Several different raptors, nearly always alone, are now passing over London on migration. Every year there are occasional sightings of a red kite, honey buzzard, marsh harrier, hobby or even an osprey either at Rainham marshes, Barnes Wetland Centre or possibly Regent’s Park.
Nesting now is all but over except perhaps for woodpigeons which may still be feeding their young. Sparrows are notorious for encouraging any lingering house martins to leave their nests so that they can move in. Other birds such as robins and blackbirds have already started marking out their winter territories. Robins may have already driven away their females and will not allow them back into their territory for the next three or four months. The robin that is left is still our most reliable singer, pausing only to stop and look at us with a questioning look, its head leant to one side and its beady eye looking straight at us.
