Sierra de Bahoruco Constant-effort Mist Netting
收藏资源简介:
Data were collected during 22 visits to two sites in Sierra de Bahoruco National Park, Dominican Republic, from 1995 - 2010. During each visit, we operated a standardized array of 30-35 mist nets (12-m x 2.6-m, 36-mm mesh) at each site. Detailed information on capture effort is included in this data set. We placed U.S. Fish and Wildlife Service aluminum leg bands on all North American migrant species and custom-made, uniquely numbered leg bands (Gey Band and Tag Company) on all Hispaniolan resident species. We did not have leg bands that fit Hispaniolan Emeralds (Chlorostilbon swainsonii), so we temporarily marked individuals of this species by clipping the distal 2-3 mm of up to three rectrices in a unique pattern; doing so allowed us to identify within-session recaptures. We aged and sexed all North American species using standard criteria according to Pyle (1997) and all resident species using criteria available in field guides (Latta et al., 2006) or based on our own accumulated field knowledge.
本数据集的野外数据采集工作于1995年至2010年间完成,累计开展22次野外调查,调查地点为多米尼加共和国巴霍鲁科山脉国家公园(Sierra de Bahoruco National Park)内的两处监测位点。每次调查中,我们在每个监测位点布设标准化雾网(mist nets)阵列,单套网具规格为12米×2.6米,网孔孔径36毫米,单站点布设30至35套。本数据集收录了关于捕获努力量(capture effort)的详细信息。我们为所有北美迁徙鸟类佩戴美国鱼类及野生动物管理局(U.S. Fish and Wildlife Service)制式铝制脚环;对于所有伊斯帕尼奥拉岛留居鸟类,则佩戴由Gey Band and Tag Company定制的专属编号脚环。因缺乏适配伊斯帕尼奥拉蜂鸟(Chlorostilbon swainsonii)的脚环,我们采用临时标记手段:以独特方式剪去该物种最多3枚尾羽的末端2至3毫米,以此实现同调查周期内的个体重识别。我们依据Pyle(1997)提出的标准鉴定方法,对所有北美迁徙鸟类进行年龄与性别判定;对于留居鸟类,则采用Latta等人(2006)出版的野外手册中的鉴定标准,或结合自身积累的长期野外调研经验完成鉴定。
