Using citizen science to investigate the role of productivity in House Sparrow Passer domesticus population trends

Although House Sparrows are conspicuous birds and can still be found cheeping away in many areas, their numbers have fallen sharply in recent years, leading to their inclusion on the Birds of Conservation Concern Red List. Declines are greater in urban than in rural areas, and in eastern and south-eastern Britain than in other parts of the country (where the population is stable or increasing).  A new study by the BTO has used data collected by volunteers participating in Garden Birdwatch (GBW), the Nest Record Scheme (NRS) and the Breeding Bird Survey (BBS) to investigate possible reasons underpinning these trends.
