摘要:

SummaryThe paper describes the results from banding and retrapping, with some associated measurements, in two winter populations of Pied Currawongs in the Snowy Mountains. Yellow gape is an immature character; males are the larger sex and the body weight of mature and immature birds declines during the winter. The age grouping of recoveries is different for the two populations in a way which suggests that breeding birds are rather sedentary and large movements occur only among non-breeding adults and immature birds.
