摘要

森林伯劳鸟与其他跨撒哈拉雀鸟一起迁徙，但与其他伯劳鸟不同的是，人们并不知道它经常捕食鸟类。我们描述了在撒哈拉沙漠的一个春季中途停留点，伍德沙伯鸟捕食，狩猎和觅食候鸟。伯劳鸟捕食六种雀鸟。大多数被捕食的鸟类的身体状况比在同一地点被雾网捕获的同类更差。我们认为，Woodchat Shrikes可能更成功地捕猎候鸟，因为它们在穿越障碍时更容易被鸟类捕食者捕获。-Aispuro, a.a.， Machowetz, C.， Illa, M.， Gargallo, G. & Maggini, I.(2020)。在穿越撒哈拉的中途停留期间，伍德哈特伯劳鸟正在捕食迁徙的鸣禽。

Woodchat Shrike Lanius senator Predation on Migrating Songbirds during a Trans-Saharan Stopover

The Woodchat Shrike Lanius senator migrates alongside other trans-Saharan passerines but, unlike other shrikes, it is not known to frequently prey on birds. We describe predation, hunting and scavenging of migratory passerines by Woodchat Shrikes at a spring stopover site in the Sahara Desert. Shrikes preyed on six passerine species. Most predated birds were in poorer physical condition than their conspecifics mist-netted at the same site. We suggest Woodchat Shrikes may be more successful at hunting migratory songbirds following a debilitating barrier crossing, which may render prey more susceptible to capture by avian predators.—Aispuro, A.A., Machowetz, C., Illa, M., Gargallo, G. & Maggini, I.

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.
