This phenomenon does more than just signal seasonal change — it offers scientifically proven benefits for our mental well-being. Social psychologist Cindy Franz explains this connection stems from our human wiring — just as we are biologically wired to form social bonds with other people, we possess an inborn capacity to build meaningful connections with nature, including our feathered companions. A growing body of research demonstrates how birdsong serves as a powerful gateway to nature's restorative (促进康复的) effects. In a comprehensive 2022 study published in Scientific Reports, researchers tracked over 1,300 participants who documented their environment and emotional state multiple times daily for two weeks. The results revealed that encounters with birds, whether visual or auditory (听觉), provided significant boosts to mental well-being that surpassed the benefits of simply being near green spaces or water features. Remarkably, these positive psychological effects persisted for several hours after each bird encounter. Further evidence comes from another 2022 study in the same journal, where researchers exposed 295 participants to different sound environments. Those who listened to six minutes of birdsong through headphones reported measurable reductions in feelings of depression, anxiety and paranoia (妄想症). In contrast, the group subjected to traffic noise experienced the opposite effect. The study yielded another fascinating discovery: the mental health benefits increased substantially when participants heard multiple bird species singing together compared to just two species. This suggests that biodiversity in birdsong may enhance its therapeutic (治疗的) value. While researchers acknowledge potential limitations, the consistent findings highlight birdsong's unique psychological value. Scientists will continue investigating why varied birdsong delivers greater benefits, but evidence clearly shows it offers universal access to nature's restorative power, whether in cities or countryside. As research progresses, we may gain deeper understanding of how these ancient natural sounds continue to soothe (抚慰) modern minds. 语篇解读：本文是一篇说明文。文章介绍了科学研究证实鸟类鸣叫能显著促进心理健康，且多样性鸣叫疗效更佳，这可能源于人类与自然联结的先天倾向。 √ 1．What did the 2022 study with 1,300 participants find about bird encounters?
