Resource utilization by the Kori bustard in the Serengeti ecosystem

Jan 19, 2021

The results indicated that males were
21.5% more mobile than females, and movements were 6.3% more diffuse during the nonbreeding period compared to the breeding period (7.59 versus 7.14, respectively). Contrasting models indicated that males preferred more open grasslands during the non-breeding
period and also preferred closed and shrubbed grassland during the breeding period.
Females preferred more woody vegetation during the non-breeding season compared to the
breeding season. The most parsimonious model indicated that females preferred to stay
closer to rivers and diverse areas during the non-breeding period whereas males preferred
areas that were farther from rivers and homogenous. Homogeneous areas were preferred
during the breeding period, and heterogeneous areas were preferred during the non-breeding period. We conclude that the movement behaviours of Kori bustards changes with the
season and habitat. Further research is needed to understand the factors driving the seasonal movement of Kori bustards in the Serengeti ecosystem.
