[Objectives] In this study, we analyzed the time-activity budget of Baer’s Pochard (Aythya baeri) in different habitats during winter and the effects of human disturbance on the activities of Baer’s Pochard. [Methods] In December 2020, we used a focus sampling method to observe the behavior of Baer’s Pochard in Minquan Ancient Yellow River National Wetland Park, Henan Province. We used ANOVA to compare the significance of differences between behavioral states in different habitats, and t-test was used to compare the significance between the genders. [Results] The comparisons of habitat availability with habitat utilization among the seven types of habitat revealed remarkable differences in habitat selection (Fig. 1). The most utilized habitats areponds, open-water lotus ponds, and open water (Table 1). The results showed that the main behaviors of Baer’s Pochard were rest (44.4%), foraging (34.2%), locomotory (9.0%), and maintenance (10.1%). There were significant differences in foraging and resting behaviors among different habitats (Table 2). The proportion of foraging behavior in ponds (50.1%) was significantly higher than that in large-water lotus ponds and open water areas. The proportion of resting behavior (63.1%) in large-water lotus ponds was significantly higher than that in ponds and open water areas. There are some behavioral differences between males and females, the females’ foraging time is higher than males’, and maintenance behavior is lower than males’ (Table 3). All three habitat types have varying degrees of human interference (Table 4). The ponds were the most disturbed, and the main sources of disturbance were fishing, pedestrian, and construction, while the lotus ponds and open waters were mainly disturbed by fishing boats. [Conclusion] This study suggests that the conservation of Baer’s Pochard should take into account the ecological effect of different habitats and the tolerance of Baer’s Pochard to different disturbances, and take corresponding measures to carry out conservation actions.
