary Wharf has proven to be a magnet for vagrants, while one of the very few British records of Tengmalm's Owl hails from Plaistow, an unfortunate bird stoned to death by local urchins in 1877.
Some species, like the Peregrine Falcon, Black-headed Gull and Ring-necked Parakeet, have seen their fortunes soar over recent decades; others, such as House Sparrow, have suffered a population collapse. While as recently as a century ago, the London area had breeding populations of birds such as Wryneck and Red-backed Shrike, which are now nationally extinct. The status, distribution and history of every species on the regional list is discussed in detail.
