“…Black-necked crane populations differ in their migration patterns. The average migration duration of the Nyingchi-Qinghai population (spring: 8.6 days, autumn: 30.5 days) is similar to the previously reported values for the Yanchiwan-Linzhou population (autumn: 31.3 days) (Wang et al, 2020), and longer than the Ruoergai-Dashanbao (spring: 5 days, autumn: 5 days) (Qian et al, 2009) and Shaluli-Napahai populations (spring: 1.8 days, autumn: 4.6 d) (Liu et al, 2012). The migration duration of the Bhutan-Shenzha population is unrepresentative, as only one crane was fitted with a satellite transmitter (Archibald, 2005).…”

“…The migration duration of the Bhutan-Shenzha population is unrepresentative, as only one crane was fitted with a satellite transmitter (Archibald, 2005). The average migration distance of the Nyingchi-Qinghai population (spring: 1,183 km, autumn: 1,456 km) was shorter than the Yanchiwan-Linzhou population (autumn: 1,500 km) (Wang et al, 2020), but longer than the Ruoergai-Dachanbao (spring: 651 km, autumn: 694 km) (Qian et al, 2009), Bhutan-Shenzha (spring: 480 km) (Archibald, 2005), and Shaluli-Napahai populations (spring: 256 km, autumn: 219 km) (Liu et al, 2012). Breeding/summering and wintering sites are connected by migration routes (Qin, Chen & Xiang, 2008;Rappole, 2013), and previous studies have shown that altitude is the most important factor affecting crane breeding/summering and wintering habitat selection (Han et al, 2017;Han & Guo, 2018).…”

“…The HQBP3622 transmitter weighed 22 g and was attached to the back of the birds using a Teflon strip. The HQLN0421 transmitter weighed 40 g and was attached to the left leg, and the inner diameter of the transmitter was 20 mm (Mi, Møller & Guo, 2018;Wang et al, 2020).

Background The black-necked crane (Grus nigricollis) is a vulnerable species and the only species that lives in the plateau. Five migration routes of different populations have been identified, but for cranes wintering in Nyingchi Prefecture, Tibet, the migration route and breeding/summering area are still unknown. The aim of this study was to investigate the spatio-temporal migration patterns of black-necked cranes in this area and to identify important areas for conservation. Methods In 2016, we fitted seven black-necked cranes in Nyingchi with GPS-GSM satellite transmitters to record their migration routes. We used ArcGIS 10.2 to visualize important stopover sites and the ‘ggplot’ function in R to analyze the migration patterns. Results From March 2016 to May 2019, we recorded nine spring migration and four autumn migration tracks from five individuals. Four individuals spent the breeding/summering season in Qinghai Lake, while the other spent the breeding/summering season in the Jinzihai Wetland of Dulan County, Qinghai Province. Detailed spatio-temporal information showed that the spring migration lasted 8.7 ± 4.6 days and covered 1,182.5 ± 90.4 km, while the autumn migration lasted 30 ± 10.6 days and covered 1,455.7 ± 138 km. Basom Lake and the Shazhuyu River were the most important stopover sites during the spring and autumn migrations, respectively. The cranes spent 4.4 ± 3.7 days in Basom Lake and 26.3 ± 10.7 days in the Shazhuyu River. The black-necked cranes mainly migrated during the daytime (>85 % of the fly points), and 81 % (17/21) of all stopover and roosting sites were in the valley or at lakeside swamps. Only 17.7% (516 / 2,914) of the data points for stopover and roosting sites were in protected areas. Main conclusions Our study revealed the breeding/summering areas and migration routes of the black-necked cranes wintering in Nyingchi. These results contribute to a better understanding of the annual spatio-temporal migration patterns and the development of conservation plans for this vulnerable species.

Despite previous research efforts, the majority migration routes of the black‐necked cranes (Grus nigricollis) have remained veiled. In this study, we utilized satellite telemetry data from 45 cranes between 2015 and 2021 to unveil critical insights. Our results revealed 11 distinct autumn migration routes and one sedentary flock, of which eight routes and the sedentary flock were previously undocumented. Our findings highlighted the remarkable diversity in the migration routes of black‐necked cranes, especially in terms of migration orientations, spatial–temporal patterns, and altitudinal movement patterns. Cranes breeding on the eastern, northern, and central Qinghai‐Tibetan Plateau migrated southward, while those on the northern slopes of the Himalayas migrated eastward, westward, northward, or opted to remain sedentary. Moreover, we expanded the known range of migration distances to 84–1520 km at both ends (excluding sedentary individuals) and identified two long‐term (Da Qaidam and Chaka) and one short‐term (Gyatong grassland) stopover sites. Furthermore, our study revealed that the breeding colonies in the Qilian Mountains on the northeastern Qinghai‐Tibetan Plateau utilized long‐term stopover sites before embarking on significant altitude ascent, while other flocks displayed more urgent migration patterns, preferring to roost only at night. By unveiling the near‐complete autumn migration routes of black‐necked cranes, our research has contributed to discovering the critical habitats and connectivity among various breeding colonies, which is instrumental in developing effective seasonal conservation plans.
