摘要：

Changes in the plasma titers of FSH were investigated in a free-living population of barheaded geese over the whole year. Adult males had pronounced seasonal changes from prebreeding levels of .apprxeq. 20 ng/ml to a peak in the breeding season of .apprx. 300 ng/ml. Changes in females were slight. An increase from nondetectable, .apprxeq. 20 ng/ml to a mean of 32.2 ng/ml before egg-laying was found. The data are discussed with regard to the literature on free-living species and the previously published data on LH [luteinizing hormone] and testosterone levels in the same birds.
