广西发现黑头鹀

2018年10月30日清晨,在广西壮族自治区北海市银海区冠岭路旁的一片稻田(109°04’07’’N,21°27’27’’E)间的灌丛中观察到1只小型雀形目鸟类,体长较麻雀(Passer montanus)略大,约16～17 cm;嘴大而厚,呈褐色;上体灰褐色,具暗色纵纹;头顶具有明显的深色纵纹,颊和耳羽灰褐色;喉部略沾棕黄色;飞羽和尾羽褐色,翅上覆羽暗褐色并有污白色羽缘;胸腰和尾上覆羽棕黄色;下体污黄色,胸具深色纵纹;尾下覆羽明黄。经查阅相关文献和野外识别图鉴(约翰×马敬能等2000,赵正阶2001,Svensson et al. 2010,Copete 2018),确认该鸟为黑头鹀(Emberiza melanocephala)亚成体第一年冬羽或雌鸟(图1)。其与褐头鹀(E. bruniceps)雌鸟或第一年冬羽亚成体非常相似,但前额与头顶具明显的深色纵纹,腰棕黄色(赵正阶2001,Svensson et al. 2010,Copete 2018)

Effect of colonial breeding of Chinese Egret(Egretta eulophotes) on the heavy metal accumulation in heronry soil

本研究采用电感耦合等离子质谱(ICP-MS)方法,测定福建漳浦菜屿岛黄嘴白鹭(EgrETTAEulOPHOTES)排泄物的重金属元素(V、Cr、Mn、nI、Cu、zn、Cd、SE、Pb)及半金属元素(AS)的含量,分析比较黄嘴白鹭繁殖之前和繁殖之后的集群营巢地、非营巢地的表层土壤的重金属元素及半金属元素含量的变化。结果显示:在本次测定的所有排泄物和土壤样本中均未检出元素SE和Cd;非营巢地土壤中各元素的含量在繁殖前后都没有显著差异(P>0.05),营巢地土壤中的zn和Pb元素的含量在繁殖前后有极显著差异(P 0.05),but the differences in concentrations of Zn and Pb in the nesting soil were highly significant before and after breeding(p < 0.01).A comparison of the concentrations of the elements in the nesting and non-nesting soils also reveals that before breeding,the concentration of Zn in these two soils were significantly different(p < 0.01).After breeding,concentrations of Cu,Zn,As and Pb in the nesting and non-nesting soil were significantly different(p < 0.01) while V and Ni concentrations showed merely significant differences(p < 0.05).These findings indicate that the colonial breeding activities of E.eulophotes play an important role in the transfer of heavy metals between wetland and island eco-systems and that such activities may,over time,result in heavy metal contamination of the heronry soil on the island.supportedbytheNationalNaturalScienceFoundationofChina(GrantNos.40876077;30970380);theFujianNaturalScienceFoundationofChina(2008S0007;2009J01195

Bird in Southern Fujian mangrove areas and Its correlationship with macrobenthic

红树林是分布于热带河口海湾潮间带的木本植物群落。由于红树林生长的潮滩含有大量的有机碎屑，为滩涂上的底栖动物提供了大量的能量来源，底栖动物比较丰富，可以为鸟类提供大量的食物来源，同时红树林又为鸟类提供了栖息，繁殖的场所，因而在红树林区鸟类的物种多样性较高。 本研究从1999年12月至2003年3月对漳州云霄漳江口、泉州洛江口、厦门东屿和厦门凤林4地红树林区鸟类进行为期3年4个月的调查。分析闽南沿海地区红树林区鸟类的种类、区系组成和时间动态；讨论红树林对鸟类种类和数量分布的影响；以及生境变迁对鸟类影响。研究云霄漳江口和泉州洛江口红树林区滩涂大型底栖动物密度、生物量和去灰分生物量的时间动态及其与鸟...Bird in Southern Fujian mangrove areas and its correlationship with macrobenthic Lin Qingxian Abstract: Mangroves are woody plant communities in the intertidal zone of tropical coast.

The Effect of Environment Changing on Birds at Dongyu Mangrove Area,Xiamen

比较厦门东屿红树林区两次鸟类调查数据(2002年1月~2003年1月与1996年1月~1997年1月),分析当地生境的变化对鸟类物种组成及主要鸟类类群数量的影响.与1996年相比,2002年的鹭类、鸥类和鸭类年累计数量分别从2 4443、023和873只减少到352、73和10只,而鸻鹬类从3 088只增加到5 478只.滩涂、红树林面积减少及人为活动增加是鹭类、鸥类和鸭类数量减少的主要原因,而鸻鹬类数量增加与新增荒废裸地生境为其提供理想休息场所关系密切.By comparing the data of birds between in 2002-01~2003-01 and in 1996-01~1997-01 at Dongyu mangrove areas,Xiamen,the effect of environment changing on bird′s species,quantity was analyzed.The exploitation resulted in diversification of habitat type which increasing some bird species,on the other hand,mangrove and mudflat reducing resulted in disappear of some species.64 bird species were recorded in 1996-01~1997-01 and 72 species were recorded in 2002-01~2003-01.There were 44 different species in the two indagations,among which 26 new species appearing and 18 species disappearing in 2002-01~2003-01.The habitat changing also resulted in the dominant species changing.Ardeola bacchus,Casmerodius albus,Tringa tetanus,Tringa nebularia,Larus ridibundus and Anas crecca were dominant species in 1996-01~1997-01,but they were not dominant species in 2002-01~2003-01,Charadrius leschenaultia and Passer montanus were new increased dominate species in 2002-01~2003-01.The quantity of some main water-bird flocks were changed sharply from 1996 to 2002.By comparing with 1996,the quantity of herons,ducks and gulls in 2002 was from 2 444,3 023 and 873 reduced to 352,73 and 10,but the quantity of chardrii was increased form 3 088 to 5 478.Some reasons that lead to the changing of birds were discussed in paper.国家自然科学基金(40276028);; 厦门大学科技创新项目(XDKJCX20041021)资
