摘要
贵州省紫云县是近年新发现黑颈长尾雉(Syrmaticus humiae)北扩的集中分布区。2021年1月—2022年2月,利用红外相机技术手段,采用核密度估计法及重叠指数分析黑颈长尾雉的日活动节律和季节性差异,同时对黑颈长尾雉集群行为进行调查。结果表明:46台相机累计工作12664 d,共获得独立有效照片508张,合计570只次;黑颈长尾雉主营昼行性活动,雌性与雄性个体均在07:00—09:00、17:00—19:00有两个地面活动高峰期,日活动强度在繁殖期与非繁殖期差异均不显著(P>0.05);主要行为是觅食和位移,其中雄性觅食与位移行为分别占总频次的47.32%和34.23%,雌性占56.76%和27.76%;在各月份间的相对活动强度存在显著性差异(P<0.05),活动频率在10月达到峰值;黑颈长尾雉数量为2只的群体占比最大,占总体的73.81%,以混合集群为主,集群方式在繁殖与非繁殖季存在显著差异(P<0.01)。本研究为该区域黑颈长尾雉的保护管理及该物种的生态学研究提供科学参考。
We examined the activity patterns and time budget for a recently discovered population of the Hume’s Pheasant(Syrmaticus humiae)in Ziyun County,Guizhou Province.This new distribution location is a result of its range expansion.We conducted a monitoring program by infrared cameras for the pheasant from January 2021 to February 2022.A total of 46 infrared cameras were set and 508 independent effective photos with 570 individuals of S.humiae were observed during 12664 working days.The differences in daily activity rhythm and seasonal difference of S.humiae were analyzed by kernel density estimation and coefficient of overlap.Based on the analysis on the infrared camera data,the ground behavior of the pheasant showed that S.humiae was a diurnal bird.All activities of the Hume’s Pheasant occurred between 06:00-20:00 with two diurnal peak periods of ground activity at 07:00-09:00 and 17:00-19:00 for both female and male individuals.There was no significant difference in daily activity intensity between breeding season and non-breeding season(P>0.05).Activities of the pheasant mainly included foraging and wandering,with time allocations of the two activities being 47.32%and 34.23%in males and 56.76%and 27.76%in females,respectively.There was a significant difference in the relative activity intensity across months(P<0.05),which generally peaked in October.Flocks comprised of two individual pheasants,especially a male and a female,were the major flock type occupying 73.81%of the total.Flock types were significantly different between breeding season and non-breeding season(P<0.01).The results provide a scientific reference for the conservation and management of the Hume’s Pheasant in this area and for the subsequent ecological research on this species.
