Agricultural intensification and the timing of breeding of Corn Buntings Miliaria calandra

摘要: Capsule In an intensively managed agricultural landscape, few females attempted a second brood. Aims To investigate the effect of modern farming practices on number Corn Bunting breeding attempts. Methods We compared timing by Buntings South Downs, West Sussex, with habitat composition within 150 m their nests. Results Breeding was earlier in areas containing winter-sown wheat and set-aside than spring-sown barley. Nests were when cereal crops near nest more developed. The presence unripe grain better predictor height crop. Double-brooding extremely rare re-laid after failures. Daily failure probabilities clutches increased during season, largely as result harvesting operations. Conclusions Changes availability uncultivated nesting may have reduced incidence double-brooding some...
