Terrestrial Nocturnal Roosting Behavior of Black-necked Cranes (<i>Grus nigricollis</i>) on the Yunnan-Guizhou Plateau: Active Choice or Forced Environmental Adaptation.

ABSTRACT: Nocturnal roosting sites are integral to bird habitats, with their use and selection by birds serving as indicators of behavioral adaptations to environmental pressures. Black-necked Cranes (Grus nigricollis), which typically roost in shallow water, have exhibited an unexpected "terrestrialization" of nocturnal roosting sites within their eastern wintering population of southwest China. Despite this phenomenon being documented since the late 20th century, research on terrestrial nocturnal roosting behavior remains limited, hindered by technological challenges. To address this knowledge gap, we combined GPS-GSM tracking data from 14 individuals monitored between 2015 and 2022 in northeastern Yunnan and western Guizhou with remote sensing imagery to systematically analyze their noctur
