Glasgow has more or less exterminated the lovely house sparrow in the last 40 years

The house sparrow (Passer domesticus) has experienced a decline of up to 98% in the Glasgow area over the past 40 years. The small bird’s numbers have declined across the UK by about 70% since the late 1970s, and is categorised on the IUCN red list as having a “decreasing population”. RSPB Scotland and University of Glasgow researchers believe that changing urban landscapes and insufficient food are among the causes. The population is particularly suffering in city centres such as Edinburgh and London where it fell by 60% between 1994 and 2004.
