成都平原城区毛叶钝果寄生果实取食鸟类调查

Ingestion Species and Ingestion Intensity of Birds on Taxillus nigrans in the Urban of Chengdu Plains

  • 摘要: 为研究秋冬季取食桑寄生科(Loranthaceae)植物毛叶钝果寄生(Taxillus nigrans)果实的鸟类种类及其取食强度,于2013年10月10日至2013年12月19日在成都市四川大学望江校区调查了造访毛叶钝果寄生丛的鸟类种类和频次,以及取食其果实的鸟类种类和频次。期间共有19种鸟造访了毛叶钝果寄生丛,其中有11种鸟取食毛叶钝果寄生果实。观察到白头鹎(Pycnonotus sinensis)每天都取食毛叶钝果寄生的果实,取食日百分比为100%,红胸啄花鸟(Dicaeum ignipectus)在10月不取食该物种,在11月~12月取食。不同鸟类的取食强度存在差异,取食强度最大的鸟类为红胸啄花鸟,其他依次为白头鹎、黑头蜡嘴雀(Eophona personata)、黑尾蜡嘴雀(Eophona migratoria)、淡黄腰柳莺(Phylloscopus chloronotus)、黄腹山雀(Pardaliparus venustulus)、红胁绣眼鸟(Zosterops erythropleurus)、红头长尾山雀(Aegithalos concinnus)、白颊噪鹛(Garrulax sannio)和金翅雀(Chloris sinica)。

     

    Abstract: In order to reveal visiting and ingestion bird species and their ingestion intensity on Taxillus nigrans,one of the parasitic Loranthaceae species in autumn and winter,investigetions were made on the bird species,visiting times,and ingestion times from October 10,2013 to December 19,2013.There were 19 species visiting T.nigrans,among which,11 species ingested fruits.Pycnonotus sinensis was the only species which ingested fruits on every censored day,and the ratio of ingestion days was 100%.Dicaeum ignipectus ingested fruits in November and December.The ingestion intensity with bird species was various,D.ignipectus had a most intensive ingestion degree,and then in descending order came Pycnonotus sinensis, Eophona personata, E.migratoria, Phylloscopus chloronotus, Pardaliparus venustulus,Zosterops erythropleurus,Aegithalos concinnus,Garrulax sannio,and Chloris sinica.
