中国鸟类新记录种——红胸姬鹟(Ficedula parva)(英文)
A New Bird Record in China : Red-breasted Flycatcher (Ficedula parva)
-
摘要: 2007年4-5月间,笔者在中国河北省乐亭县祥云岛林场及香港特别行政区蒲台岛分别记录到红胸姬鹟(Ficedula parva),为中国鸟类物种新记录。红胸姬鹟和F. albicilla原为红喉姬鹟(F. parva)的两个亚种,近年来很多著者依据形态、鸣声、分子等证据,认为两者应为在古北界异域分布(allopatric)的对种(semispecies)。本文亦就两者的鉴定特征和野外辨识要点进行了讨论。Abstract: The Red-breasted Flycatcher (Ficedula parva) and Taiga Flycatcher (F albicila) have long been considered having a conspecific status under the species Red-throated Flycatcher (F parva). Based on the studies on the morphology, vocalizations and molecular biology, the two subspecies have recently been split into separate species that are allopatrically distributed in the Palearctic region. Before our report, there was no formal record of taxon parva in China. Between April and May of 2007, two birds of parva were recorded respectively at Potoi Island, Hong Kong SAR and Xiangyundao Tree Farm, Laoting, Hebei Province, the first known recording of this species in China. We also briefly discussed the general characteristics and field identification of Red-breasted Flycatchers in this article.
