Habits and Feeding. The House Sparrow Passer domesticus population in Britain suffered a major decline in the 1920s, particularly in built-up areas, which coincided with the replacement of the horse by the internal combustion engine.The mixed fortunes of House Sparrows since then are examined, emphasising that factors operating on farmland populations differ from those in towns and cities.
