The nesting behaviour of birds is a critical aspect of their reproductive ecology, influenced by environmental, evolutionary, and behavioral factors. This study documents a notable shift in nesting behavior of the red-naped ibis (Pseudibis papillosa), a solitary nesting wader traditionally known to use tall trees, towards the utilization of anthropogenic structures such as power transmission pylons and communication towers. Field surveys conducted between March and April 2023 along National Highway 152, from Pehowa to Kaithal, Haryana, recorded 26 power pylons and 1 mobile tower supporting red-naped ibis nests. The nests, constructed primarily from twigs and leaves, were typically located on the crossarms of pylons at heights of 15-20 meters. Although multiple nests were observed on some pylons, only one pair of birds was seen nesting per pylon, consistent with the species’ solitary nesting habits. This behavioural adaptation may reflect a response to habitat modification, urban expansion, and the scarcity of traditional nesting trees. While these artificial structures may offer certain advantages, such as predator avoidance and reduced human interference, this shift raises important conservation concerns regarding the long-term viability of such nesting choices. The findings highlight the need for further research into the ecological drivers and consequences of this nesting shift in red-naped ibises.
