Recognition and rejection of foreign eggs of different colors in Barn Swallows
《Avian Research》2024年第3期374-378,共5页Kui Yan Wei Liang 
supported by the National Natural Science Foundation of China(Nos.31970427 and 32270526 to W.L.)。
Brood parasitic birds lay eggs in the nests of other birds,and the parasitized hosts can reduce the cost of raising unrelated offspring through the recognition of parasitic eggs.Hosts can adopt vision-based cognitive ...

More than a simple egg:Underlying mechanisms of cold tolerance in avian embryos被引量：2
《Avian Research》2023年第2期267-280,共14页Ibrahim M.Ahmad Dongming Li 
supported by the National Natural Science Foundation of China(NSFC,31971413)granted to DL;the Second Tibetan Plateau Scientific Expedition and Research Program(STEP,2019QZKK0501)granted to DL。
Avian embryos,which develop within eggs,exhibit remarkable tolerance to extremely low temperatures.Despite being a common trait among all birds,the mechanisms underlying this cold tolerance in avian embryos remain lar...

Light matters:Nest illumination alters egg rejection behavior in a cavity-nesting bird被引量：4
《Avian Research》2022年第1期64-67,共4页Canchao Yang Anders Pape Møller Wei Liang 
supported by the Hainan Provincial Natural Science Foundation of China (No.320CXTD437 and 2019RC189 to CY);the National Natural Science Foundation of China (Nos.31772453 and 31970427 to WL)
Egg discrimination by cavity-nesting birds that build nests under dim light conditions was presumed to depend on nest luminance,although this hypothesis has rarely been tested.Tests of egg discrimination ability by ca...

The Grey-backed Shrike parents adopt brood survival strategy in both the egg and nestling phases被引量：1
《Avian Research》2021年第1期76-85,共10页Liqing Fan Lifang Gao Zhenqin Zhu Xiaodan Zhang Wen Zhang Haiyang Zhang Jianchuan Li Bo Du 
Financial support was provided by the National Natural Sciences Foundation of China(Grant No.31672299,31572271 and 31772465);the Natural Science Foundation of Xizang Province of China(2016ZR-NY-05)。
Background:Great diversity exists in the parenting pattern of altricial birds,which has long been considered as an adaptive response to specific environmental conditions but not to their life-history style.Methods:We ...

Egg investment strategies adopted by a desertic passerine, the Saxaul Sparrow(Passer ammodendri)
《Avian Research》2020年第2期166-173,共8页Xinkang Bao Wei Zhao Fangqing Liu Jianliang Li Donghui Ma 
supported by the National Natural Science Foundation of China(Grant Nos.31672296 and 31172104)。
Background:As one of the reproductive strategies adopted by bird species,variation in investment in egg production and its influencing factors are important and well-studied subjects.Intraclutch changes in egg size as...

Last but not the least: effects of laying sequence on egg color variation and embryonic development of Russet Sparrow(Passer cinnamomeus)
《Avian Research》2018年第3期198-205,共8页Juan Huo Tongping Su Nan Niu Canchao Yang Wei Liang 
supported by the National Natural Science Foundation of China(No.31672303 to CY,and 31772453 to WL)
Background: Laying sequence has important effects on eggshell color and embryonic development in birds. Some birds can allocate resources unevenly among the eggs within a clutch, prioritizing those at the beginning of...

Incubation strategies of the Black-necked Crane(Grus nigricollis) in relation to ambient temperature and time of day
《Avian Research》2017年第3期147-155,共9页Lixun Zhang Bei An Meilin Shu Changming Zhao Xiaojun Yang Yila Suo Yongjun Se Xilite Dabu 
supported by a grant from the State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences (GREKF13-12);supported by Yanchiwan National Nature Reserve
Background: The behavior of cranes reflects many of their survival strategies, but little has been known of the incubation strategies of cranes, in which both parents share incubation duties, in response to cold tempe...
