Abstract: The white-vented myna Acridotheres javanicus population has declined from 229,000 in the 1980's to 139,000 in the 2000's. The total range (i.e. the area that includes all the locations where the bird is ever found) and home range (i.e. the area in which an animal spends most of its time while foraging, mating and caring for the young) of seven white-vented mynas were determined by radiotelemetry between 8 November 2001 and 14 January 2002 in Singapore. These were compared to the total and home ranges recorded for eight white-vented mynas in 1988 by Kang (1989, 1992). Both the total and home ranges were found to be significantly smaller in the later study (14.0±5.0 ha, and 4.0±1.0 ha, respectively). Possible explanations for the difference in range sizes include differences in transmitter-mounting techniques, differences in the duration of study and a possible impact of the rising crow population on the myna population in Singapore.
