We investigated the impact of 16 wind power generators on the Mountain Hawk-Eagle Nisaetus nipalensis during the pre-construction, post-construction, and pre-replacement stages of new wind power generators, 18 years after the construction of the existing generators. Two pairs were observed during the pre-construction stage, three pairs were observed during the post-construction stage, and four pairs were observed during the pre-replacement stage. During the pre-replacement stage, two of the four pairs （pair A and B） were succeeded in breeding and other two （pair C and D） were not observed to be successful, even though many breeding behaviors, such as courtship displays, mating behaviors, and delivering prey were observed. Of the pairs confirmed the pre-replacement, pair A included an existing wind power generator located 553 meters from the nest site, and pair C included an existing wind power generator located 925 meters. Pair A was also succeeded in breeding. Additionally, within the breeding territory, pair A included 2 existing wind power generators, and pair C included 5. This indicates that all pairs continue to occupy their breeding sites in areas where existing wind power generators are in operation, it is thought that Mountain Hawk-Eagles can occupy their breeding sites near the wind power generators in this area.
