Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in Arctic, yet region remains one of most remote and difficult to study. Researchers have increasingly relied on animal tracking data these regions understand individual species' responses, but if we want larger-scale change, need integrate our understanding across species. Davidson et al. introduce an open-source archive that currently hosts 15 million location points...
Tracking studies are often used to inform conservation plans and actions. However, species have frequently only been tracked in one or a few localities, whereas space use can be remarkably flexible, especially long‐lived with advanced learning abilities. We assessed variability the Critically Endangered Hooded Vulture Necrosyrtes monachus by pooling movement data from three populations across species’ sub‐Saharan range (in South Africa, Botswana, Ethiopia, Kenya, The Gambia Mozambique)....
Large gulls are generalist predators that play an important role in Arctic food webs. Describing the migratory patterns and phenology of these is essential to understanding how ecosystems function. However, from all six large gull taxa, including three long-distance migrants, date seasonal movements have been studied only with small sample sizes. To document flyways behaviour Vega gull, a widespread but little-studied Siberian migrant, we monitored 28 individuals GPS loggers over mean period...
Since 2009, we have been determining blood lead levels (BLLs) for Eurasian black vulture (EbVs, Aegypius monachus) in Mongolia. EbVs migrated from Mongolia to the Republic (R.) of Korea 2012, started comparing BLLs Korean birds [Mongolia; mean = 2.72 ± 0.09 μg/dL standard error (SE), n 181, R. Korea; 6.68 0.58 SE, 124]. In also analyzed by free-ranging (mean 7.54 0.50 44) rehabilitation center 6.21 0.86 80), and fed rescued water deer (Hydropotes inermis) 11.26 1.66 7) livestock 1.97 0.27...
We report on differential movement of adult and juvenile cinereous vultures (Aegypius monachus) in the northeast Asia. Adult remain Mongolia throughout year, whereas many migrate from their breeding grounds to wintering Republic Korea (South Korea). trapped Cinereous Vultures attach wing tags (n = 270 fledglings 10 adults) and, for some, global positioning system telemetry units 31 fledglings, 18 juveniles, adults). While birds never left Mongolia, juveniles wandered more widely into Russia...
The present study was conducted to elucidate the movement and home range of 7 subadult cinereous vultures Aegypius monachus during wintering summering periods using a telemetry system from January 2015 March 2017 in East Asia. In total, 7053 locations (180?1607 points per bird) were used analyze size distance birds wintering, migration, periods. tracked overwintered South Korea. They migrated between Korea Mongolia spring autumn, respectively. Their varied considerably throughout annual...
Although organophosphates and carbamates are the most widely applied insecticides associated with mass killing of birds, little is known their sublethal effects. One well-known result exposure to toxin, conditioned taste aversion, was tested in a series field experiments which independent replicates were large numbers breeding territories Red-winged Blackbirds (Agelaius phoeniceus). While birds freely consumed untreated insect prey offered them control territories, those treated up three...
This study was conducted to determine the distribution and breeding status of black-faced spoonbill (Platalea minor) for conservation management purposes in South Korea. Breeding stopover sites were mainly uninhibited islets off west coast Korean Peninsula; wintering observed on Jeju Island. Between April July 2013, we 638 nests along Peninsula. Most Gyeonggi Bay area, Kujido Islet, Bido Namdong retaining basin, Youdo Suhaam Seomando Maedo which major these birds. It is essential understand...
Waterbird survival rates are a key component of demographic modeling used for effective conservation long-lived threatened species. The Swan Goose (Anser cygnoides) is globally and the most vulnerable goose species endemic to East Asia due its small rapidly declining population. To address current knowledge gap in parameters Goose, available datasets were compiled from neck-collar resighting telemetry studies, two different models estimate their rates. Results mark-resighting model using 15...
This study was conducted to clarify the size of home range and movement distance juvenile black-faced spoonbills from post-fledging until fall migration using a Global Positioning System (GPS)-wideband code division multiple access (WCDMA)-based telemetry system along west coast South Korea. The (n = 3) 45.2 km2 in core area consisted 8.4 within Baeksu mudflat, Yeonggwang, Jeolla Province, Mean weekly distances were not significantly different (Kruskal–Wallis test, Z 3.47, P 0.18) among...
This study aimed to estimate the home range of Eurasian Eagle Owl (Bubo bubo) from May November 2012. Bubo bubo were rescued by Chungnam Wild Animal Rescue Center. WT-100 weigh 83g. Analysis ranges used a SHP File and ArcGIS 9.0 for GIS, Kernel Density Estimation (KDE) Minimum Convex Polygon (MCP) analysis. Home 39.1 km2 27.8 km 2 (KDE 95%), 20.9km2 90%), 4.2km2 50%). showed very similar results previous study. That is result opportunistic foraging tactics selecting prey.
This study addresses for the first time movement patterns of globally near‐threatened Bearded Vulture Gypaetus barbatus in its most important stronghold, high‐altitude mountain ranges Asia. Tracked individuals ( n = 8) Annapurna Himalayan range (Nepal) foraged over a vast 60 715.9 km 2 and our results indicated age‐class differences use space. Territorial adults showed very small annual home‐ranges (K90 150.3 ), whereas immatures wandered extensively covered mountains 23 930.8 ). For...
Mallard is a dominant waterfowl species wintered in Korea. We researched the mallard spring migration route, stopover sites, and breeding sites. used cannon nets Central Korea to catch attach 10 wild trackers (WT-200). The mallards’ departure dates were from end of March early April. route varied by individual mallards, with most moving through North Korean east coast. Breeding sites distributed among interior Northeastern China. average distance areas was 1,265 km [standard deviation (SD) =...
