Résumé :	Numbers of many bird species which breed ore farmland, arid are reliant ore cropped land for feeding or nesting, declined between the 1960s and 1990s. In contrast, Chaffinch Fringilla coelebs numbers increased on farmland over the same period. This study investigates the ir fluence of both cropped and noncropped land on Chaffinches foraging for nestlings, nestling survival arid territory density. The study was carried out on nine mixed lowland farms in south Miti al England in 1996 and 1997. Chaffinches made little use of cropped areas when foraging for young (less than 9% of foraging visits, despite cropped areas covering 93% of study areas. Instead, trees and bushes influenced foraging patterns and breeding success. Extensive use was made of trees and bushes by adults searching for food for nestlings (75% of foraging visits were to hedges and trees within boundaries or fields, despite these areas covering
