英文摘要 | 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 <3% of study areas). Oaks (69% of visits) and Willows (15% of visits) were found to be the most favoured species of free for foraging. In one year of the study, chick starvation was less frequent in;rests located ore field boundaries with Oak trees than ire crests on boundaries without Oaks. Successful nests also tended to be closer to Oak or Willow trees than those where nestlings starved. Territory density was not related to hedgerow structure, presence or absence of Oaks and Willows in field boundaries, or adjacent cropping. Our findings ore nest survival were supported by analysis of British Trust for Ornithology nest record data which revealed flint nests associated with trees had better brood survival rates than sites not located close to trees. The rise of trees and shrubs for feeding and nesting in the farming landscape and the ability to utilize unkempt hedgerows pray leave contributed to the ability of Chaffinches to persist ore farmland despite wide-scale agricultural change in recent decades. |
