Abstract

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.

在穿越撒哈拉的中途停留期间，森林伯劳鸟捕食迁徙的鸣禽

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
