Publisher's Synopsis
The analyses of ring recovery information for almost 200 species are included in this book, which features: introductory chapters about the ringing scheme, migration ecology and study methods; a critical examination of potential spatial and temporal biases in the ringing-recovery information caused by ringing and finding circumstances; and variation in movement patterns across species, age classes, and sexes,;Texts for individual species, written by experts on their movements, feature not only information from the BTO ring recoveries database but also appropriate details of movements from other sources when possible (eg colour-marking programmes, radiotelemetry, surveys of migrants, radar studies). Each account includes locations, ages and seasonality of ringing, finding circumstances, movement patterns and timings for populations that breed or winter in Britain or Ireland or pass through on passage, information on the dispersal of immature and adult birds, fidelity to breeding and wintering areas, implications for conservation management, identification of gaps in current knowledge and recommendations for future ringing research. Overview chapters summarize the value of information from ringing for bird conservation and make recommendations for improving knowledge of movements in the future.
