| Abstract | Wetlands are crucial nesting areas for the little grebe (Tachybaptus ruficollis). Our study was conducted at awastewater treatment facility at Khon Kaen University in northeastern Thailand to determine whether human disturbance affectedthe breeding success of the birds at wastewater treatment ponds in 2011, 2012, and 2016. We found 14, 8, and 14 active nests in2011, 2012, and 2016, respectively. The results indicated that human disturbances likely caused the grebes to shift their nestlocations. In the 2011 and 2016 seasons, when human disturbance was low, the hatching success was 70%. In 2012, a weedcontrol program at the facility resulted in the dramatic hatching reduction to 9.7%. The results also indicated that some humanactivities, such as predation and habitat disturbance, could have dramatic effects on the nesting success of the T. ruficollis. |
