Protected areas are seeing an increase in anthropogenic disturbances in the world. Previous studies have demonstrated the impact of livestock grazing and human presence on the habitat use of birds, whereas little is known about the effect of free-ranging livestock on bird behaviour. Reeves's Pheasant () is endemic to China and has been threatened by habitat loss and fragmentation, illegal logging, and human disturbance over the past 20 years. Based on camera trapping in the Liankangshan National Nature Reserve (LKS) and the Zhonghuashan Birds Provincial Nature Reserve (ZHS), we explore the effects of livestock grazing and human activities on the spatio-temporal distribution and behavioural patterns of Reeves's Pheasant. Livestock does not appear to affect habitat use by the pheasant but changes its behavioural patterns. In addition, pheasants in areas with livestock foraged mostly during the early morning, while in areas without livestock, they foraged at dusk. Therefore, the study concludes that livestock intensity in nature reserves may have reduced pheasant suitability through altered patterns of vigilance and foraging behaviour.
在全球范围内,保护区受到的人为干扰正在增加。先前的研究已经证明了牲畜放牧和人类活动对鸟类栖息地利用的影响,而关于散养牲畜对鸟类行为的影响却知之甚少。白冠长尾雉()是中国特有的物种,在过去20年里,它一直受到栖息地丧失和破碎化、非法伐木以及人类干扰的威胁。基于在联康山国家级自然保护区(LKS)和中华山鸟类省级自然保护区(ZHS)的相机监测,我们探究了牲畜放牧和人类活动对白冠长尾雉时空分布和行为模式的影响。牲畜似乎并未影响雉鸡对栖息地的利用,但改变了其行为模式。此外,有牲畜区域的雉鸡大多在清晨觅食,而在没有牲畜的区域,它们在黄昏时觅食。因此,该研究得出结论,自然保护区内的牲畜密度可能通过改变警戒和觅食行为模式而降低了雉鸡的适宜度。
