As the increasing of power transmission lines, pylon-nesting is widespread all over the world, resulting in major concern on its contribution on bird conservation and the adverse impacts on power grid. In this paper, we investigated the pylon-nesting performance of the endangered Crested Ibis (Nipponia nippon) in Shaanxi Province, China. We also analyzed the impacts of pylon-nesting on the post-juvenile movement as revealed by GPS tracking, and presented suggestions to improve the safety of pylon-nesting birds and power grid. Since the first pylon-nesting of Crested Ibis discovered in Xixiang County of Shaanxi Province in 2018, a total of 7 pylon-nesting attempts on 4 pylons have been recorded till 2020 (Table 1, Fig. 1, Fig. 2a, b). Compared to tree-nests, pylon-nests were relatively higher (16.3 ± 7.2 m, n = 4), closer to human disturbance, such as motorway (140 ± 66 m, n = 4) and settlements (162 ± 95 m, n = 4), and farther from paddy fields (235 ± 79 m, n = 4), the dominating feeding habitat. The breeding productivity of pylon-nests averaged 2.33 ± 0.52 (n = 6), much higher than that of tree-nests. It is probably because pylon-nests are more resistant to strong wind and less accessible for natural enemies such as Siberian Weasel (Mustela sibirica) and snakes (Fig. 2e). Given there were many unoccupied nesting trees available nearby, we suggest the pylon-nesting of Crested Ibis is not derived from competition of limited natural nesting resources. GPS tracking of one pylon-nest born individual revealed a much shorter post-juvenile dispersal distance (2.0 km) than that of tree-nest born individuals, and the core home range in the first year covered the natal site and three power lines (Fig. 3); In the second and third year, although the bird made significant dispersal (15.5 km and 15.3 km, respectively), it still regularly returned to natal site and stayed nearly one month during summer. This indicated a deep imprint of the pylon-nest born Crested Ibis on its special natal habitat and might consequently leading to a higher possibility of nesting on pylon in the future. Based on the pylon-nesting records and the high reuse rate of pylon-nests during 2018﹣2020, we suggest pylon-nesting of Crested Ibis is not an occasional phenomenon, and might increase by year in the future and cause potential risk on the power grid security. The pylon-nesting of Crested Ibis once caused short circuit in May 2018, and the nestlings were successfully moved to an abandoned nest of Common Magpie (Pica pica) on the same pylon (Fig. 2b﹣d) and fledged later, which provided a feasible conservation measure. We also suggest to install perching frames and artificial nests on pylon beneath power line so as to both provide safety nest sites for Crested Ibis and reduce the damage to power line.
