摘要

总结。濒临灭绝的草原鹰是巴基斯坦的冬季候鸟，但关于其目前分布和种群状况的基线数据很少。本研究调查了Azad查谟和克什米尔的Poonch和Jhelum山谷的新分布记录，超出了世界自然保护联盟目前巴基斯坦分布地图的范围。它使已知的越冬范围又增加了6730平方公里。在两年的调查中，平均每年有154只成年和未成熟的混合越冬群体。这里平均有10只鸟，从Hajira垃圾场的63只到Kalas垃圾场的2只不等。来自屠宰场和其他人为来源的废物似乎是主要的食物来源，因为最大的鹰集中在垃圾场。建议在越冬范围图中增加研究区，并建议每年进行种群监测。——bari, F.， Rehman, eu, Kabir, M. & Ahmad, S.(2020)。在巴基斯坦查谟和克什米尔的Poonch和Jhelum山谷，已知的草原鹰Aquila nipalensis越冬范围的延伸。Ardeola, 67: XX-XX。

An Extension to the Known Wintering Range of the Steppe Eagle Aquila nipalensis, in the Poonch and Jhelum Valleys, Azad Jammu and Kashmir, Pakistan

Summary. The endangered Steppe Eagle Aquila nipalensis is a winter migrant to Pakistan but baseline data regarding its current distribution and population status there is sparse. The present study investigated new distributional records from the Poonch and Jhelum valleys of Azad Jammu and Kashmir, beyond the range of the current IUCN distribution map for Pakistan. It adds another 6,730km2 to the known wintering range. Mixed wintering groups of adults and immatures, averaging 154 individuals annually, were counted in two survey years. Site counts averaged ten birds and ranged from 63 at Hajira, a waste dump, to just two, at Kalas. waste from slaughterhouses and other anthropogenic sources appeared to be the main food source since the largest eagle concentrations were at dump sites. we suggest that the addition of the study area to the wintering range map of the species and recommend annual monitoring of the population. —Bari, F., Rehman, E.U., Kabir, M. & Ahmad, S.

期刊介绍： Ardeola: International Journal of Ornithology is the scientific journal of SEO/BirdLife, the Spanish Ornithological Society. The journal had a regional focus when it was first published, in 1954. Since then, and particular during the past two decades, the journal has expanded its thematic and geographical scope. It is now a fully international forum for research on all aspects of ornithology. We thus welcome studies within the fields of basic biology, ecology, behaviour, conservation and biogeography, especially those arising from hypothesis-based research. Although we have a long publication history of Mediterranean and Neotropical studies, we accept papers on investigations worldwide. Each volume of Ardeola has two parts, published annually in January and July. The main body of each issue comprises full-length original articles (Papersand Review articles) and shorter notes on methodology or stimulating findings (Short Communications). The publication language is English, with summaries, figure legends and table captions also in Spanish. Ardeolaalso publishes critical Book Reviewsand PhD-Dissertation Summaries; summarising ornithological theses defended in Spain. Finally there are two Spanish-language sections, Ornithological News; summarising significant recent observations of birds in Spain, and Observations of Rare Birds in Spain, the annual reports of the Spanish Rarities Committee.
