鹰利用交通灯捕猎

2025-05-27 19:15 by 电子脑叶

随着交通网络遍及世界,动物的生存空间受到了极大影响,公路上时常能看到动物被汽车撞死而留下的残骸。但与此同时,一部分动物也学会了利用无处不在的交通网,比如乌鸦被观察到将核桃丢在公路上让汽车砸碎。研究人员现在报告他们观察到鹰利用交通信号去成功捕猎小鸟。人类经常会留下食物残渣吸引鸟儿来吃。而公路上的各种声音显然会影响鸟的警惕性。研究人员观察到,鹰会借着交通声音的掩护去袭击小鸟。它们适应了城市生活。

Despite Telegram's origins, its approach to users' security has privacy advocates worried. Continuing its crackdown against entities allegedly involved in a front-running scam using messaging app Telegram, Sebi on Thursday carried out search and seizure operations at the premises of eight entities in multiple locations across the country. Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegram’s FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links. 'Wild West' Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress.
