"Bird-watcher" 指的是一个喜欢观察和研究鸟类的人。在英文范文中，这个词可能出现在描述一个人对鸟类的热爱和兴趣，或者在讨论生态保护和环境可持续发展等主题时。例如：
"John is a dedicated bird-watcher who spends his weekends exploring the local woods in search of new species to add to his collection of bird photos."
这段话描述了一个对鸟类观察充满热情的人，他利用周末时间去森林中寻找新的鸟类物种，并拍摄下来。
bird-watcher的意思是“观鸟者；赏鸟人”。
在英文范文里，有这样一段关于观鸟者的描述：Bird-watching is a popular activity among nature lovers, especially in areas with a rich variety of bird species. Many people enjoy spending their weekends or evenings outdoors, quietly observing the birds in their natural habitats. Bird-watchers often carry binoculars and field guides to identify different birds and learn about their habits and behaviors. This hobby not only brings people closer to nature but also helps conserve endangered species.
bird-watcher的意思是“观鸟者”。
在英文范文中最新的变化是，随着环保意识的提高，越来越多的人开始关注鸟类及其生态环境，因此“观鸟”这一活动逐渐流行起来，而“bird-watcher”这个词汇的使用频率也相应地增加。此外，随着社交媒体和在线平台的普及，观鸟爱好者们也经常在社交媒体上分享他们的观鸟经历和照片，这也进一步推动了“bird-watcher”一词的使用。
