Background: The Emei Shan Liocichla(Liocichla omeiensis) is a globally vulnerable babbler, endemic to southwestern China. We investigated its nest predators, nest-site selection and nest success at the Laojunshan National Nature Reserve in Sichuan, China in order to identify the precise nesting-habitat requirements of the species, and to test whether the nest-site-selection cues, preferred by the Emei Shan Liocichla, are positively associated with nest ***: We used infrared cameras to determine nest predators. We compared the microhabitat attributes between nest and random sites, as well as successful and failed nests. We used Binary Logistic Regression to determine the most important variables affecting nest-site selection of the Emei Shan Liocichla. We used the nest survival analysis in Program MARK to estimate daily nest survival rates(DSR). Nest success was calculated using the Mayfield ***: In total 56 nests were found. The DSR for all nests that contained at least one egg was 0.9564 ± 0.0091(95 % CI 0.9346–0.9711)(n = 40), while the total nest success was 27.5 %. We identified four categories of predators in 10 nest predation events, i.e. squirrels(n = 5), snakes(n = 3), raptors(n = 1) and wasps(n = 1). We found that:(1) nest predation was the primary reason for nest failure of the Emei Shan Liocichla,(2) tree cover, bamboo cover, liana abundance and distance to forest edge or gap were the most important variables affecting nest-site selection of this species, and(3) the nest-site-selection variables we measured appeared not to be positively associated with nest ***: Our findings suggest that the Emei Shan Liocichla tended to select nest sites near forest edges or gaps with good concealment and that nest-site selection by this species was nonrandom but not necessarily adaptive. Reducing forest-edge development and protecting bamboo stands should be effective for conservation of this species.

In this study,we report an unusual homing behavior of the Sichuan Partridge(Arborophila rufipectus)at the Laojunshan National Nature Reserve,Sichuan Province,*** Sichuan Partridges led the chicks back to the nests where they hatched in the evening and roosted there over *** behavior lasted 6.7±4.3 nights(range=1–15;n=13)after the chicks *** this stage,the hens became very vigilant to predators and human *** disturbed,they often abandoned the nests immediately and no longer returned *** ambient temperature at night during the early brooding period of Sichuan Partridge at our study site was^12.4°*** findings suggest that hen Sichuan Partridges may make trade-offs between nest predation risks versus the thermoregulatory needs of their young.

Temperature data loggers(TDL)are mostly used to monitor avian incubation behavior in bird *** this paper we demonstrate how TDL can also be used to determine different breeding stages and nest success of the vulnerable Emei Shan Liocichla(Liocichla omeiensis).All nests that contained at least one egg were divided into two *** I included six nests monitored traditionally by the observers’visits,while Group II included eight nests monitored by *** I and Group II were visited every 1-4 days and 7 days respectively to check the nest contents and status(e.g.,active *** and the breeding process)until fledging or nest *** time of each observation was recorded to verify the interpretation of *** data recorded by TDL were converted into line graphs of temperature against time and assessed *** results indicated that TDL could reliably identify different breeding stages and estimate daily nest survival rates(DSR)and total nest *** nest success of Group II(0.3015)was higher than that of Group I(0.2387),suggesting that deployment of TDL did not negatively influence nest survival rate of Emei Shan *** contrast to the traditional nest visits,TDL minimized observers’disturbance and provided a more precise estimate of nest *** suggest that TDL should be used more widely in studies of the breeding ecology of rare and endangered birds.

Emei Shan Liocichla: population, behavior and conservation

Chinese Birds 2013年第3期4卷 260-264页

Endemic to China, the Emei Shan Liocichla(Liocichla omeiensis) is considered globally vulnerable by the IUCN because of its small, declining population and fragmented range. The species has been recorded in only a few mountainous forests in south-central Sichuan and in the extreme northeast of Yunnan Province. We summarized the basic eco-biology information on its habitat,breeding, winter habits and behavior, voice, population status, research and conservation.

对于孵卵期的大多数鸟类而言,它们尽可能减少觅食活动以避免胚胎低温和卵捕食。单亲孵卵者面临孵卵与觅食的直接冲突。四川山鹧鸪Arborophila rufipectus是我国特产的一种珍稀濒危雉类。研究表明:雌鸟单独孵卵。孵卵期约29 d。雌鸟每天离巢一次,平均离巢时间4.7 h·day±1.1 h·day。总在巢率81.1%±5.8%。在高捕食风险和人为干扰条件下,雌鸟显著延长离巢时间和减少在巢率。卵平均每天暴露在"生理零度"(26℃)以下4.4 h。孵化率约88.4%,表明胚胎低温似乎对其孵化率影响不大。
