摘要

Eared Grebes(Podiceps nigricollis) marked with small radio-transmitters in 1995 and 1996 at a breeding site in south-central British Columbia, were subsequently detected in fall Mono Lake(California) and Great Salt Lake(Utah). At least 50/100 of all marked birds were detected on Mono Lake, and data collected in mid-October suggested that this proportion was consistent across years. These observations largely confirm a fall migration pattern that has been previously based on leg-band returns.
