We identified Black-necked Cranes’ winter roost and foraging preferences of Black-necked Cranes in Bhutan during the winter of The results showed the depth distribution of invertebrate was significantly negatively correlated with mean temperature and mean of minimum temperature and was positively correlated with the number of days during which the ground was frozen (Table 4). d˪�ڪ�m��|�J՚� 4ީ���j��[�H��U�wx����]Y�z^6�n�~�~��*�67v�[��C�t� ]�@�4�h9|B�_��J��o�,xp> �Y The areas of the sampling sites were calculated using Arcgis 9.2 (ESRI Inc., Redlands, CA, USA). To further ease the conflict between cranes and local farmers, it is advisable to cultivate crops in a certain area that may be left unharvested for the cranes to eat. << Our results support previous reports that Black-necked Cranes generally prefer farmlands, and avoid grasslands (Kong et al., 2011a), likely due to the availability of domestic crops and invertebrates to feed on, as well as other habitat features. g�(�0�e��=�km�K�$��-�# R~+���NZFh_��������x*����YaO�4�er@�n ��u��<=����z�4I��X0�l��n��Zfy~C��./U�-s�]�SpI64�z[5n�� ���$Y��26I���l�תU5�dx�#@� ����Y`'�����W�-4��a��i3���,�U��[���l +ͩg@�f� Monthly availability of biomass of all food in the Dashanbao National Nature Reserve, China. 5 Monthly, yearly and two-year combined percentage of food types in the dietary composition of the Black-necked Crane. Given the mosaic landscape of the Dashanbao Reserve, the sampling sites for food availability were selected based on two criteria: (1) The site needed to include a large section of farmland and grassland bordered by farmland with three types of crops in cultivation in the transects. 72.90 4.87 In November (both years combined), the proportion of grains consumed was the lowest compared to other months. “In Bumdelling, there has been both human pressure and natural factors, which led to the decrease in the number of crane population,” Jigme Tshering said. By offering homestay services, she earns more than Nu … Black-Necked Crane festival is a good source of income for the locals. The first two axes of the CCA explained 96.6% of the total variance in food selection data and food variables, of which 93.8% was contributed by the first axis, and 2.88% by the second axis. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. We videotaped the birds for 5-min intervals each along all transect routes. We recommend that the protection administration should supplement additional foods for cranes during the cold-weather periods, and restore grassland foraging habitat. The idea is to help conserve both the rare cranes and local communities. With video observation, we were able to directly estimate the frequency on which a particular food type was fed on, without concern for variations in digestibility. Grain consumption was lowest in November but higher from December through February. Unfortunately, as a result of the 14 It is 139 cm (55 in) long with a 235 cm (7.8 ft) wingspan, and it weighs 5.5 kg (12 lbs). In addition, grain consumption was negatively associated with invertebrate availability. According to a study published in Zoological Research, the total population of the black-necked crane as per the 2014 survey for Ladakh is 112, which includes 17 breeding pairs. It is a resident species across the Indian Subcontinent and Southeast Asia with a disjunct population in Australia. 82.51 Invertebrate (%) In contrast, grains were consumed less than in other months. no more than one email per day or week based on your preferences. S1). The black-necked crane is endemic to China's Tibetan Plateau. of video recordings Through telemetry and banding data, it has become clear that the birds using the Eastern migratory route (in the following referred to as the Eastern Black-necked Cranes) breed in northern Sichuan and southern Gansu provinces and mainly winter in northeast Yunnan and southwest Guizhou (Li & Li, 2005; Qian et al., 2009). Again, the variable with the highest significant contribution was included. For Aum Sangay Dem, an elderly woman and the owner of a Homestay in Khewang village, Gangtey, crane conservation has been a windfall. This pattern leaves an obvious disturbance of the turf that can be used for identification (see Figs. The black-necked crane (Grus nigricollis) is a vulnerable species, breeding exclusively on the high-altitude wetlands of the Qinghai–Tibet Plateau. Thousands of new, high-quality pictures added every day. These studies largely reported a wild plant diet (leaves, roots and tubers), while failing to mention the inclusion of domestic crops or invertebrates in the diet of cranes in the Dashanbao Reserve (Liu et al., 2014a). Such an exhaustive survey is the fi rst ever to be conducted in all the 22 wetlands in this region. The Black-necked Crane (Grus nigricollis) is listed as a globally threatened species by the International Union for Conservation of Nature (IUCN) and is one of the most threatened cranes worldwide (Li 2014).Among the 15 known crane species, the Black-necked Crane is the only species that lives on plateaus year round. Height. The mean annual precipitation is 1,165 mm (Li & Zhong, 2010). (2) Digging up the soil to find and consume underground food, such as roots or tubers (including potato and turnip) (see Video S3). >> Dec Celebrating the festival together with the locals will let us experience Bhutan’s rich culture firsthand. Individuals can grow to 6000 g. Reproduction is dioecious. Subsequently, Bonferroni techniques were applied to correct the level of significance of the index. 0.93 Regional cooperation for conservation of the Black‐necked Crane. Food is the factor determining the long-term survival of Black-necked Crane (Liu et al., 2014). S5). by ; November 12, 2020; The destruction of the wetlands of the lower valleys where it spends the winter has entailed a decline of the species, which now … 1.49 20.84 These nutrients are essential for their migration fitness and overall survival. Stars indicate the sites of food availability sampling. The new discovery. 8 Its courtship, mating and nesting period extends till late October. The black-necked crane roosts at night by standing in shallow areas of streams or ponds where it can hear predators approaching through the water. The study area covers 19,200 ha and is a warm, humid plateau with a monsoon climate characterized by cool, wet summers and cold, dry winters. In Bhutan, winter residences of these birds are Phobjikha under Wangduephodrang and Bumdeling under Trashiyangtse. Demoiselle Cranes (Anthropoides virgo) (Sarwar et al., 2013), Florida Sandhill Cranes (G. c. pratensis) (Rucker, 1992) and Common Cranes show similar preferences for invertebrates (Avilés, Sánchez & Parejo, 2002). Listed in Schedule I of Wildlife (Protection) Act 1972 and as Endangered on the IUCN Red List. Black Necked Crane is found in the Palearctic and the Indo-Malayan Realm. 8.23 Latest research shows that more than 800 black-necked cranes are now there. Bird species harbor diverse communities of microorganisms within their gastrointestinal tracts, which have important roles in the health, nutrition, and physiology of birds. This information may facilitate the development of strategies to protect the Eastern Black-necked Crane, whose largest population winters in their most important wintering sites in the Dashanbao National Nature Reserve on the Yunnan–Guizhou Plateau (Li & Yang, 2002; Qian et al., 2009). It has black primaries and secondaries. 9.03 While, video observation enables the detection of even highly digestible food, it is often more difficult to identify the specific food types that are seen consumed. These results are similar to those of a previous report in which fecal analysis was used to study the crop and wild plant consumption of a subpopulation of Black-necked Cranes wintering at the Yarlung Zangpo Valley National Natural Reserve. The food selection-environmental correlations for the first two axes were 0.986 and 0.714, respectively. N 3.59 Find black necked crane stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. The Black-necked Crane is the last discovered of 15 species of cranes in the world. The annual Black-Necked Crane festival is celebrated at the courtyard of Gangtey Goenpa in Phobjikha valley. Nov Jan Wild grasslands were comprised of meadows with minimal water (Kong et al., 2011a) and dominated by orchard grass (Dactylis glomerata), bluegrass (Poa annua), Leontopodium, Trifolium, Pterospermum heterophyllum, Pedicularis densispica, Luzula multiflora, Hemiphragma heterophyllum (Kuang et al., 2008). In the colder months, starting from October, thousands of black-necked cranes migrate to the southern and central parts of Tibet. 32 0 obj To support further studies on population genetics and genomics, we present a high-quality genome assembly based on both Illumina and nanopore sequencing. It is important to note that initial estimates approximated that 13.96% of the Dashanbao Black-necked Crane’s diet would consist of invertebrates. reported 20 black-necked crane nests at Longbao in 1994 and 75 to 80 adult black-necked cranes at Longbao in late May 1996, including 25 nesting pairs (Wong 2002). 0.64 /Filter /FlateDecode S4). Forktail: 125-129. Following a preliminary canonical correlation analysis (CCA), we eliminated collinear environmental variables with high variance inflation factors (VIF > 20) from further analyses. Cover: The black-necked crane arrives in Ladakh in late March or early April to breed. A much smaller proportion of the diet was comprised of During colder weather (December or January), the invertebrate shortage is exacerbated. The black-necked crane is a resident of Inner Asia—the regions of Xinjiang, Tibet (and the Chinese provinces carved out of it, namely Qinghai and Gansu) as well the Chinese Proper provinces of Sichuan, Yunnan and Guizhou. China Crane News 6(1): 24-25. DOI: 10.7717/peerj.1968/table-1. ° The study area covered most of the foraging sites of Black-necked Cranes. 8 The valley is one of the most beautiful in Bhutan. Discover the rich culture of Bhutan, and attend the unique Black Necked Crane Festival. 1.35 This new discovery has raised new concerns on the health, safety and long-term survival of the endangered species. This would greatly enhance our understanding of the dietary habits of this species. Grain (%) Black-necked cranes Grus nigricollis in Bhutan: migration routes, threats and conservation prospects. Invertebrate availability (0.77), potato availability (0.65) and grain availability (0.53) were positively associated with the first axis, while the distributed depths of invertebrate (−0.78), the depths of potato (−0.68) and the depths of grain (−0.49) were negatively associated with the first axis. 50 Winter diet and food selection of the Black-necked Crane Grus nigricollis in Dashanbao, Yunnan, China.

More than 50% of the wild populations of this species are currently suffering due to significant habitat destruction resulting from grassland degeneration (Li & Li, 2012) and conventional agricultural practices that have decreased the diversity of available food types for this species in northeast Yunnan. However, little is known about Black-necked Cranes’ habitat requirements or the causes of their population decline. Holding a special place in the hearts and folklore of the Bhutanese, the black-necked crane is also known as the ‘Thrung Thrung Karmo’ in Dzongkha. The black-necked crane is revered in Bhutan as a symbol of longevity and the annual migration is a cause for great celebration, as residents mark the passing of … The Administration of ZhaoTong Forestry Bureau approved our study on behavior observation and food availability sampling in the research plot in Dashanbao National Nature Reserve (IDZTL2008163). 5,808 The black-necked crane (Grus nigricollis) which inhabits high-altitude areas has the largest body size of the world's 15 crane species, and is classified as threatened by the IUCN. Dawazam, 48, is one of the leading lights of the Black-Necked Crane Festival, an event created and launched in 1998 with the sole aim of pulling in tourists. 0.25 Total year Monthly trophic diversity was estimated using Shannon’s diversity index: H′ = − ∑Piln(Pi) (Pielou, 1966), where Pi represents the proportion of each food type. Canonical correspondence analysis (CCA) with biplot scaling on inter-species distances was used to display the relationship between food selection structure and the 6 environmental variables (main food variables). We walked transects once per day and switched direction of travel on subsequent days. black necked crane food. 0.50 One-way ANOVA indicated significant variation on monthly diversity of the diet (F = 25.00, df = 3, N = 8, P = 0.005). In contrast, the highest consumption of potato and invertebrates occurred in November, followed by January (for potato) and February (for invertebrates), while the lowest consumption for both food types occurred in December. The black-necked stork (Ephippiorhynchus asiaticus) is a tall long-necked wading bird in the stork family. For this purpose, we used video recordings and sampling of food availability to examine the dietary composition and temporal variation in food selection of Black-necked Cranes wintering in the Dashanbao National Nature Reserve, China. Phobjikha is one of Bhutan’s few glacial valleys, and chosen winter home of black necked cranes (November – March) migrating from the Tibetan plateau. ° Since Black-necked Cranes are highly vigilant and the landscape of the Dashanbao Reserve consists of rolling hills and valleys, we were unable to adequately observe the flocks from our vehicles along the main road in the Dashanbao Reserve and we had to walk along smaller roads. A total of c. 1,200 Black-necked Cranes winter in the Dashanbao Reserve every year, feeding on agricultural farmlands, as well as wild grasslands (Kong, 2008). 1 Nov The Black-necked Crane’s diet consists primarily of domestic food crops such as grains (74%) and potatoes (8%), in addition to invertebrates (14%). 1,502 The following information was supplied relating to ethical approvals (i.e., approving body and any reference numbers): The following information was supplied relating to field study approvals (i.e., approving body and any reference numbers): The Administration of ZhaoTong Forestry Bureau approved our study on behavior observation and sampling collection in the research plot in Dashanbao National Nature Reserve (IDZTL2008163). The video was taken at 12:46 on December 14th, 2014. Potato (%) There are seven main habitats of black-necked cranes in the nature reserve, and those who arrived have mainly gathered at wetlands and swamps on the east, south and southwest. Liu, Q.; Wang, K.; Yang, X.; Li, F. 2010b. Thus, understanding the Black-necked Crane’s dietary habits, food preferences, and the associated factors will facilitate the development of effective conservation plans for the protection of this vulnerable species. We only counted invertebrates larger than approximately 4 mm because that appeared to be the minimal size consumed by the cranes. For our analyses, we used the mean daily temperature and the mean minimum daily temperature. It is possible that cranes prefer domestic crops or animal matter over wild plants because (1) herbaceous plants may have lower caloric content than grains or animal matter; (2) there is insufficient density of vegetation suitable for the cranes to forage preferred species such as Pedicularis, Stellaria, Polygonatum and Veronica (Kong et al., 2011; Liu et al., 2014a). The variables we included were the distributed depths of grain, the depths of potato, the depths of invertebrate, grain availability, potato availability, and invertebrate availability. Black-Necked crane flies from Tibet to Phobijikha Valley in Gangtey during the winter season. The Black-necked Crane or Tibetan Crane (Grus nigricollis) is a medium-sized crane native to Asia. The black-necked crane lives at high altitudes in the Tibetan plateau, India and Bhutan, the only species of the crane family to occur in such habitats. 27 An additional count from the records of the Longbao Nature Reserve found 108 black-necked cranes at the reserve in July 1998 (Li 2004). Invertebrates were the second preferred food type in November and February. Moreover, we take part in the celebration of the Black Necked Crane festival in Gangtey. �ڪ�v U�n��Zf!�:ӥ���C�B�A�]bW��T&: Each eponymous black neck is elegantly supported by a proportionate greyish white body, with the white feathers turning to black at the tips of the wings and tail. Grain selection was positively correlated with invertebrate depth and negatively correlated with invertebrate availability. Black Necked Crane has parental care (pair provides care). ″ The available biomass of grains in November and December was higher than that in the other two months (Table 2, Nemenyi test, Nov. vs. Dec.: H = 1.14, P = 0.29; Nov. vs. Jan.: H = 7.53, P = 0.006; Nov. vs. Feb.: H = 13.60, P = 0.000; Dec. vs. Jan.: H = 3.92, P = 0.048; Dec. vs. Feb.: H = 6.46, P = 0.010). 5.81 This method provided a simple, minimally invasive manner to directly observe the feeding behavior of the threatened bird species in order to estimate their dietary composition (Newton, 1967; Price, 1987; Yoshikawa & Osada, 2015). Since tubers are too bulky for cranes to swallow, they peck at them repeatedly, swallowing smaller pieces, until the item is completely consumed. 2017) and show more territorial behavior and loyalty to their used foraging sites (Yang et … Thus, a mosaic of patches of cereal, potato and turnip characterizes the farmland, with each occupying about the same surface area each year. 0.01 Cranes consumed only a minimal quantity of wild plants despite their larger proportion of available biomass as compared to that of domestic crops and animal matter (Table 2). ���RՃk$l+����3 ���Pϵ�s�X�ں�0̜;��J�ծPeK �c@�./1�re'��o^�L��n�g��v'0ٚ� ��j���ȦfB��1���}�Z�iEw®�w��9 ��u �b4��kUMбV��F>�:�Tx8k�b�� 1Ē�K؟]e:F��_þ���{B�,pk+�qȪ* [}H�Љ��X�Z�j�{�u���~¦��Mx�b���CU( F1�_�t ����%s��8f��c拽c�={�[��bT'���p����V��= �����L��.�,��2�IX�\W�j(� � Jan 0.04 These updates will appear in your home dashboard each time you visit PeerJ. The cranes have been reported to forage on Pedicularis, Stellaria, Polygonatum and Veronica (Kong et al., 2011a; Liu et al., 2014a). During this time, the cranes were undisturbed and at a maximum distance of 80 m from our point of observation. In winter, the groups arrive and leave the feeding grounds together, but may split into family groups, each group keeping their own small feeding territories in a big marshes or fields. 0.00 1,212 When we pooled yearly data, domestic crops and animal matter accounted for 95.61% in total food items, of which grains accounted for 73.81%, potatoes 7.84% and animal matter 13.96%, respectively. Based on the results of our CCA, the grain selection and invertebrate selection present two different patterns. 7.16 Black‐necked Crane (Grus nigricollis), by assessing the relationships between foraging habitat selection, vegetation structure, livestock dung, and arthropod abundance within the dung itself. Invertebrate biomass was higher in November and February than that in the other two months (Table 2, Nemenyi test, Nov. vs. Dec.: H = 7.55, P = 0.006; Nov. vs. Jan.: H = 4.56, P = 0.033; Nov. vs. Feb.: H = 0.02, P = 0.888; Feb. vs. Dec.: H = 8.38, P = 0.004; Feb. vs. Jan.: H = 5.23, P = 0.022). Dec The Black-necked Crane’s diet consists primarily of domestic food crops such as grains (74%) and potatoes (8%), in addition to invertebrates (14%). Individuals can grow to 6000 g. Reproduction is dioecious. They often forage together in small groups, probing the ground for food. p��7������'a�� � ���g��h�O�����;�b�����w0VR�Tĉ�V��P@` ����}r��gk������$ 貪l�Q�Z�5���F�[�TAє�Z�'y��uQ�կ��?��R�� �r�J�#���PtA�K����������qP������͏��ӫz�l�r�Us��CW�Y9��mu�Y��[H6� c����4�F�T�!��u��J�Z�J.�d`A�]���$D����o��S/`~`/�{�5G]l��y�? S2 and S3). 0.07 Feb Until now, fecal microhistological analysis has been the only method used to identify plant material consumed by wintering Black-necked Cranes (Li & Nie, 1997; Liu et al., 2014a). ° Zoologicla Research 35(S1): 197-200. In November when both grains and invertebrates were most available, invertebrates were consumed more than at any other time. For the purposes of this study, supplemental feeding by humans was ignored because only c. 3 kg of corn are fed to fewer than 50 cranes every day (Kong et al., 2011a), which would have little impact on the overall dietary composition and food selection for the cranes. IDENTIFICATION. Total year 1.40 Status. To examine the association between food selection and environmental variables, we used Canonical Correlation Analysis (CCA). Current research on the proportion of animal-based foods in the diet of Black-necked Cranes has solely focused on describing species (Han, 1995; Hu et al., 2002; Li & Li, 2005; Liu, Yang & Zhu, 2014b). Grains were most available in November and decreased through the winter, whereas invertebrates were more available in November and February than in December and January. 4.30 It is associated with freshwater habitat. ′ Canonical correspondence analysis (CCA) exhibited the relationship between environmental factors and grain selection, potato selection and invertebrate selection in different patterns (Fig. Depending on the types of food being eaten, and the peck frequency, four different types of feeding patterns were identified: (1) high pecking frequency and ingestion of all the target food quickly in farmland.
